JavaScript:

javascript
 
 
Copy code
function celsiusToFahrenheit(celsius) {
  let fahrenheit = (celsius * 9/5) + 32;
  return fahrenheit;
}

let celsiusValue = 25;
let fahrenheitValue = celsiusToFahrenheit(celsiusValue);
console.log(fahrenheitValue);

In the above code, we have a function celsiusToFahrenheit that accepts a temperature in Celsius as a parameter and calculates the equivalent temperature in Fahrenheit. The formula used is (celsius * 9/5) + 32.

Then, we have a variable celsiusValue that holds the Celsius temperature we want to convert (in this case, 25). We pass this value to the celsiusToFahrenheit function and store the returned Fahrenheit temperature in a variable fahrenheitValue.

Finally, we log the value of fahrenheitValue to the console, which will print the equivalent Fahrenheit value.

To convert Celsius to Fahrenheit, you can use the following formula:

javascript
 
 
Copy code
function celsiusToFahrenheit(celsius) {
  let fahrenheit = (celsius * 9/5) + 32;
  return fahrenheit;
}

let temperatureInCelsius = 25;
let temperatureInFahrenheit = celsiusToFahrenheit(temperatureInCelsius);

console.log(temperatureInFahrenheit);

Here's an example:

If you have a temperature of 25 degrees Celsius, the code above will convert it to Fahrenheit, which is 77 degrees.

javascript
 
 
Copy code
console.log("Temperature on Monday is 18 degrees");
console.log("Temperature on Tuesday is 20 degrees");
console.log("Temperature on Wednesday is 22 degrees");
console.log("Temperature on Thursday is 19 degrees");
console.log("Temperature on Friday is 17 degrees");
console.log("Temperature on Saturday is 16 degrees");
console.log("Temperature on Sunday is 21 degrees");

Note: This is just an example. Please replace the values with the actual temperature if available.

html
 
 
Copy code
<!-- Create a HTML container to display the logs -->
<div id="temperature-logs"></div>

javascript
 
 
Copy code
// Store the temperature values in an object
const temperature = {
  monday: 18,
  tuesday: 20,
  wednesday: 22,
  thursday: 19,
  friday: 17,
  saturday: 16,
  sunday: 19
};

// Get the reference to the HTML container
const temperatureLogs = document.getElementById('temperature-logs');

// Loop through the object to log the temperature values for each day
for (const day in temperature) {
  const message = `Temperature on ${day} is ${temperature[day]} degrees`;
  temperatureLogs.innerHTML += `<p>${message}</p>`;
}

css
 
 
Copy code
/* Style the HTML container */
#temperature-logs {
  background-color: #f9f9f9;
  padding: 20px;
  border: 1px solid #ddd;
  border-radius: 5px;
  font-size: 16px;
  margin: 20px;
}

/* Style the log message */
#temperature-logs p {
  margin: 5px 0;
}

To convert Celsius to Fahrenheit, you can use the following formula: (Celsius * 9/5) + 32 = Fahrenheit.

Here is an example in JavaScript:

javascript
 
 
Copy code
function celsiusToFahrenheit(celsius) {
  const fahrenheit = celsius * 9/5 + 32;
  return fahrenheit;
}

console.log(celsiusToFahrenheit(25)); // Output: 77

In this example, we defined a function that takes in a Celsius value as a parameter and returns the Fahrenheit equivalent. We then logged the result of calling this function with the argument of 25 to the console.

Here is an example code to create a 1 row table with 6 columns in Bootstrap, with a small image, date text above the image and temperature text below the image:

html
 
 
Copy code
<div class="container">
  <div class="row">
    <div class="col-sm-2">
      <img src="your-image-path" alt="your-image-description" class="img-fluid">
    </div>
    <div class="col-sm-4">
      <h6>Date text</h6>
    </div>
    <div class="col-sm-4">
      <p>Temperature text</p>
    </div>
  </div>
</div>

You can replace "your-image-path" with a valid image file path and "your-image-description" with a brief description of the image. You can modify the width of the columns by changing the "col-sm-2", "col-sm-4" values. The "img-fluid" class makes the image responsive.

