This means if there are two classes inheriting from an abstract class, both classes should provide the implementation of a pure virtual function; otherwise, they will become abstract. It ensures that the necessary function is implemented in every class. Enroll in Intellipaat’s C Programming ...
Whenever, there is a virtual function in the class, a v-table is constructed in the memory. The v-table has a list of addresses to the virtual functions of the class and pointers to the functions from each of the objects of the derived class. When a virtual function call is made, ...
Virtual functions are an integral part of polymorphism in C++. To learn more, check our tutorial onC++ Polymorphism. Example 1: C++ virtual Function #include<iostream>usingnamespacestd;classBase{public:virtualvoidprint(){cout<<"Base Function"<<endl; } };classDerived:publicBase {public:voidprint...

An inline function in C++ programming is a special type of function defined using the inline keyword. Instead of making a traditional call where control is passed to the function and then returned, an inline function's code is directly inserted into the place where the function is called. ...
PASCAL, C , BASIC, and COBOL are some of the procedural programming languages. C++, Java, C#, and Python are OOP languages. Check out our blog on What is Friend Function in C++? to learn more about C++ and its functions. Why are OOPs needed? The major reason why we need OOPs is co...
