C Program to Sort Array in Descending Order using Standard Method

#include <stdio.h>
 
int main()
{
    int a[10000],i,n,j,temp;
   
    printf("Enter size of the  array : ");
    scanf("%d", &n);
    printf("Enter elements in array : ");
    for(i=0; i<n; i++)
    {
        scanf("%d",&a[i]);
    }
      
     
    for(i=0; i<n-1; i++)
    {
           
        for(j=0; j<n-i-1; j++)
        {
           if(a[j]<a[j+1])
           {
           	temp=a[j];
           	a[j]=a[j+1];
           	a[j+1]=temp;
		   }
 
        }
       
    }
    printf("\narray elements in descending order:\n ");
 
    for(i=0; i<n; i++)
    {
       printf("%d ",a[i]);
    }
    
 }

The result of the above c program; as follows:

Enter size of the  array : 5
Enter elements in array : 1 2 3 4 5
array elements in descending order:
 5 4 3 2 1 

C Program to Sort Array in Descending Order using Function

#include <stdio.h>
 
int sort(int *a,int n)
{ 
    int i,j,temp;
     for(i=0; i<n-1; i++)
    {
           
        for(j=0; j<n-i-1; j++)
        {
           if(a[j]<a[j+1])
           {
           	temp=a[j];
           	a[j]=a[j+1];
           	a[j+1]=temp;
		   }
 
        }
       
    }
    
    
       
 }
 print(int *a,int n)
{ 
   
    int i;
    for(i=0; i<n; i++)
    {
       printf("%d ",a[i]);
    }
    
       
 }
 
  
int main()
{
    int a[10000],i,n,key;
   
    printf("Enter size of the  array : ");
    scanf("%d", &n);
    printf("Enter elements in array : ");
    for(i=0; i<n; i++)
    {
        scanf("%d",&a[i]);
    }
     
   sort(a,n);
      print(a,n);
 
     
    
}

The result of the above c program; as follows:

Enter size of the  array : 5
Enter elements in array : 5 6 7 8 9
9 8 7 6 5
