This article provides a comprehensive overview of polymorphism in C++ programming language. Concepts like virtual functions, pure virtual functions and others are covered with example programs.   Introduction   Polymorphism is of two types: 1) Compile-time polymorphism and 2) Run-time polymorphism as illustrated in the following figure:   Function Overriding   Following program demonstrates function […]

This article provides a comprehensive overview of inheritance in C++ programming language along with relevant example programs.   Introduction One of the main advantages of object oriented programming is reusability. Using already existing code is known as reusability. C++ supports reusability through inheritance which is creating a new class from already existing class.     […]

This article provides a comprehensive overview of operator overloading in C++ programming language along with example programs.   Introduction   While evaluating expressions, C++ compiler checks whether the operands are of normal types or user-defined types. If the operands are of built-in or normal type, it performs the regular operation. If the operands are of […]

This article provides a comprehensive overview of constructors and destructors in C++ programming language along with example programs.   Introduction Until now in our C++ programs, we are initializing the data members of a class by creating one or more member functions and passing values as parameters to those functions. We know that C++ considers […]

This article provides a comprehensive overview of classes and objects in C++ programming language along with example programs.   Introduction Object oriented programming paradigm makes it easy to solve real-world problems.       Syntax for declaring a class is as follows: class ClassName { access-specifier: type variable1; type variable2; …. type function1(params-list); type function2(params-list); […]

This article provides a comprehensive overview of functions in C++ programming language along with easy to understand example programs.   Introduction to functions While writing large programs, main() function will become quite complex to maintain and soon you will lose track of what is happening.   This is where functions will aid programmers.     […]

This article provides a comprehensive overview of arrays and strings in C++ programming language along with example programs.   Arrays Introduction     Elements in an array are stored in order and sequentially inside the memory.   Need for arrays Think that we have to store five values in a program. We can declare five […]

This article provides a comprehensive overview of C++ basic concepts along with easy to understand examples.   Learn more about C++ programming language.   Tokens   C++ program contains several elements and those are identified as tokens by a compiler.         Keywords cannot be used as identifiers in programs.       […]

This article provides a comprehensive overview of input and output in C++ programming language along with example programs.   Any program in a given programming language needs significant amount of input from the user and also needs to display to the output several times.   To support such I/O operations, C++ provides a library which […]

In this article we will look at introduction to C++. First we start with the history of C++ and move on to the basic structure of a C++ program.   Learn more about C++ programming language.   History of C++   Following are various applications of C++ language:   Structure of a C++ Program   […]