To convert a temperature from Celsius to Fahrenheit, you can use the following formula in JavaScript:

javascript
 
 
Copy code
let celsius = 28;
let fahrenheit = (celsius * 9/5) + 32;
console.log(fahrenheit);
// Output: 82.4

Where celsius is the temperature in Celsius and fahrenheit is the equivalent temperature in Fahrenheit. The formula multiplies the temperature in Celsius by 9/5 (or 1.8) and then adds 32 to get the temperature in Fahrenheit.

To use this formula, simply replace the value of celsius with the temperature you want to convert. In this example, the original temperature is 28 Celsius which converts to 82.4 Fahrenheit.

To ask for the temperature of a city using OpenWeather, you can follow these steps:

Step 1: Get the API key

Visit the OpenWeatherMap website and create an account. After logging in, you can find your API key in the "API keys" section of the "My account" page.

Step 2: Find the city ID

Next, you need to obtain the ID of the city for which you want the temperature. Use the following URL to search for the city ID:

code
 
 
Copy code
http://api.openweathermap.org/data/2.5/find?q={CITY NAME}&appid={API KEY}

Replace {CITY NAME} with the name of the city you want to search for and {API KEY} with the API key you obtained in step 1. You will receive a JSON response which contains a list of cities that match the search criteria. Find the desired city in the response and note its id field.

Step 3: Get the current temperature

Now that you have the city ID, you can use the following URL to obtain the current weather information for the city:

code
 
 
Copy code
http://api.openweathermap.org/data/2.5/weather?id={CITY ID}&units=metric&appid={API KEY}

Replace {CITY ID} with the ID of the desired city and {API KEY} with the API key you obtained in step 1. You will receive a JSON response which contains various weather parameters for the city, including the main.temp field which represents the current temperature in Celsius.

Step 4: Display the temperature

To display the temperature on a webpage, you can use HTML to create a placeholder element and JavaScript to fetch the weather information and update the element with the temperature.

HTML code:

html
 
 
Copy code
<p>The current temperature in <span id="city"></span> is <span id="temp"></span>°C</p>

JavaScript code:

javascript
 
 
Copy code
const apiKey = "your-api-key";
const cityId = "your-city-id";

fetch(`http://api.openweathermap.org/data/2.5/weather?id=${cityId}&units=metric&appid=${apiKey}`)
  .then(response => response.json())
  .then(data => {
    const city = data.name;
    const temp = data.main.temp;
    document.getElementById("city").textContent = city;
    document.getElementById("temp").textContent = temp;
  })
  .catch(error => console.error(error));

Replace your-api-key with the API key you obtained in step 1 and your-city-id with the ID of the desired city you obtained in step 2. You can place this JavaScript code in a <script> tag in the <head> section of your HTML file.

To display the temperature for a city after a user clicks the button Enter a city, you need to create an HTML form with an input field where the user can enter the city name. You can then use a server-side scripting language such as JavaScript and an API from a weather service provider, such as OpenWeather, to fetch the temperature data for that city. Once the data is returned, you can use JavaScript to display the temperature on the webpage.

Here's an example in JavaScript using the OpenWeather API:

javascript
 
 
Copy code
const form = document.querySelector('form');
const input = document.querySelector('input');
const tempDisplay = document.querySelector('#temperature');

form.addEventListener('submit', event => {
  event.preventDefault();

  const apiKey = {Insert Your API Key Here};
  const cityName = input.value.trim();

  fetch(`https://api.openweathermap.org/data/2.5/weather?q=${cityName}&units=metric&appid=${apiKey}`)
    .then(response => response.json())
    .then(data => {
      const temperature = data.main.temp;
      tempDisplay.textContent = `The temperature in ${cityName} is ${temperature}°C`;
    })
    .catch(error => {
      console.error(error);
      tempDisplay.textContent = `Couldn't retrieve temperature for ${cityName}. Please try again later.`;
    });
});

In this example, we listen for the form's submit event and prevent its default behavior (refreshing the page). We then get the input value, append it to the OpenWeather API URL along with the API key and the unit of measurement we want to use (metric in this case), and fetch the data using the fetch() method. We then extract the temperature from the JSON response and display it in the tempDisplay element. If there's an error, we log it to the console and display an error message in the same element.

Note that you will need to sign up for a free API key from OpenWeather to use their service.

To display the temperature and name of a city on a webpage, you can use an API (Application Programming Interface) like OpenWeatherMap. You can make a request to the API using JavaScript and then display the city name and temperature on your webpage.

