WAP to calculate the size of integer, character, float , double datatype

#include<iostream.h>

#include<conio.h>

void main()

{

clrscr();

cout<< " \nSize of character = " << sizeof(char);

cout<< " \nSize of integer = " << sizeof(int);

cout<< "\n Size of float = " << sizeof(float);

cout<< "\n Size of double = " << sizeof(double);

getch();

}

ALTERNATIVELY,

#include(iostream.h)

#include(conio.h)

void main()

{

clrscr(); 

int n;

float f;

char c;

double d;

cout<< " \nSize of character= " << sizeof(c);

cout<< " \nSize of integer = " << sizeof(n);

cout<< "\n Size of float = " << sizeof(f);

cout<< "\n Size of double = " << sizeof(d);

getch();

}
