C and C++ / Functions and Classes A function is an assignment or a task that must be performed to complement the other part of a program. There are two kinds of functions: those supplied to you and those you will be writing. The functions that are supplied to you are usually in three categories: those built-in the operating system, those written in C++ and those supplied with your programming environment. The use of these functions is the same regardless of the means you get them; you should know what a function looks like, how to create one, what functions are already available, where they are located, and what a particular function does, how and when to use it.

C and C++ / Functions and Classes Until now, in all the functions we have seen, the arguments passed to the functions have been passed by value. This means that when calling a function with parameters, what we have passed to the function were copies of their values but never the variables themselves. Site: www.cplusplus.com

C and C++ / Functions and Classes Functions are bits of code that the program jumps to in order to do certain tasks. The main function holds the main code (the code that is executed first) and where the other functions are called from. Variables can be passed into and returned from a function. Site: www.olate.co.uk

C and C++ / Grapics The simple fact that OpenGL is only a graphics API means that any user interaction, or things like screen and window issues needs to be handled by the operating system. Most operating systems come with a set of extensions that tie OpenGL together with user interaction and window management. This tends to make our lives a little bit easier, but only if we know how to take advantage of this option. In Windows this set of functions are called the wiggle functions. Each of these functions is prefixed with wgl. Site: www.cprogramming.com

C and C++ / Functions and Classes Inline functions are not very important, but it is good to understand them. The basic idea is to save time at a cost in space. Inline functions are a lot like a placeholder. Once you define an inline function, using the 'inline' keyword, whenever you call that function the compiler will replace the function call with the actual code from the function.

C and C++ / Pointers and References Pointers to Member Functions are one of C++'s more rarely used features, and are often not well understood even by experienced developers. This is understandable, as their syntax is necessarily rather clumsy and obscure. While they do not have wide applicability, sometimes member function pointers are useful to solve certain problems, and when they do apply they are often the perfect choice, both for improved performance and to make the code sensible.

C and C++ / Getting Started This tutorial is going to cover the basics of Visual C++. I will be covering alot of the basics, so this should be a good start to anyone wanting to learn C#. I could go into more details on all the functions, classes, objects ect. but that is another article for another time. Site: www.allsyntax.com

C and C++ / Grapics In this lesson I shall introduce several functions and show you actual OpenGL rendering in a program. Prior to showing you the code, however, I want to go over a few things with you. This will give you a better understanding of what is going on when you do see the code, so you don't stare at the screen wondering what you're looking at. So, on with the show.
