Introduction This article talks about size of a class with all possible scenarios like having simple data (with and without structure padding), virtual functions, Replicated and Shared Multiple Inheritance etc. Background Size of a class object is nothing but it's non-static member data +...

Constructors are functions with the same name as the class. They are used to create the instance of a class. They are provided default by the compiler. But still user can have his/her own constructor declared. We can have a constrctor with a single parameter and use this kind of constructor for...

Introduction This article talks about Enumerated Data Types and set of guidelines in using them. Background Definition: An Enumerated Type is a user defined data type that maps set of names to numeric values called Enumerators. Enums are generally used when we know all the possible...

Original Non English Version here. For simple applications, it's enough just to rely on automatic memory management through local variables. But once the data become larger, it is no longer imperative to request memory from the heap and manage. Content Function Families Allocators ...

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...

Being an experienced C/C++ developer, sometimes there are modules in which the code layer which interact with the system is written in C while the layer above it is written in C++. Have you ever thought of how these two layers (one written in C and other in C++) interact? What if we want to call a...

There are three techniques used to pass variables into a C or C++ functions. Pass by value C/C++ Pass a pointer by value C/C++ Pass by reference C++ only Pass by value The function receives a copy of the variable. This local copy has scope, that is, exists only within the function....

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...

One benefit of C++ over C is its exception handling system. An exception is a situation in which a program has an unexpected circumstance that the section of code containing the problem is not explicitly designed to handle. In C++, exception handling is useful bcause it makes it easy to separate...

Certain applications need to invoke startup functions that run before the main program starts. For example, polling, billing, and logger functions must be invoked before the actual program begins. The easiest way to achieve this is by calling these functions from a constructor of a global object....

The Input/Output system in C++, holds information about the result of every I/O operation. The current status is kept in an object from type io_state, which is an enumerated type (just like open_mode) that has the following values: godbit -> No errors. eofbit -> End of file has been reached...
