The versatility of the computer lies in its ability to perform a set of instructions repeatedly. This involves repeating some portion of the program either a specified number of times or until a particular condition is being satisfied. This repetitive operation is done through a loop control instruction
There are three methods by way of which we can repeat a part of a program. They are:

(a) Using a for statement

(b) Using a while statement

(c) Using a do-while statement
