PHP Code:

---

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

int random(int num);

main()
{
     while(1)
     {
             
     int timer = time(NULL);
     int variable[100];
     int i=0, j=0;
     
     
     sleep(1);
     srand(timer);
     
     
     variable[i] = random(23);
     printf("Random #: %d\t", variable[i]);     
     scanf("%f", &variable);
     }
     return;
}

{
    return((rand()/(RAND_MAX+1.0))*num);
}

You should call srand only once, not on every loop iteration.

And this is explained in the FAQ - check it out!;)

main() - read FAQ: main() / void main() / int main() / int main(void) / int main(int argc, char *argv[])

int i=0, - do you realize that having this inside the loop you are acessing the same variable[0] member on every iteration of the loop?

Code:

---

scanf("%f", &variable);

---

variable is integer array - what is this code should do? check the crash resistence of your system?

return; - main returns int
use

Code:

---

return 0;
