Computers and Technology
1 answer:
bekas [8.4K]3 years ago
5 0

Answer:

a. Object cannot be converted to Person

Explanation:

This program demonstrates polymorphism.

e.g., a Student IS a Person therefore you can call m() with a Student as well as a Person object.

The same goes for GraduateStudent.

However, and Object is not a Person, so the last call fails. This can be deducted by the type checking that happens at compile time.

True/False: If a function is legally prototyped to return an integer value, it can return a structure member that is an integer
sdas [7]
#1) If a function is legally prototyped to return an integer value, it can return a structure member that is an integer data type.
Answer: True. Any method that is not declared void must contain a return statement with a corresponding return value. The data type of the return value must match the method's declared return type; you can't return an integer value from a method declared to return a boolean.
