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

int main() {
    int len = 10;
    char key[len + 1];
    srand(time(NULL));

    int i;
    for (i = 0; i < len; ++i) {
        key[i] = 33 + rand() % (125 - 33 + 1);  // generate characters from 33-125
    }

    key[i] = '\0';
    printf("The generated key is %s\n", key);
    return 0;
}
