How To Generate Random Numbers in C With a Range

In this tutorial, we are going to see how to generate random numbers in C with a range. The rand() function is used in C to generate a random integer. In the following code we have used rand() % 100 + 1 to generate random numbers between 1 and 100. So to generate random numbers between 1 and 10 use rand() % 10 + 1.
 

How To Generate Random Numbers in C With a Range

#include <stdio.h>
#include <stdlib.h>
 
int main() {
  int i, n;
 
  printf("10 random numbers in [1,100]\n");
 
  for (i = 1; i <= 10; i++) {
    n = rand() % 100 + 1;
    printf("%d\n", n);
  }
 
  return 0;
}

Output:

10 random numbers in [1,100]
