BY USING PRINTF AND SCANF

Using a rectangle(int,int,int,int)function of c graphics.

using include<graphic.h>

using ASCII codes and then using goto statements

using rectangle(int,int,int,int)
               <left,top,right,bottom>
it is a function in graphics.h

USING rectangle(int,int,int,int)
it is a function in graphics.h

including graphics.h
then initialising graphics system using initgraph
and using the function rectangle(int left,int top,int 
right,int bottom)

no answer

using rectangle(int right,int top,int left,int bottom) in 
graphics.h

first include the graphics.h file 
thus you can use the rectangle funtion give the proper 
parameters and the wor is done

Divide by Zero.

BY using #include<graphics.h>
we can draw rectangle.
The syntax is rectangle(int ,int ,int ,int)
{left,top,right,bottom}

printf("____________________");
printf("\n|\t\t|\n|\t\t|\n|\t\t|\n|\t\t|");
printf("____________________");

    by this way i think can be possible,though some 
adjustment may required...as per size of VDU.As per my 
opinion intervier asked for this answer....as C graphics is 
not so popularly used.
     Pardon me if i'm wrong & can also mail to me.
