Hints

while (1) loops until break.

Solution explanation

An infinite loop with a break is the natural shape for "repeat until done".

Show solution

#include <stdio.h>

int main() {
    int secret = 37, guess, tries = 0;
    while (1) {
        scanf("%d", &guess);
        tries++;
        if (guess < secret) {
            printf("higher\n");
        } else if (guess > secret) {
            printf("lower\n");
        } else {
            printf("correct in %d\n", tries);
            break;
        }
    }
    return 0;
}
