>Description:
In the attached program first used constructor of class A is copy constructor, i.e. copy constructor is called before any class objects are initialized (so it tries to copy uninitialized object).

The program prints which constuctor of A is called, and the output look like:

Constructor A(const A&)
Constructor A(const A&)
Constructor A(const A&)
Constructor A()
