pointer

pointer:

              A pointer is a variable which contains the address in memory of another variable. We can have a pointer to any variable type.

 The indirection or difference operator * gives the contents of an object pointed to by a pointer.
 The unary or monadic operator & gives the address of a variable.

To declare a pointer to a variable do:

syntax:

   int *pointer;

Example :

#include<stdio.h>
#include<conio.h>
void main( )
{
int i;
clrscr( );
printf("The value of the i is :",*i);
getch();
}

OUTPUT:
The value of the i is : 1053

Explanation :

Here the output will be 1053 because it shows the output as it address,not it's value.
