// SizeOperator.cpp : main project file.
// Program : To implement sizeof operator
#include "stdafx.h"
#include<stdio.h>
#define sizeof_op1(val) ((char *)(&(val) + 1) - (char *)&(val))// for variable
#define sizeof_op2(type) ((type *)0) + 1//((type *) (10) + 1) - (type *) (10) // for type
using namespace System;
int main(array<System::String ^> ^args)
{
int i=0;
char ch = 'a';
float f = 1.00f;
printf("\nSize of int : %d %d",sizeof_op2(int),sizeof(int));
printf("\nSize of char : %d %d",sizeof_op2(char),sizeof(char));
printf("\nSize of float : %d %d",sizeof_op2(float),sizeof(float));
printf("\nSize of long : %d %d",sizeof_op2(long),sizeof(long));
printf("\nSize of short : %d %d",sizeof_op2(short),sizeof(short));
printf("\nSize of double : %d %d",sizeof_op2(double),sizeof(double));
printf("\nSize of long double : %d %d",sizeof_op2(long double),sizeof(long double));
printf("\nsize of int variable :%d %d",sizeof_op1(i),sizeof(i));
printf("\nsize of char variable :%d %d",sizeof_op1(ch),sizeof(ch));
