Write a program to show the size of char type variable and use of pointers in c language.

#include<stdio.h>

#include <stdlib.h>

int main()

{

char a, b, c, *p, *q, *r;

p = &a;

q = &b;

r = &c;

printf("adress of a is = %d \n",&a);

printf("adress of b is = %d \n",&b);

printf("adress of c is = %d \n\n",&c);

printf("adress of *p is = %p \n",p);

printf("adress of *q is = %p \n",q);

printf("adress of *r is = %p \n",r);

printf("size of a = %d bytes\n", sizeof(a));

printf ("Size of b = %d bytes\n",sizeof (b));

printf ("Size of c = %d bytes\n",sizeof (c));

printf ("Size of  *p = %p bytes\nSize of char *q = %p bytes\nSize of *r = %p bytes\n",sizeof (*p),sizeof (*q),sizeof (*r));

system("PAUSE");
