displaying how float, double and long double works in c++

 #include<iostream>

using namespace std;

int main()

{

    float a=3.14;

    long double b=23.99;

    cout<<"The size of 3.14 is:"<<sizeof(3.14)<<endl;//by default f is treated as double

    cout<<"The size of 3.14f is:"<<sizeof(3.14f)<<endl;

    cout<<"The size of 3.14F is:"<<sizeof(3.14F)<<endl;

    cout<<"The size of 3.14l is:"<<sizeof(3.14l)<<endl;

    cout<<"The size of 3.14L is:"<<sizeof(3.14L)<<endl;

    return 0;

}
