What are people being taught if they think that these two concepts are the same thing? But a quick google search revealed that yes, many, many people are struggling to […]

I wrote some posts a while back on the principles of object oriented programming and have collated them into this 10 minute guide as a PDF file that you can download. It covers the main concepts of OOP and also has a simple example of polymorphism in C++. Get your copy here.

For example: int method(); int method(int); int method(int, double); Overriding describes the creation of a method in […]
