# C Exercises: Sort elements of an array in descending order

## C Array: Exercise-12 with Solution

Write a program in C to sort the elements of the array in descending order.

Visual Presentation:

Sample Solution:

C Code:

#include <stdio.h>

void main()
{
int arr1[100];
int n, i, j, tmp;

// Prompt user for input
printf("\n\nSort elements of array in descending order:\n");
printf("----------------------------------------------\n");
printf("Input the size of array : ");
scanf("%d", &n);

// Input elements for the array
printf("Input %d elements in the array :\n", n);
for (i = 0; i < n; i++)
{
printf("element - %d : ", i);
scanf("%d", &arr1[i]);
}

// Sorting elements in descending order using the Bubble Sort algorithm
for (i = 0; i < n; i++)
{
for (j = i + 1; j < n; j++)
{
if (arr1[i] < arr1[j])
{
// Swap elements if they are in the wrong order
tmp = arr1[i];
arr1[i] = arr1[j];
arr1[j] = tmp;
}
}
}

// Print sorted elements in descending order
printf("\nElements of array are sorted in descending order:\n");
for (i = 0; i < n; i++)
{
printf("%d  ", arr1[i]);
}
printf("\n\n");
}

Sample Output:

sort elements of array in descending order :
----------------------------------------------
Input the size of array : 3
Input 3 elements in the array :
element - 0 : 5
element - 1 : 9
element - 2 : 1

Elements of array is sorted in descending order:
9  5  1
