C Program to Sort a random array of n integers using Quick sort algorithm | DS - IProgramX

Q.  Sort a random array of n integers (accept the value of n from user) in ascending order by using recursive Quick sort algorithm.

Program

#include <stdio.h>
int main()
{
  int n, array[1000], c, d, t;

  printf("Enter number of elements\n");
  scanf("%d", &n);

  printf("Enter %d integers\n", n);

  for (c = 0; c < n; c++) {
    scanf("%d", &array[c]);
  }

  for (c = 1 ; c <= n - 1; c++) {
    d = c;

    while ( d > 0 && array[d-1] > array[d]) {
      t          = array[d];
      array[d]   = array[d-1];
      array[d-1] = t;

      d--;
    }
  }

  printf("Sorted list in ascending order:\n");

  for (c = 0; c <= n - 1; c++) {
    printf("%d\n", array[c]);
  }

  return 0;
}

Output:

Enter number of elements
5
Enter 5 integers
5
7
9
3
6
Sorted list in ascending order:
3
5
6
7
9
