Do/While Loop

As an alternative to while loop you can use do/while loop. The difference is that the do/while loop will execute the code in the block once before checking if the condition returns true.

Syntax:

The example of using do/while loop:


              12345
            
int i = 0;
do {
    cout << i << endl;
    i++;
} while (i < 3);

The first iteration will be firstly executed and i becomes 1. By the third iteration, i becomes 3 and the condition returns false after that, and do/while loop stops.

Pay attention, that the first iteration will be executed even if the condition is always false:


              12345
            
int i = 0;
do {
    cout << i << endl;
    i++;
} while (i < 0);

Everything was clear?
