At a Glance
Loops are programming elements which repeat a portion of code for a number of times till
the desired process is complete.
While, For and Nested are the different types of loops.
A looping condition must get false at a certain point of time, else the block of code will enter
in an infinite loop. For this it is important to define an exit criterion for the loop.
