Data stored in data members won t be accessible

Only public members will be accessible to be copied

Compiler will give out of memory error

Data stored in data members won t be accessible

It will not create the object (as parameterized constructor is used)

It will create the object (as the default arguments are passed)

It will not create the object (as the default constructor is not defined)

It will create the object (as at least some constructor is defined)
