#include <stdio.h>
#include <string.h>
#include <time.h>
int main () {
    char s[] = "4813,4810,4811,4812";
    char* src[100];
    int n = 0;
    char * p = strtok(s, ","); 
    while (p)
    {       
        src[n++] = p;
        p = strtok(NULL, ",");
    }
    srand(time(NULL));
    char * result = src[rand() % n];
    printf("%s\n", result);
    return 0;
