C program to accept n number from user store these numbers into an array and sort the numbers of an array.

Write a C program to accept ‘n’ number from user, store these numbers into an array and sort the numbers of an array.

#include<stdio.h>
#include<conio.h>
void main()
{
  int n,a[20],i,j,temp;
  clrscr();
  printf("\n ENTER HOW MANY NO U WANT");
  scanf("%d",&n);
  printf("enter the elements\n");
  for(i=0;i<n;i++)
  {
   scanf("%d",&a[i]);
  }
  for(i=0;i<n;i++)
  {
    for(j=i+1;j<n;j++)
    {
      if(a[i]<a[j])
      {
  temp=a[i];
  a[i]=a[j];
  a[j]=temp;
      }
    }
   }
   printf("\nSORTED ARRAY ELEMENTS \n");
   for(i=0;i<n;i++)
   {
     printf("%d\t",a[i]);
   }
   getch();
  }
