Question

After the initial construction of both, what does the following code invoke?

a) Default constructor
b) Copy constructor
c) Assignment operator
d) None of the above

Answer 1

The code will invoke either the copy constructor or the assignment operator, depending on whether a new object is being created as a copy of another, or an existing object is being assigned the value of another.

Step-by-step explanation:

After the initial construction of both, the code will invoke the copy constructor if it is a statement like Object newObj(existingObj), where existingObj is an instance of a class and newObj is being created as a copy of existingObj. Alternatively, it will invoke the assignment operator if the statement is similar to existingObj = newObj, where both objects have already been constructed, and you are assigning the value of one to another.
