C++ do while loops

C++ do while loop is similar to the while loop, but it always executes a code block at least once and so on as long as the condition is true. This is an exit-controlled loop. This tutorial will teach you how to use the do while loop in C++.

The basic format of the do while loop statement is:

Syntax:

do
{
   statement(s);
}
while( condition );

Example C++ program to demonstrate the do while loop:

Example:

#include <iostream>
using namespace std;

int main ()
{
    /* local variable Initialization */
    int n = 1,times=0;

    /* do-while loops execution */
    do
    {
        cout << "C++ do while loops: " << n <<endl;
        n++;
    }
    while( n <= times );
    
    return 0;
}

Program Output:
