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.

- Using a for statement
- Using a while statement
- Using a do-while statement
Each of these methods is discussed in the following pages.
