C Program to Access Address of Variable using Pointer

#include<stdio.h>
void main( )
{
int i = 3 ;
printf("\nAddress of i = %u", &i ) ;
printf("\nValue of i = %d", i ) ;
printf("\nValue of i = %d", *( &i ) ) ;
}

Output:

Address of i = 65524
Value of i = 3
Value of i = 3

Explanation :

Variable ‘i’ is declared of type integer in the program , now suppose the integer variable can have value 3 stored inside it and it has address 65524.

Suppose we want to access the address of the variable i then we can use ampersand operator to find the address of the variable.

&i

and whenever we use ampersand and value at operator together then we will get actual value of the variable.

* (&i) = Value at (&i)
       = Value at (65535)
       = 3

Values of Variable and Address

Variable Expression	Meaning of the Variable	Value
&i	Address of i	65524
i	Value of variable i	3
*( &i )	Value of variable i	3
