Computer program and programming

A computer program is a set of instructions, written in a programming language in a logical order, that makes the computer perform a specific task.

Computer programming is the process of designing, writing, testing, debugging and maintaining programs. It includes analysing the problem, designing an algorithm, coding it in a language such as C, and testing it until it produces correct results.

Example: a C program that reads two numbers and prints their sum is a program; the activity of developing it is programming.
