Coding is the process of writing instructions for a computer to follow,
using a programming language. It's also known as computer programming.
Coding is the composition of sequences of instructions, called programs,
that computers can follow to perform tasks. It involves designing and
implementing algorithms, step-by-step specifications of procedures, by
writing code in one or more programming languages. Programmers typically
use high-level programming languages that are more easily intelligible
to humans than machine code, which is directly executed by the central
processing unit. Proficient programming usually requires expertise in
several different subjects, including knowledge of the application
domain, details of programming languages and generic code libraries,
specialized algorithms, and formal logic.
