What is loop

Answer 1

Suppose you have some statements in a code which should be executed multiple times. Instead of writing those statements as many times as needed, you can use a loop and set a condition so that those statements will be executed as many times as needed and stops when the condition becomes false.

Answer 2

"A loop statement allows us to execute a statement or group of statements multiple times."
