Class + Main() = error cout?

[Lincoln_Poh]

Can someone help me out with this problem? Basically, I have a "Classes" class inside one of my file. Below is the code:

//Classes Class.hpp
#include <iostream>
#include <string>

using namespace std;

class Classes
{
    public: string favouriteLanguage;

    public: Classes() //Classes' constructor
    {
        cout<< "Classes' has been executed"<< endl;
    }

    public: void Display()
    {
        cout<< "I love "<< favouriteLanguage<< endl;
    }
};

The class which Ive created included one Class constructor. Now, I created a console application which link to that "Classes.hpp". Below is the codes for the main():

//instantiate object from banner class
#include "Classes.hpp"

int main()
{
    Classes a;
    Classes b;

    a.favouriteLanguage = "C++";
    a.Display();

    b.favouriteLanguage = "Java";
    b.Display();

    std::cout<< "The value that dominates all is "<< b.favouriteLanguage<< endl;

    return 0;
}

Now, when I compile, the constructor should be automatically executed right? That's what my program did. It executed, but TWICE?~! Can someone help me out? When I compile and build it, the "Classes" constructor executed twice...I want it to be executed once only. Thanks in advance for the help.

The constructor is called on the creation of each instance of the class at runtime, not at compilation. You create two different instances of your class, a and b, so of course the constructor runs twice.

A constructor is executed once for each instance created of the object, in this case for both a and b. If you want something to only execute once per program, don't use a constructor.

Oh my, I understand now! Thanks guys

BTW, you don't need to put public: before everything in the class; just once is fine. This ain't Java.

Ya, public/protected/private are sections. After the keyword, every function/variable will be public, protected or private until the end of the class or another keyword.

Also, using statements in header files are a big no-no. Explicitly qualify access to elements of namespace std instead.
