Loops in C — while, do-while, and for Loops

A Loop is a control structure that repeats a block of code as long as a specified test condition evaluates to True. Each repetition of the loop is called an Iteration.

Every loop in C requires three essential components:

1. Initialization: Setting the starting value of a loop counter variable.

2. Condition / Test: The boolean expression checked before or after each repetition.

3. Update (Increment/Decrement): Modifying the counter so the loop eventually terminates.
