7.2Inheritance
7.2.1 Introduction
The ability to use already created classes is one of the strengths of C++. If you have a ready made class, you can construct a new one using the existing characteristics. Inheritance is the ability to create a class using, or based on, another. The new or inherited class is also said to derive, or be derived, from the other class.
To start with inheritance, you should define a class. This means that it should have functionality, characteristics, and behaviors that other classes can use with little concerns as to how the class was built, but trusting that it can handle the desired assignment of a parent. To when creating the class, it must be made with ref instead of value. Here is an example:
public ref class CProperty
{
public:
int Bedrooms;
double Bathrooms;
int YearBuilt;
double Value;
};
