Description

Generates a list of 100 random numbers in the range 1-10 in sorted decreasing order

Demo Code

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

void random_ints(int *int_array);

int main(void){
  int int_array[100];
  random_ints(int_array);

  for (int i = 0; i < 100; i++){
    printf("%2d ", int_array[i]);
    if (i % 20 == 19)
      putchar('\n');
  }/* ww  w . jav a 2  s. c o m*/

  putchar('\n');
  return 0;
}

void random_ints(int *int_array){
  int tmp;

  for (int i = 0; i < 100; i++)
    int_array[i] = rand() % 10 + 1;
  
  // sort array in decreasing order
  for (int i = 0; i < 99; i++)
    for (int j = i + 1; j < 100; j++)
    {
      if (int_array[i] < int_array[j])
      {
        tmp = int_array[i];
        int_array[i] = int_array[j];
        int_array[j] = tmp;
      }
    }
}
