i m working on Graphics and Animation laboratory exercise of de2 board i wand to draw a line using

Bresenham’s algorithm

the c code is # include<stdio.h># include<conio.h># include<graphics.h>

void main()

int gd = DETECT, gm;

int dx, dy, p, end;

float x1, x2, y1, y2, x, y;

initgraph(&gd, &gm, "c:\tc\bgi");

printf("Enter Value of X1: ");

scanf("%f", &x1);

printf("Enter Value of Y1: ");

scanf("%f", &y1);

printf("Enter Value of X2: ");

scanf("%f", &x2);

printf("Enter Value of Y2: ");

scanf("%f", &y2);

dx = abs(x1 - x2);

dy = abs(y1 - y2);

p = 2 * dy - dx;

if(x1 > x2)

x = x2;

y = y2;

end = x1;

else

x = x1;

y = y1;

end = x2;

putpixel(x, y, 10);

while(x < end)

x = x + 1;

if(p < 0)

p = p + 2 * dy;

else

y = y + 1;

p = p + 2 * (dy - dx);

putpixel(x, y, 10);

getch();

closegraph();

what changes i need to do for compile on altera monitor program
