Computer Graphics - C++ Programming Examples and Tutorials. You will find lots of easy to understand tutorials, articles, code, example for Computer Graphics in C++ Programming. Search Projects & Source Codes:: Lakshmi Narayana.A This code implements the classic game: Snake & Ladder. It can be played by two players. Animated 3D Car in Turbo C++ 3.0 - It consist of Lights effect, Sound Effect. Table of Content. Drawing Circle in Graphics Mode; C Program to check if mouse support is available or not. C Program to display mouse pointer in textmode. We shall write our very first graphics program now. Running the first graphics program. Click file ->New ->Project. Make sure you get the Console Graphics option. However, we are not going to click on it. Choose Empty Project option and Give a project name and make sure the selected language is. Analog Clock - This is a graphics program which depict a wall clock. Animated 3D Car in Turbo C++ 3.0 A simple rotation of an ellipse by different angle values.

In Turbo C graphics we use graphics.h functions to draw different shapes(like circle, rectangle etc), display text(any message) in different format(different fonts and colors). By using graphics.h we can make programs, animations and also games. These can be useful for beginners.

Functions Used :

  • delay(n): A function from dos.h header file is responsible for holding of the program for a while depending upon given value n.
  • setcolor(n): A function from graphics.h header file which set the color of pointer(cursor).
  • arc(x,y,a1,a2,r): A function from graphics.h header file which draw an arc with (x,y) as centre (a2-a1) as angle and r as radius.

Implementation:

// A C program to make a rainbow. This program would only
// work in Turbo C compiler in DOS compatible machine
#include<graphics.h>
voidrainbow()
// auto detection
intx, y, i;
// initialize graphics mode(passed three arguments to
// &gdriver is the address of gdriver variable, &gmode is
// 'C:Turboc3BGI' is the directory path where BGI files are stored
x = getmaxx() / 2;//finding centre x-ordinate of screen
y = getmaxy() / 2;//finding centre y-ordinate of screen
for(i=30; i<200; i++)
// delay function under dos.h for holding the
delay(100);
// selecting color for making of rainbow
// making of arc with fixed centre and increasing radius
}
// driver program
{
return0;
