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