random function problem

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;
}

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


when this exicutes i just keep getting 22 as number instead of another number. can some one help me

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;
