Student Marksheet using Multiple inheritance

Write a C++ Program display Student Marksheet using Multiple inheritance. Here’s a Simple C++ Program display Student Marksheet using Multiple inheritance in C++ Programming Language.

What are Inheritance in C++ ?

• Inheritance allows us to define a class in terms of another class, which makes it easier to create and maintain an application. This also provides an opportunity to reuse the code functionality and fast implementation time.
• When creating a class, instead of writing completely new data members and member functions, the programmer can designate that the new class should inherit the members of an existing class. This existing class is called the base class, and the new class is referred to as the derived class.
• The idea of inheritance implements the is a relationship. For example, mammal IS-A animal, dog IS-A mammal hence dog IS-A animal as well and so on.

Types of Inheritance : :

There are different types of inheritance : :

• Single Inheritance
• Multiple Inheritance
• Multilevel Inheritance
• Hierarchical Inheritance
• Hybrid (Virtual) Inheritance
