/*
A loop statement allows us to execute a statement or group of statements multiple times
1.While Loop:
"Repeats a statement or group of statements while a given condition is true.
It tests the condition before executing the loop body. "
2.For Loop:
"Execute a sequence of statements multiple times and
abbreviates the code that manages the loop variable. "
3.Do-While Loop:
"Like a while statement, except that it tests the condition at the end of the loop body. "
