C Program to arrange the elements in an array in Descending Order

This is a C Program which arranges all the elements in an array in descending order.

Here initially first element in array and its next element are compared array[0] and array[1] , if array[1] is less, then the values are swapped, and the process continues with 2 and 3 elements and son on until the end of array is reached.

Finally the obtained array is the sorted array in descending order.

PROGRAM :

#include<stdio.h>
#include<conio.h>
int main()
{
    int i,j,no,temp;

    printf("\nEnter the no of Elements: ");
    scanf("%d", &no);
    int arr[no];
    for(i=0;i<no;i++)
    {
        printf("\n Enter Element %d: ", i+1);
        scanf("%d",&arr[i]);
    }

    for(i=0;i<no;i++)
    {
        for(j=i;j<no;j++)
        {
            if(arr[i] < arr[j])
     {
                temp=arr[i];
                arr[i]=arr[j];
                arr[j]=temp;
            }
        }
    }

    printf("\nSorted array:");
    for(i=0;i<no;i++)
        printf("\t%d",arr[i]);

    return 0;
}

OUTPUT :
