Loops are control structures that enable repetitive execution of a block of code until a specific condition is met. They allow you to execute a set of statements multiple times, iterating over a sequence of instructions as long as the given condition holds true.


We have three types of looping statements:

  • For loop
  • While loop
  • Do-While loop

 

For loop:

It is an entry controlled loop.

It Contains three parameters-

for( initialization ; condition ; increment )

{

}

 

A program using nested loops to print the following pattern is as follows:

While loop:

It is also an entry controlled loop.

Here is a program to print the table of 50 using while loop


Do while loop:

It is an exit controlled loop.

Here is a program to find the sum of 10 numbers using do while loop
