Turbo C graphics Programming

To start with graphics programming, Turbo C is a good choice. Even though DOS has its own limitations, it is having a large number of useful functions and is easy to program. To implement graphics algorithms, To give graphical display of statistics, To view signals from any source, we can use C graphics. Here is a article to start programming with Turbo C. 'Run and Learn' is our method. We have used source codes throughout the explanations. Just execute them to understand what is happening.

Turbo C has a good collection of graphics libraries. If you know the basics of C, you can easily learn graphics programming. To start programming, let us write a small program that displays a circle on the screen. /* simple.c example 1.0 */ #include #include void main() { int gd=DETECT, gm; initgraph(&gd, &gm, "c:\\turboc3\\bgi " ); circle(200,100,150); getch(); closegraph(); } To run this program, you need graphics.h header file, graphics.lib library file and Graphics driver (BGI file) in the program folder. These files are part of Turbo C package. In all our programs we used 640x480 VGA monitor. So all the programs are according to that specification. You need to make necessary changes to your programs according to your screen resolution. For VGA monitor, graphics driver used is EGAVGA.BGI.

WHAT IS C++

C++ is an "object oriented" programming language created by Bjarne Stroustrup and released in 1985. It implements "data abstraction" using a concept called "classes", along with other features to allow object-oriented programming. Parts of the C++ program are easily reusable and extensible; existing code is easily modifiable without actually having to change the code. C++ adds a concept called "operator overloading" not seen in the earlier OOP languages and it makes the creation of libraries much cleaner. C++ maintains aspects of the C programming language, yet has features which simplify memory management. Additionally, some of the features of C++ allow low-level access to memory but also contain high level features.

WHAT IS C

The purpose of C is to precisely define a series of operations that a computer can perform to accomplish a task. Most of these operations involve manipulating numbers and text, but anything that the computer can physically do can be programmed in C. Computers have no intelligence- they have to be told exactly what to do and this is defined by the programming language you use. Once programmed they can repeat the steps as many times as you wish at very high speed. Modern PCs are so fast they can count to a billion in a second or two.
