I want to create fast new random number between 0 and 9. For this modified a code that I found there:
Why do I always get the same sequence of random numbers with rand()?
and integrated it into a loop

The output I get is

Random fast seeded: 1
Random fast seeded: 1
Random fast seeded: 1
Random fast seeded: 1
Random fast seeded: 1
Random fast seeded: 1
Random fast seeded: 1
Random fast seeded: 1
Random fast seeded: 1
Random fast seeded: 1

Instead I would like to get something like:

Random fast seeded: 2
Random fast seeded: 8
Random fast seeded: 4
Random fast seeded: 7
Random fast seeded: 3
Random fast seeded: 1
Random fast seeded: 3
Random fast seeded: 5
Random fast seeded: 1
Random fast seeded: 9

Here is the code

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


int main ()
{
  struct timespec ts;
  for (int i = 0; i<10; i++){
    clock_gettime(CLOCK_MONOTONIC, &ts);
    srand((unsigned int)ts.tv_nsec);
    printf ("Random fast seeded: %d\n", rand()%10);
  }
  return 0;
}

What am I doing wrong?

>Solution :

Place these two statements

clock_gettime(CLOCK_MONOTONIC, &ts);
srand((unsigned int)ts.tv_nsec);

before the for loop.
