Jan 16, 2018 graphics.h library is used to include and facilitate graphical operations in program. Graphics.h functions can be used to draw different shapes, display text in different fonts, change colors and many more. Using functions of graphics.h you can make graphics programs, animations, projects and games. You can draw circles, lines, rectangles, bars and many other geometrical figures.

C++ programming language is a versatile programming language. Using C++ you can create low end graphics too i.e. creating basic shapes and words with stylish fonts and adding colors to them can be done using c++.
Graphic programming can be done in c++ using your terminal or command prompt or you can download DevC++ compiler to create graphic programs.
For terminal you need to add the graphics.h libraray to you GCC compiler. For this you will have type in the following commands.
On sequentially typing all the above commands you can successfully install the graphics.h library in your GCC compiler of terminal.
for or the other method you need to install the DevC++ compiler.
graphics.h library − The graphic.h library is used to add graphics to your C++ program. For graphic programming, it is a must include library as it contains all required methods.

Program to show implementation of graphic programming in c++ −
Output
Other Common functions of of C++ graphic programming are −
- arc() − creates arc of a given angle and given radius.
- bar() − creates a bar with given coordinates.
- circle() − creates a circle of given radius.
- closegraph() − it closed the graphics mode and deallocated memory chunks.
- ellipse() − creates an ellipse with given major and minor axis.
- floodfill() − flood fill is used to fill a specific color to a specific point whose coordinates are given.
- line() − creates a line of given starting and ending points.
- rectangle() − creates a rectangle with given coordinates.
Graphics programming in C used to drawing various geometrical shapes(rectangle, circle eclipse etc), use of mathematical function in drawing curves, coloring an object with different colors and patterns and simple animation programs like jumping ball and moving cars.

2. Explanation of Code :
The first step in any graphics program is to include
graphics.h
header file. The graphics.h
header file provides access to a simple graphics library that makes it possible to draw lines, rectangles, ovals, arcs, polygons, images, and strings on a graphical window.The second step is initialize the graphics drivers on the computer using
initgraph
method of graphics.h
library.It initializes the graphics system by loading the passed graphics driver then changing the system into graphics mode. It also resets or initializes all graphics settings like color, palette, current position etc, to their default values. Below is the description of input parameters of initgraph function.
Graphics In Dev C++ Download
- graphicsDriver : It is a pointer to an integer specifying the graphics driver to be used. It tells the compiler that what graphics driver to use or to automatically detect the drive. In all our programs we will use
DETECT
macro of graphics.h library that instruct compiler for auto detection of graphics driver. - graphicsMode : It is a pointer to an integer that specifies the graphics mode to be used. If
*gdriver
is set toDETECT
, theninitgraph
sets*gmode
to the highest resolution available for the detected driver. - driverDirectoryPath : It specifies the directory path where graphics driver files (
BGI files
) are located. If directory path is not provided, then it will search for driver files in current working directory directory. In all our sample graphics programs, you have to change path of BGI directory accordingly where you Turbo C++ compiler is installed.
We have declared variables so that we can keep track of starting and ending point.
No, We need to pass just 4 parameters to the
line

Function Draws Line From (x1,y1) to (x2,y2) .Graphics Programming In C Language
Parameter Explanation
- x1 - X Co-ordinate of First Point
- y1 - Y Co-ordinate of First Point
- x2 - X Co-ordinate of Second Point
- y2 - Y Co-ordinate of Second Point
At the end of our graphics program, we have to unloads the graphics drivers and sets the screen back to text mode by calling
closegraph
function.Graphics Programming In C In Dev C++
3. Colors in C Graphics Programming
There are 16 colors declared in graphics.h header file. We use colors to set the current drawing color, change the color of background, change the color of text, to color a closed shape etc (Foreground and Background Color). To specify a color, we can either use color constants like setcolor(RED), or their corresponding integer codes like setcolor(4). Below is the color code in increasing order.
