/*  C Program to Draw Line using Graphics  */

#include <graphics.h>
#include <stdio.h>
#include <conio.h>
#include <math.h>
void main() {
        int gd = DETECT, gm = DETECT, s, dx, dy, m, x1, y1, x2, y2;
        float xi, yi, x, y;
        clrscr();
        printf("Enter the sarting point x1 & y1\n");
        scanf("%d%d", &x1, &y1);
        printf("Enter the end point x2 & y2\n");
        scanf("%d%d", &x2, &y2);
        initgraph(&gd, &gm, "");
        cleardevice();
        dx = x2 - x1;
        dy = y2 - y1;
        if (abs(dx) > abs(dy))
                s = abs(dx); else
                s = abs(dy);
        xi = dx / (float) s;
        yi = dy / (float) s;
        x = x1;
        y = y1;
        putpixel(x1, y1, 4);
        for (m = 0; m < s; m++) {
                x += xi;
                y += yi;
                putpixel(x, y, 4);
        }
        getch();
