Aim:- C program which draws a pie chart showing percentage of various components drawn with different filling styles and colors.

C programming code

/* Program to draw a pie chart */

#include<graphics.h>
#include<conio.h>
 
int main()
{
   int gd = DETECT, gm, midx, midy;
 
   initgraph(&gd, &gm, "C:\\TC\\BGI");
 
   setcolor(MAGENTA);

C graphics examples

1. Drawing concentric circles

#include <graphics.h>
 
int main()
{ 
   int gd = DETECT, gm;
   int x = 320, y = 240, radius;
 
   initgraph(&gd, &gm, "C:\\TC\\BGI");
 
   for ( radius = 25; radius <= 125 ; radius = radius + 20)
      circle(x, y, radius);
 
   getch();
   closegraph();
   return 0;
}

2. C graphics program moving car

#include <graphics.h>
#include <dos.h>
 
int main()
{
   int i, j = 0, gd = DETECT, gm;
 
   initgraph(&gd,&gm,"C:\\TC\\BGI");
 
   settextstyle(DEFAULT_FONT,HORIZ_DIR,2);
   outtextxy(25,240,"Press any key to view the moving car");
 
   getch();
 
   for( i = 0 ; i <= 420 ; i = i + 10, j++ )
   {
      rectangle(50+i,275,150+i,400);
      rectangle(150+i,350,200+i,400);
      circle(75+i,410,10);
      circle(175+i,410,10);
      setcolor(j);
      delay(100);
 
      if( i == 420 )
         break;
      if ( j == 15 )
         j = 2;
 
      cleardevice(); // clear screen
   }
 
   getch();
   closegraph();
   return 0;
}

Animation Graphics in Windows 7

Most of the functions are two dimensional except bar3d which draws a 3d bar, you can also implement these functions using already existing algorithms. You can also use these functions in C++ programs. You can use these functions for developing programs in Windows 7 and Vista using Dev C++ compiler. For that you need to download an additional package WinBGIm, download WinBGIm. Now open Dev C++ compiler go to tools->Package Manager, use install button and then browse the package location. Now create new project and select WinBGIm. This library also offers many functions which can be used for image manipulation, you can open image files, create bitmaps and print images, RGB colors and mouse handling.

g.drawLine(100,140,230,10);
g.drawOval(20,20,200,120);
g.setColor(Color.green);
g.fillOval(70,30,100,100);
}
}   

2. Html code:

<html>

<body>

<applet code="Lines.class"height=500 width=500>
</applet>

</body>

</html>

Run process:-

1- develop the applet code(.java)

2-compile the applet code(.class)

3-write the basic HTML structure format

4-develop the APPLET tag for the applet 

5-insert the APPLET tag in HTML code 

6-run it using appletviewer (appletviewer ______.html) or 

                       double clicking on (.htmlfile) you created.

This app is like a dictionary which consists of the core of all the B.Tech IT and CSE subjects which can be used for exams, labs and during interviews.
All those who want to be a part of the software development please contact me at sreedher.123@gmail.com
we need 15 students from any college belonging to CSE, IT or ECE branch.

Once you are done with the project you can even add it to your resume which will be and added advantage.
You will also be paid after the project getting success.

I hope that it is a good opportunity to all those who want do some thing new and once the project is done it will be used by everyone around us.