Here's an example using JavaScript:

javascript
 
 
Copy code
// replace CITY_NAME and API_KEY with your own values
const apiURL = `https://api.openweathermap.org/data/2.5/weather?q=CITY_NAME&appid=API_KEY&units=metric`;

async function getWeather() {
  const response = await fetch(apiURL);
  const weatherData = await response.json();
  const cityName = weatherData.name;
  const temperature = weatherData.main.temp;
  document.getElementById("city-name").innerText = cityName;
  document.getElementById("temperature").innerText = temperature + "°C";
}

getWeather();

In this example, we're using the fetch function to make a request to the OpenWeatherMap API. We pass in the city name and API key as parameters in the URL.

Once we get the weather data, we extract the city name and temperature from the response JSON object. We then set the innerText of two HTML elements with the id "city-name" and "temperature" to display the city name and temperature on the page.

Note that you'll need to sign up for an API key with OpenWeatherMap to use their API. You can follow their documentation to get started: https://openweathermap.org/api.

javascript
 
 
Copy code
// Create an array of 3 cities
const cities = ['New York', 'Tokyo', 'London'];

// Create an object with temperatures for each city
const temperatures = {
  'New York': 20,
  'Tokyo': 25,
  'London': 18
};

// Loop through the cities and console log each city temperature
cities.forEach(city => {
  console.log(`${city}: ${temperatures[city]} degrees Celsius`);
});

This code creates an array of 3 cities and an object with their respective temperatures. It then loops through the cities array and logs each city's temperature to the console.

javascript
 
 
Copy code
// Define the properties of a city
const paris = {
  name: "Paris",
  population: 2.2,
  country: "France",
  temperature: 19
};

// Create an array of 3 cities with the same properties as Paris
const cities = [
  {
    name: "New York",
    population: 8.3,
    country: "USA",
    temperature: 24
  },
  {
    name: "Tokyo",
    population: 37.4,
    country: "Japan",
    temperature: 26
  },
  {
    name: "Sydney",
    population: 5.3,
    country: "Australia",
    temperature: 21
  }
];

// Console log each city temperature
cities.forEach(city => console.log(city.temperature));

Note: This code creates an array of three different cities with the same properties as Paris, console logs each of their temperatures, and logs them to the console. If you need to add more cities, simply copy the same properties and add a new object to the cities array.

javascript
 
 
Copy code
// Object with City Temperature
const paris = {
  temperature: 20 // Temperature in Celsius
}

// Log temperature of Paris
console.log(paris.temperature);

The output on the console will be 20.

There are several Geolocation APIs available, including Google Maps API and OpenStreetMap API. These APIs allow you to retrieve information about a location such as its latitude, longitude, and address. Once you have the location information, you can use a weather API to retrieve the temperature at that location.

Here is an example of how you might use the OpenWeatherMap API to retrieve the temperature at a given latitude and longitude using JavaScript:

javascript
 
 
Copy code
const lat = 51.5074; // example latitude
const lon = 0.1278; // example longitude
const apiKey = 'your-api-key'; // replace with your API key from OpenWeatherMap

const apiUrl = `https://api.openweathermap.org/data/2.5/weather?lat=${lat}&lon=${lon}&appid=${apiKey}`;

fetch(apiUrl)
  .then(response => response.json())
  .then(data => {
    const temp = data.main.temp;
    console.log(`The temperature is ${temp} Kelvin.`);
  })
  .catch(error => console.log(error));

In this example, the latitude and longitude are hardcoded, but you could retrieve them dynamically using a Geolocation API. The OpenWeatherMap API is used to retrieve the weather information at the given location, and then the temperature is logged to the console. Remember to replace 'your-api-key' with your personal API key.

You can log the current temperature of a city by using an API that provides weather information. One common weather API is OpenWeatherMap.

To get the current temperature of a city using OpenWeatherMap API, you can make an HTTP request to the API with the city name and your API key, and then extract the temperature from the response.

Here's an example code in JavaScript:

javascript
 
 
Copy code
const api_key = 'YOUR_API_KEY';
const city_name = 'London';

fetch(`https://api.openweathermap.org/data/2.5/weather?q=${city_name}&appid=${api_key}`)
  .then(response => response.json())
  .then(data => {
    const temp = data.main.temp;
    console.log(`The current temperature in ${city_name} is ${temp} K`);
  })
  .catch(error => console.error(error));

In this example, we're using the fetch() function to make an HTTP GET request to the OpenWeatherMap API with the city name (in this case, London) and our API key. We're then extracting the temperature information from the response using data.main.temp and logging it to the console. Note that the temperature is returned in Kelvin.

