Sorting Using Pointer

In this program we are going to sort an array using pointer. Following is the example to implement it.

Example :

#include <stdio.h>
#include <conio.h>
#include <alloc.h>
void main()
{

//Declaration of variables
int n,*p,i,j,temp;
clrscr();
printf("\nEnter n: ");
scanf("%d",&n);

//Memory allocation to pointer
p=(int *) malloc(n*2);
if(p==NULL)
{
printf("\nMemory allocation failed");
}

printf("\nEnter %d numbers",n);
for(i=0;i<n;i++)
{
scanf("%d",p+i);
}

//Accessing array for sorting
for(i=0;i<n;i++)
{
for(j=0;j<n;j++)
{
if(*(p+i)<*(p+j))
{
temp=*(p+i);
*(p+i)=*(p+j);
*(p+j)=temp;
}
}
}

//Printing sorted array
printf("\nTHE SORTED NUMBERS ARE:\n");
for(i=0;i<n;i++)
printf("%d ",*(p+i));
getch();
}
