Basic Example to Understand Pointers

This is basic example i created to understand Pointers

code:

Basic Example to Understand Pointer's*/
#include<stdio.h>
#include<conio.h>
void main()
{
 int a=20,*p,**k;
 clrscr();
 p=&a;
 k=&p;  /* here *p is pointer of a & **k of *p */
 printf("\n1.Value of a=%d",a);
 printf("\n\n2.Address of a=%u",&a);
 printf("\n\n3.Value of p=%u",p);
 printf("\n\n4.Value of a=%d",*p);
 printf("\n\n5.Address of pointer p=%u",&p);
 printf("\n\n6.Value of k=%u",k);
 getch();
}

Output:

Code Analysis:

Here we took 1 variable a whose value is 20

*p is a pointer of a & **k is pointer of *p

Put this in mind

Value of a=20

Address of a=65524

Value of p=65524(Address of a=65524)

Address of p=65522

Value of k=65522(Address of p=65522)
