Turbo C - Using line and setlinestyle function





I have given here the graphics source code in Turbo C for line and setlinestyle function. line function is used to draw a line and will take 4 arguments x1, y1, x2, and y2. setlinestyle will take 3 arguments of which the first argument is used to specify the line styles - SOLID_LINE, DOTTED_LINE, CENTER_LINE, DASHED_LINE, USERBIT_LINE. The rand and randomize functions are used for animation.


Source Code


#include <graphics.h>

#include <math.h>

#include <conio.h>

#include <dos.h>

#include <stdlib.h>

 

 

 

void main()

{

      int i, grd, grm;

      int x1, y1, x2, y2;

      detectgraph(&grd,&grm);

      initgraph(&grd, &grm, "");

 

 

      while(!kbhit())

      {

            randomize();

            setfillstyle(SOLID_FILL, BLUE);

            bar(1,1,638,478);

            setcolor(WHITE);

            rectangle(0,0,639,479);

 

            for(i = 0; i < 120; i++)

            {

                  setcolor(rand() % 15);

                  setlinestyle(rand() % 4, 1, 1);

                  x1 = rand() % 639;

                  y1 = rand() % 479;

                  x2 = rand() % 639;

                  y2 = rand() % 479;

                  line(x1, y1, x2, y2);

                  delay(1);

            }

 

      }

 

      getch();

      closegraph();

}
