C GRAPHICS PROGRAMS

C GRAPHICS PROGRAMS

Before starting any graphics program in C just keep a syntax in your mind which will be required in every graphics program of C.

                                      #include<graphics.h>

                                       void main()

                                                {

                                              int gd=DETECT,gm;

                                                 initgraph(&gd,&gm,”C:\\TURBOC3\\bgi”);

                                                

                                        }

So now move on to our programs………

 1.       C program to create a circle

#include<graphics>

#include<conio.h>

#include<stdio.h>

void main()

{

  clrscr();    // clears the screen

  int gd=DETECT,gm;

  initgraph(&gd,&gm,”C:\\TURBOC3\\bgi”);

  int x,y,radius;

  printf(“Enter the radius of circle”);

  scanf(“%d”,&radius);

 printf(“Enter the x position of circle);

 scanf(“%d”,&x);

 printf(“Enter the y position of circle);

scanf(“%d”,&y);

circle(x,y,radius);

getch();
closegraph();

}

   2.  C program to create a line

#include<graphics.h>

#include<conio.h>

#include<stdio.h>

void main()

 {

   clrscr();

   int gd=DETECT,gm;

  initgraph(&gd,&gm,”C:\\turboc3\\bgi”);

  int x1,y1,x2,y2;

  printf(“Enter the x1 coordinate of rectangle”);

  scanf(“%d”,&x1);

  printf(“Enter the y1 coordinate of rectangle”);

  scanf(“%d”,&y1);

  printf(“Enter the x2 coordinate of rectangle”);

 scanf(“%d”,&x2);

 printf(“Enter the y2 coordinate of rectangle”);

  scanf(“%d”,&y2);
  cleardevice();

 line(x1,y1,x2,y2);
getch();
closegraph();

}

3.       C program to create a rectangle

#include<graphics.h>

#include<conio.h>

#include<stdio.h>

void main()

 {

   clrscr();

   int gd=DETECT,gm;

  initgraph(&gd,&gm,”C:\\turboc3\\bgi”);

  int left,top,right,bottom;

  printf(“Enter the left coordinate of rectangle”);

  scanf(“%d”,&left);

  printf(“Enter the right coordinate of rectangle”);

  scanf(“%d”,&right);

  printf(“Enter the top coordinate of rectangle”);

 scanf(“%d”,&top);

 printf(“Enter the bottom coordinate of rectangle”);

  scanf(“%d”,&bottom);
  cleardevice();

 rectangle(left,top,right,bottom);
 getch();
 closegraph();

}
