OUTPUT PRIMITIVES

EX.NO:5          OUTPUT PRIMITIVES

Aim:

     To write a C Program to display the output primitives.

Algorithm:

1.           Start the  program .

2.           Initialize the variables.

3.           Call the  initgraph() function

4.           Set color for the output primitives.

5.           Using Outtextxy() display the choosen particular primitives.

6.           Using switch case mention the various primitives and their attributes.

7.           The various primitives are arc, line ,circle, rectangle and ellipse.

8.           close the graph and run the program.

9.           stop the program.

PROGRAM:

#include<stdio.h>

#include<conio.h>

#include<graphics.h>

#include<string.h>

void main()

{

char ch='y';

int gd=DETECT,gm,x1,y1,x2,y2,rad,sa,ea,xrad,yrad,i;

initgraph(&gd,&gm,"");

while(ch=='y')

{

cleardevice();

setbkcolor(9);

outtextxy(100,150,"Enter 1 to get line");

outtextxy(100,170,"2.Circle");

outtextxy(100,190,"3.Box");

outtextxy(100,210,"4.Arc");

outtextxy(100,230,"5.Ellipse");

outtextxy(100,250,"6.Rectangle");

outtextxy(100,270,"7.Exit");

ch=getch();

cleardevice();

switch(ch)

{

case '1':

line(100,200,300,400);

case '2':
