Chapter 10, Problem 4AW

Program Plan Intro

Overriding:

• • Method overriding means having multiple methods with same name and same signature in combination of base class and derived class.
• • The derived class method overrides the base class method when method in derived class has same name as method in base class.
• • For overriding the properties, the base class properties can be overridden in similar way that base class methods can be overridden.
  • ○ The virtual property is a property that appears in a base class but expects to be overridden in a derived class.
  • ○ In base class, programmer need to write “virtual” keyword in base class method declaration and “override” keyword in derived class method declaration.
