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:
do {
// The code block
} while (condition);
The example of using do/while loop:
12345int 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:
12345int i = 0; do { cout << i << endl; i++; } while (i < 0);
