C Programs - Loops

While programming we usually come across a requirement where we want to execute a block of code repetitively.
Loops help us to achieve such functionality.

A loop executes a block of code until the condition given to it becomes false.

Basically there are three types of loop in C language

1. for loop
2. while loop
3. do-while loop
