Sort the array in descending order

Posted on Apr 23, 2020

C program to sort the array in descending order.

Program

#include<stdio.h>
#include<conio.h>
#define MAX 50

void read_array(int a[MAX], int n)
{
    int i;
    for(i=0;i<n;i++)
    {
        printf("Element %d\t:",i+1);
        scanf("%d",&a[i]);
    }
}

void print_array(int a[MAX], int n)
{
    int i;
    for(i=0;i<n;i++)
    {
        printf("Element %d\t:%d\n",i+1,a[i]);
    }
}

void main()
{
    int arr[MAX];
    int i, j, n, temp;

    printf("Enter the number of elements in the array\t:");
    scanf("%d",&n);

    printf("Enter the elements of the array\n");
    read_array(arr, n);

    for(i=0;i<n;i++)
    {
        for(j=i+1;j<n;j++)
        {
            if(arr[i] < arr[j])
            {
                temp = arr[i];
                arr[i] = arr[j];
                arr[j] = temp;
            }
        }
    }

    printf("\nSorted array in descending order is\n");
    print_array(arr, n);

    getch();
}

Output

Enter the number of elements in the array       :8
Enter the elements of the array
Element 1       :56
Element 2       :45
Element 3       :12
Element 4       :89
Element 5       :74
Element 6       :52
Element 7       :36
Element 8       :45

Sorted array in descending order is
Element 1       :89
Element 2       :74
Element 3       :56
Element 4       :52
Element 5       :45
Element 6       :45
Element 7       :36
Element 8       :12
