@zaasmi said in CS602 Assignment 1 Solution and Discussion:
Question 1) Write a program in Dev C++ to draw a circle. Also, use the flood fill algorithm to fill the circle with different lines of red color. The output of your program should like the below image:
Solution:
// C Implementation for setfillstyle
// and floodfill function
#include <graphics.h>
// driver code
int main()
{
// gm is Graphics mode which is
// a computer display mode that
// generates image using pixels.
// DETECT is a macro defined in
// "graphics.h" header file
int gd = DETECT, gm;
// initgraph initializes the
// graphics system by loading
// a graphics driver from disk
initgraph(&gd, &gm, " ");
// center and radius of circle
int x_circle = 250;
int y_circle = 250;
int radius=100;
// setting border color
int border_color = WHITE;
// set color and pattern
setfillstyle(HATCH_FILL,RED);
// x and y is a position and
// radius is for radius of circle
circle(x_circle,y_circle,radius);
// fill the color at location
// (x, y) with in border color
floodfill(x_circle,y_circle,border_color);
getch();
// closegraph function closes the
// graphics mode and deallocates
// all memory allocated by
// graphics system
closegraph();
return 0;
