The size of a class can be changed simply by playing with the order of its members' declaration: struct A { bool a; int b; bool c; }; /*sizeof (A) == 12*/ On my machine, sizeof (A) equals 12. This result might seem surprising because the total size of A's members is only 6...

A virtual function is used where we want to allow the derived class to replace the implementation of the same function in base class. The compiler always calls the derived class function when called with object of the derived class or an object of base class holding the address of the derived class...

Introduction Memory allocation for objects is a tough issue, sometimes. Dynamically allocated memory has to be treated specially when one object is used to initialize another. In default constructor a bit wise copy is done when one object is assigned to another, leaving no room for separate...

Polymorphism is in short the ability to call different functions by just using one type of function call. It is a lot useful since it can group classes and their functions together. It is the most important part of Object-Oriented Programming. Polymorphism is the core of object-oriented programming...

Templates, which are sometimes called parameterized types, are mechanisms for generating functions and classes based on type parameters. By using templates, you can design a single class or function that operates on data of many types, instead of having to create a separate class for each type. ...

I posted a little about this in Sudoku Solving Program Using 'C' so that people could take a look at the solve part of the algorithm if they wanted. I was mid-development and this wasn't the part that was actually to change much except for a removal tweak of a magic number here and there. Since...

Introduction Many times you may have wondered how to return several values from a C++ function. I know it's easy for most of you when you know "how many" values your func is going to return. I have seen many people use std::pair to return two values from a func. But what about the case when you...
