FAQs on C++ Programming Tutorials - Inheritance

Question 1

1. What is inheritance in C programming?

Accepted Answer

Ans. Inheritance in C programming is a concept that allows a class to inherit the properties and behaviors of another class. The class that is being inherited from is called the base class or parent class, and the class that inherits from it is called the derived class or child class. This allows the derived class to reuse code from the base class and add its own specific functionality.

Question 2

2. How is inheritance implemented in C programming?

Accepted Answer

Ans. Inheritance in C programming is implemented using the concept of structures. The derived structure includes the base structure as its first member, which allows it to access the members of the base structure. By doing this, the derived structure inherits all the properties and behaviors of the base structure.

Question 3

3. What are the advantages of using inheritance in C programming?

Accepted Answer

Ans. Using inheritance in C programming provides several advantages, including code reusability, modularity, and extensibility. It allows the programmer to reuse existing code from the base class, reducing the need for redundancy. It also promotes modularity by separating different functionalities into different classes. Additionally, it enables the derived class to inherit the properties and behaviors of the base class and add new functionality specific to itself, thus providing extensibility.

Question 4

4. Can a derived class inherit multiple base classes in C programming?

Accepted Answer

Ans. No, in C programming, a derived class can only inherit from a single base class. Multiple inheritance, where a derived class inherits from multiple base classes, is not supported in C programming. However, you can achieve similar functionality by using composition, where a class can contain objects of other classes as members.

Question 5

5. How does inheritance affect the access control in C programming?

Accepted Answer

Ans. Inheritance in C programming affects the access control of the members of the base class in the derived class. If the base class has private members, they are not directly accessible in the derived class. However, protected members of the base class are accessible in the derived class. Public members of the base class remain accessible in the derived class as well.
