how to find name of object which is created on heap using new keywords in c++?
Suppose i have a class and create object of this class in main. so what will be the name of object which is pointed by pointer:

class A
{
A(){}

};
int main()
{
A *ptr=new A();
//here object will create and allocate memory which is
//assigned to pointer ptr, so i would like to know name
//of the object created through A()

}

It doesn't have a name. It doesn't need one, because nothing will ever use it - instead it has a reference or address which is stored in the variable and which is used by the system to identify the object in future.

If you like, it's like a currency note: a £5 note is just like all the other £5 notes, except it has a unique serial number (which is in effect the reference). Under normal circumstances you don't worry (or even look!) at the serial number as they are all worth the same amount of money. The serial number (reference) is there so that officials (the system) can uniquely identify the note (instance) if they need to.

Solution 2

There is no support for object class names in the C++ standard. But most frameworks provide an object class that supports names like the MFC CObject Class[^] with the member function CObject::GetRuntimeClass[^] and the Qt QObject Class[^].

To use them derive your class from those object classes.
