What is public, protected, private? C++

✍: Guest

A

Public, protected and private are three access specifiers in C++.
Public data members and member functions are accessible outside the class.
Protected data members and member functions are only available to derived classes.
Private data members and member functions can’t be accessed outside the class. However there is an exception can be using friend classes.

What is polymorphism? C++
What is polymorphism? C++ Polymorphism is the idea that a base class can be inherited by several classes. A base class pointer can point to its child class and a base class array can store different child class objects. 2012-02-01, 2966👍, 0💬

What do you mean by inline function?
What do you mean by inline function? The idea behind inline functions is to insert the code of a called function at the point where the function is called. If done carefully, this can improve the application's performance in exchange for increased compile time and possibly (but not always) an increa... 2012-01-27, 2869👍, 0💬

What are the advantages of inheritance?
What are the advantages of inheritance? It permits code reusability. Reusability saves time in program development. It encourages the reuse of proven and debugged high-quality software, thus reducing problem after a system becomes functional. 2012-01-26, 2783👍, 0💬
