Answer 1

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

int generate_random_odd_numbers_between_min_and_max(int min, int max) {
    return (rand() % ((max - min + 1) / 2)) * 2 + min;
}

int main() {
    srand(time(NULL));
    
    int min = 7;
    int max = 39; 
    
    for (int i = 1; i <= 10; i++) {
        int n = generate_random_odd_numbers_between_min_and_max(min, max);
        printf("%d\n", n);
    }
    
    return 0;
