How to generate a random integer in a range (min...max) in C

Answer 1

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int get_random_in_range(int min, int max) {
    return min + rand() % (max - min + 1);
}

int main() {
    // Seed the random number generator
    srand(time(0));

    int min = 3, max = 14;

    for (int i = 0; i < 20; i++) {
        int randomNumber = get_random_in_range(min, max);
        printf("%d\n", randomNumber);
    }

    return 0;
}
