5: Program to check size of data types

#include<iostream>

using namespace std;
main(){
    int a;
    cout<<"The size of int is " <<sizeof(a)<<endl;

    float b;
    cout<<"The size of float is " <<sizeof(b)<<endl;

    char c;
    cout<<"The size of char is " <<sizeof(c)<<endl;

    double d;
    cout<<"The size of double is " <<sizeof(d)<<endl;

    bool e;
    cout<<"The size of bool is " <<sizeof(e)<<endl;

    return 0;
}

Output:

    The size of int is 4      
    The size of float is 4    
    The size of char is 1      
    The size of double is 8    
    The size of bool is 1

Thus:

    The size of int is 4 byte      
    The size of float is 4 byte    
    The size of char is 1 byte     
    The size of double is 8 byte   
    The size of bool is 1 byte
