Sample Solution:

C Code:

#include <stdio.h>

void main()
{
    int arr1[100];
    int n, i, j, tmp;
	
	
       printf("\n\nsort elements of array in descending order :\n");
       printf("----------------------------------------------\n");	

    printf("Input the size of array : ");
    scanf("%d", &n);

       printf("Input %d elements in the array :\n",n);
       for(i=0;i<n;i++)
            {
	      printf("element - %d : ",i);
	      scanf("%d",&arr1[i]);
	    }
    for(i=0; i<n; i++)
    {
        for(j=i+1; j<n; j++)
        {
            if(arr1[i] < arr1[j])
            {
                tmp = arr1[i];
                arr1[i] = arr1[j];
                arr1[j] = tmp;
            }
        }
    }

     printf("\nElements of array is 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:
