C++ Program To Display Size Of Different Datatype

Problem :- Write A C++ Program To Display Size Of Different Datatype. Here one thing noted down size of Datatype maybe depend upon your Operating System . Operating System You Are using maybe 32 Bit Or 64 Bit  

Logic :- For This Type of problem C++ Can Handle Easily .C++ have a "sizeof" Operator to find a size of any datatype  Follow Given A Syntax

Syntax :-  sizeof( datatype ) 

Replace Datatype by following datatype

int
float
double
long double
long long

There is another way to find the size of datatype by using pointer

Solution :- 

#include<iostream>
#include<math.h>
using namespace std;
int main()
{
 cout<<"size of int "<<sizeof(int)<<endl;
 cout<<"size of float "<<sizeof(float)<<endl;
 cout<<"size of double "<<sizeof(double)<<endl;
 cout<<"size of long "<<sizeof(long)<<endl;
 cout<<"size of long double "<<sizeof(long double)<<endl;
 cout<<"size of long long int "<<sizeof(long long int)<<endl;
 cout<<"size of long long "<<sizeof(long long)<<endl;


}
