Union in C Programming

A union in C programming is a user defined data type which may hold members of different sizes and type. Union uses a single memory location to hold more than one variables. However, only one of its members can be accessed at a time and all other members will contain garbage values. A structure is a convenient tool for handling a group of logically related data items. Structure help to organize complex data is a more meaningful way. It is powerful concept that we may after need to use in our program Design.

Basic Data Types in C Programming

C language provides a standard and minimal set of basic data types. Sometimes these are called primitive data types. More complex data structures can be built up from these basic data types. Data types specify how we enter data into our C programs and what type of data we use for different operations. C has some predefined set of data types to handle various kinds of data that we can use in our program.

Advanced C++ Inheritance Techniques for Effective Object-Oriented Programming

In Object Oriented Programming Inheritance is the process by which objects of one class acquire the properties and functionality of objects of another class. In the last tutorial on inheritance in C++ we developed a model using modes of transportation to illustrate the concept of inheritance. In this article we will use that model to illustrate some of the finer points of inheritance and what it can be used for.

Inheritance in C++

The principle of inheritance is available with several modern programming languages and is handled slightly differently with each. C++ allows you to inherit all or part of the members and methods of a class, modify some, and add new ones not available in the parent class. You have complete flexibility, and as usual, the method used with C++ has been selected to result in the most efficient code execution.
