Do While Loop

A do while loop runs the body once before checking the condition.

do_while_loop.c

#include <stdio.h>

int main(void) {
    int value = ;
    int visits = 0;

    do {
        visits++;
        value--;
    } while (value > 0);

    printf("visits=%d\n", visits);
    return 0;
}

#include <stdio.h>

int main(void) {
    int value = ;
    int visits = 0;

    do {
        visits++;
        value--;
    } while (value > 0);

    printf("visits=%d\n", visits);
    return 0;
}

#include <stdio.h>

int main(void) {
    int value = ;
    int visits = 0;

    do {
        visits++;
        value--;
    } while (value > 0);

    printf("visits=%d\n", visits);
    return 0;
}

do while `do { ... } while (condition);` checks after the first run.

at least once The body executes even when the condition starts false.
