How to access the value of some variable using pointer

 In this article we will learn how to access the value of  any variable by using pointer . lets there is a variable X  and a pointer P .  For access the value of  x by using pointer P we have to Asterisk ( * ) operator. 

#include<stdio.h>

int main()

{

int x=10;

// pointer declaration

int *p;

// pointer initialization

p=&x;

printf("Value of X is %d\n",x);

printf("Address of the x is %u\n",&x);

printf("Address of X or Value of pointer P is %u\n",p);

printf("Value of X using pointer P %d\n",*p);

printf("Address of P is %u\n",&p);

return 0;

}

Output:-

Value of X is 10

Address of the x is 3315116764

Address of X or Value of pointer P is 3315116764

Value of X using pointer P 10

Address of P is 3315116768