To accomplish this, you would need to create a function that retrieves the desired city and temperature values and then displays them when the button is clicked. Assuming you are working with web development, here's an example using JavaScript:

javascript
 
 
Copy code
// HTML code
<button onclick="displayCityAndTemp()">Display City and Temperature</button>
<p id="city"></p>
<p id="temp"></p>

// JavaScript function
function displayCityAndTemp() {
  // Retrieve city and temperature values
  const city = "New York";
  const temp = "72°F";
  // Display city and temperature values
  document.getElementById("city").innerHTML = `City: ${city}`;
  document.getElementById("temp").innerHTML = `Temperature: ${temp}`;
}

In this example, the displayCityAndTemp() function is triggered when the button is clicked. It retrieves the city and temperature values (in this case hardcoded for demo purposes), and then uses document.getElementById() to update the HTML of the

elements with the IDs "city" and "temp" to display the values.

Note: Depending on your specific use case, you may need to modify this code to retrieve the desired city and temperature values (e.g. from a database or API), but the basic idea of using a function triggered by a button click remains the same.

javascript
 
 
Copy code
// create an array of 3 cities with temperature property
const cities = [
  { name: 'New York', temperature: 20 },
  { name: 'Paris', temperature: 18 },
  { name: 'Tokyo', temperature: 26 }
];

// console log each city temperature
cities.forEach(city => {
  console.log(`${city.name} temperature is ${city.temperature}°C`);
});

This code creates an array of 3 cities with a temperature property, one for each city. Then, it loops over the cities array using the forEach method to log each city's temperature using string interpolation.

javascript
 
 
Copy code
// This code is not necessary for the task assigned in the instructions.
// It is only included as an example of how you could use JavaScript to modify the temperature displayed.

const temperatures = document.querySelectorAll('.temperature');

temperatures.forEach(function(temp) {
  let celcius = parseInt(temp.textContent);
  let fahrenheit = Math.round((celcius * 9/5) + 32);
  let newTemp = `${celcius}°C / ${fahrenheit}°F`;
  temp.textContent = newTemp;
});

To display the degree symbol at the top right of the temperature, you can use the Unicode character \u00B0. In HTML, you can use the HTML entity ° or the sup tag with the degree symbol. Here's an example in JavaScript:

javascript
 
 
Copy code
let temperature = 25;
let result = temperature + '\u00B0';

console.log(result); // Output: "25°"

In HTML, you can use the sup tag with the degree symbol like this:

html
 
 
Copy code
<p>Temperature: 25<sup>&deg;</sup></p>

This will display the temperature value with the degree symbol at the top right of the number.

Assuming you want to display the temperature of 21 degrees in Celsius with the degree symbol, you can simply concatenate "°C" at the end of the temperature value.

Here's an example in JavaScript:

code
 
 
Copy code
let temperature = 21;
temperature += "°C"; // add the degree symbol and "C" to the temperature value
console.log(temperature); // output: "21°C"

Alternatively, you can use a template literal to achieve the same result:

code
 
 
Copy code
let temperature = 21;
console.log(`${temperature}°C`); // output: "21°C"

To display a list of days of the week and their temperatures using a loop in JavaScript, you can create an array of objects where each object represents a day of the week and its temperature. Then, you can loop through the array and display each day's information.

Here's an example code snippet:

javascript
 
 
Copy code
// create an array of objects representing each day of the week and its temperature
const daysOfWeek = [
  { day: "Monday", temperature: 20 },
  { day: "Tuesday", temperature: 22 },
  { day: "Wednesday", temperature: 18 },
  { day: "Thursday", temperature: 25 },
  { day: "Friday", temperature: 19 },
  { day: "Saturday", temperature: 23 },
  { day: "Sunday", temperature: 21 }
];

// loop through the array and display each day's information
for (let i = 0; i < daysOfWeek.length; i++) {
  console.log(`${daysOfWeek[i].day}: ${daysOfWeek[i].temperature} degrees`);
}

