Question

Write a C program for sorting using pointer

Answer 1

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(); }
