10- a) What construct a programming language requires to support Polymorphic Variables?

b) When does the binding of Polymorphic variables to their values can happen? c) Use the code in question 9-c (above) to write an example of a polymorphic variable. (Your example does not have to completely follow the C++ syntax. What is important is being able to show the concept of polymorphic variables in your example)

3- a) What is the constructor of a class?

b) In some programming languages the class constructor must have a specific name while in some other languages, the class constructor can have any name. Describe the cons and pros of each approach.
