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 );Figure - Flowchart of the do while loop:
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:
