void main(void) {  
    int gdriver = DETECT, gmode;
    int x1 = 200, y1 = 200;
    int x2 = 300, y2 = 300;

    initgraph(&gdriver, &gmode, "c:\\turboc3\\bgi");
    line(x1, y1, x2, y2);


Explanation of Code :  
1. int x1=200, y1=200;  
   int x2=300, y2=300;
   We have declared above variables so that we can keep track of starting and ending point.

2. line(x1,y1,x2,y2);  
   We need to pass just 4 parameters to the line() function.

3. Line Function Draws Line From (x1,y1) to (x2,y2) .  
    Syntax : line(x1,y1,x2,y2);
    ->Parameter    Explanation
        x1    X Co-ordinate of First Point
        y1    Y Co-ordinate of First Point
        x2    X Co-ordinate of Second Point
        y2    Y Co-ordinate of Second Point