This code will output the following:

code
 
 
Copy code
Monday: 20 degrees
Tuesday: 22 degrees
Wednesday: 18 degrees
Thursday: 25 degrees
Friday: 19 degrees
Saturday: 23 degrees
Sunday: 21 degrees

Note that this is a simplified example and you can modify the code to suit your specific needs. You can find more information on JavaScript arrays and loops in the following links:

• JavaScript Arrays
• JavaScript Loops

code
 
 
Copy code
// JavaScript weather search engine using fake data

// fake data for demo purposes
const cities = [
  { name: "New York", temperature: "13", weather: "Cloudy" },
  { name: "San Francisco", temperature: "20", weather: "Sunny" },
  { name: "London", temperature: "8", weather: "Rainy" },
  { name: "Sydney", temperature: "25", weather: "Sunny" },
  { name: "Tokyo", temperature: "15", weather: "Partly Cloudy" }
];

// function to search for a city's weather
function searchCity(cityName) {
  // iterate through the fake data to find a match
  for (let i = 0; i < cities.length; i++) {
    if (cities[i].name.toLowerCase() === cityName.toLowerCase()) {
      // if a match is found, return the temperature and weather
      const cityTemp = cities[i].temperature;
      const cityWeather = cities[i].weather;
      return `The temperature in ${cityName} is ${cityTemp}C and it is ${cityWeather} today.`;
    }
  }
  // if no match is found, return an error message
  return `Sorry, we could not find any weather data for ${cityName}.`;
}

// example usage
console.log(searchCity("San Francisco")); // output: The temperature in San Francisco is 20C and it is Sunny today.
console.log(searchCity("Paris")); // output: Sorry, we could not find any weather data for Paris.

This is a simple weather search engine using fake data. The code is written in JavaScript. It consists of a cities array containing fake data for demonstration purposes, and a function called searchCity that takes a cityName parameter and searches for a corresponding city in the cities array.

If a match is found, the function returns a string with the temperature and weather for that city. If no match is found, the function returns an error message.

To use the search engine, simply call the searchCity function with the name of the city you want to search for. For example, searchCity("San Francisco") would return "The temperature in San Francisco is 20C and it is Sunny today." while searchCity("Paris") would return "Sorry, we could not find any weather data for Paris."

I assume you mean converting 285 degrees Fahrenheit to Celsius. To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and then multiply the result by 5/9.

Here's the formula:

javascript
 
 
Copy code
let fahrenheit = 285;
let celsius = (fahrenheit - 32) * 5/9;
console.log(celsius);

The answer is approximately 140.56 degrees Celsius.

Note that the formula works both ways, so you can convert Celsius to Fahrenheit by multiplying by 9/5 and then adding 32.

To get the temperature in your current location using an API, you can use the OpenWeatherMap API. You will need to sign up for a free account to obtain an API key. Once you have obtained the API key, you can then use the following example code in JavaScript to fetch the temperature data:

code
 
 
Copy code
const apiKey = "YOUR_API_KEY";
const apiEndpoint = "https://api.openweathermap.org/data/2.5/weather";

// Fetching temperature data
fetch(`${apiEndpoint}?appid=${apiKey}&q=${encodeURIComponent('YOUR_CITY')}&units=metric`)
  .then(response => response.json())
  .then(data => {
    console.log(`The temperature in ${data.name} is ${data.main.temp}°C`);
  })
  .catch(error => console.error(error))

Replace YOUR_API_KEY with the API key you obtained from OpenWeatherMap and YOUR_CITY with your city's name. This code will use the encodeURIComponent() function to make sure that the city name is properly URL-encoded. The data returned from the API call will include the temperature in degrees Celsius.

javascript
 
 
Copy code
// We can create an array of objects where each object contains information about a city, and one of those properties could be temperature. Here's an example:

let cities = [
  {name: 'Paris', country: 'France', population: '2.141 million', temperature: '17°C'},
  {name: 'London', country: 'United Kingdom', population: '8.9 million', temperature: '15°C'},
  {name: 'Berlin', country: 'Germany', population: '3.77 million', temperature: '12°C'}
];

// We can then loop through the array and log the temperature of each city:
cities.forEach(city => {
  console.log(city.temperature);
});

This will output:

code
 
 
Copy code
17°C
15°C
12°C

Note that the values for each city (other than Paris) are hypothetical and taken just as an example.
