A do…while loop is used when the statements are to be executed at the beginning and later the condition to be checked. Hence there is at least one chance that the given statements are executed.

Syntax:

do

{

statements;

.

.

}

while(condition);

Example program

//To print natural numbers from 1 – 10

#include<iostream.h>

#include<conio.h>

void main()

{

int i=1;

do

{

cout<<i<<endl;

i++;

}

while(i<=10);

getch();

}

Output:

1

2

3

4

5

6

7

8

9

10
