C program to draw the Olympics Logo using graphics

In this article, we will discuss how to design the Olympics Logo using Graphics.

Approach:

• Draw five circles according to positions in the logo using the function circle().
• To achieve the outline effect, draw 5 smaller circles over it.
• There is a black circle as well in the logo and to prevent it from blending in, change the background color.
• Color all the circles and the background to their respective colors using functions setfillstyle() and floodfill().

Below is the implementation of the above approach:

C

// C program for the above approach

#include <conio.h>
#include <graphics.h>
#include <stdio.h>

// Driver Code
void main()
{
    int gd = DETECT, gm;

    // Initialize of gdriver
    initgraph(&gd, &gm, "C:\\turboc3\\bgi");

    // Create Background color as Grey
    setfillstyle(SOLID_FILL, DARKGRAY);
    floodfill(50, 50, 15);

    // Create two circles in each
    // another & color Blue
    setfillstyle(SOLID_FILL, BLUE);
    circle(300, 300, 100);
    circle(300, 300, 90);
    floodfill(202, 300, 15);

    // Create two circles in each
    // another & color Yellow
    setfillstyle(SOLID_FILL, YELLOW);
    circle(400, 400, 100);
    circle(400, 400, 90);
    floodfill(322, 350, 15);
    floodfill(302, 400, 15);

    // Create two circles in each
    // another & color Black
    setfillstyle(SOLID_FILL, BLACK);
    circle(520, 300, 100);
    circle(520, 300, 90);
    floodfill(442, 350, 15);
    floodfill(422, 300, 15);

    // Create two circles in each
    // another & color Green
    setfillstyle(SOLID_FILL, GREEN);
    circle(620, 400, 100);
    circle(620, 400, 90);
    floodfill(522, 400, 15);
    floodfill(542, 350, 15);

    // Create two circles in each
    // another & color Red
    setfillstyle(SOLID_FILL, RED);
    circle(740, 300, 100);
    circle(740, 300, 90);
    floodfill(642, 300, 15);
    floodfill(662, 350, 15);

    // Hold the screen for a while
    getch();

    // Close the initialized gdriver
    closegraph();
}

Output:
