_____________________________________________________________
A program for SizeOf() operator
#include<iostream>
using namespace std ;
int main () {
int a;
float b;
char c;
double d;
cout<<"size of integer = " <<sizeof(a) <<endl;
cout <<"size of float = " <<sizeof(b) <<endl;
cout<<"size of char = " <<sizeof(c) <<endl ;
cout<<"size of double = " <<sizeof(d) <<endl;
return 0 ;
}
_____________________________________________________________
Output :-
size of integer = 4
size of float = 4
size of char = 1
size of double = 8
