C Program to create a House using Graphics

Last Updated : 14 Jun, 2020

Prerequisite: graphics.h, How to include graphics.h in CodeBlocks?

The task is to write C program to create a house using graphics.

To run the program we have the include the below header file:

  #include <graphic.h>

Setting Up the Environment:

Download the WinBGlm zip file from this link.
Extract the WinBGlm zip at any desired directory as shown below:
Copy the header file graphic.h and winbgim.h and paste these file inside the folder Program Files->CodeBlock->MinGW->Include_folder.
Also copy the libbgi.a and paste inside the folder Program Files->CodeBlock->MinGW-> lib_folder.
After this open your Code::Blocks and goto the Setting->Compiler->Linker Settings as shown below:
Add New and Browse the file where the libbgi.a is available which is lib folder.
And in other linker option paste this: “lbgi lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32“, Click on OK and Exit from Code::Blocks.

Approach: We will create a house with the help of several lines and rectangles. Below are the steps:

We will draw a line in graphics by passing 4 numbers to line() function as:

line(a, b, c, d)
The above function will draw a line from coordinates (a, b) to (c, d) in the output window.
IWe will draw a rectangle in graphics by passing 4 numbers to rectangle() function as:

line(left, top, right, bottom)
The above function will draw a rectangle with coordinates of left, right, top and bottom.
The setfillstyle() function which sets any fill pattern in any shape created in C program using graphics.
The floodfill() function is used to fill an enclosed area with any color.

Below is the implementation of the above approach:

   // C program to draw a house using 
// graphics.h library 
#include <conio.h> 
#include <graphics.h> 
#include <stdio.h> 
  
// Driver Code 
void main() 
{ 
    // Initialize of gdriver with 
    // DETECT macros 
    int gdriver = DETECT, gmode; 
  
    // Initialize structure of 
    // the house 
    initgraph(&gdriver, &gmode, ""); 
  
    // Create lines for structure 
    // of the House 
    line(100, 100, 150, 50); 
  
    line(150, 50, 200, 100); 
  
    line(150, 50, 350, 50); 
    line(350, 50, 400, 100); 
  
    // Draw rectangle to give proper 
    // shape to the house 
    rectangle(100, 100, 200, 200); 
    rectangle(200, 100, 400, 200); 
    rectangle(130, 130, 170, 200); 
    rectangle(250, 120, 350, 180); 
  
    // Set color using setfillstyle() 
    // which take style and color as 
    // an argument 
    setfillstyle(2, 3); 
  
    // Fill the shapes with colors white 
    floodfill(131, 131, WHITE); 
    floodfill(201, 101, WHITE); 
  
    // Change the filling color 
    setfillstyle(11, 7); 
  
    // Fill the shapes with changed colors 
    floodfill(101, 101, WHITE); 
    floodfill(150, 52, WHITE); 
    floodfill(163, 55, WHITE); 
    floodfill(251, 121, WHITE); 
  
    // Close the initialized gdriver 
    closegraph(); 
}
