Name of the object C++

is there a way to let the constructor of the object know its name?

I would like to have string myObject.name created by the constructor based on the actual name of the object. Is it possible? 

myClass Example;
//constructor creates an object with this name and i would like to have Example.name=="Example";

Thank you for your help!

Not very useful, but with a macro you can achieve something near:

#define CREATE( a, b ) a b(b)

int main()
{
   CREATE( myClass, example );
}

assuming of course that myClass has a constructor with a string as argument.

On the bottom line, I agree with the other answer, there really no point doing this.

There is no such inbuilt functionality. Although you can build one for yourself, following is the one way how you can achieve it.

    class myClass {
       std::string m_objectName;
    public:
       myClass(std::string name):m_objectName(name);
       std::string name()
       {
           return m_objectName;
       }
    };

Now create object like this:

myClass Example("Example");

There's no guarantee that it actually has a source name of any kind, so there's no sense in such a mechanism. And furthermore, tying your user display to the internal implementation details of your source code is a tremendously bad idea.

You, of course, can assign it whatever name you like that you think has whatever meaning you like.
