Introduction to Repetition in Programs

In real-life, we often repeatedly perform specific tasks until we achieve a particular goal. For instance, while washing the dishes, we take a soiled dish, scrub it with a dishcloth and soap, rinse it with water, and place it in a rack. We keep doing this until all the dishes are done. Since we want our computers to mimic such behavior when solving problems, repetition is an integral tool in programming.

In computer programs, a sequence of instructions that executes until a condition becomes false is called a loop.
