~Instructions~

First download code blocks software.

First open code block official site which is www.codeblocks.org

Then click on download option

Click on “download the binary release”

Download the code-blocks-mingw-setup.exe

Wait until it download

Now install it

Double click on code blocks setup

Click on next next unless it start installing, don’t change installation path.

It will take some time for installation

how to download install code blocks

how to download and install code blocks

After installation, we need some header files to run graphics

program. Follow the given link to download these files http://winbgim.codecutter.org/

Click on the first link and download the file

Now extract the downloaded file

# how to install code blocks

How to open the graphic.h file in notepad and go to line number 302 and replace the word right with top and save it as I show you

Now copy the graphics.h and wibgim.h file and paste in header file directory

# how to install code blocks and how to run graphics program in code blocks

Now copy the libbgi.a file and paste in code block’s lib folder

Now open code blocks and go to settings then compiler then linker setting

Click on add button and browse libbgi.a file which is we copied in lib folder

After that copy the command from the description and paste them in right section which is other linker option. Then click ok .

Now we are done

Now try to run graphics program to check whether it is working or not

Program is build and run successfully

Basic Graphic Programming in C++

Introduction
So far we have been using C language for simple console output only. Most of us are unaware that using C++, low level graphics program can also be made. This means we can incorporate shapes,colors and designer fonts in our program. This article deals with the steps to enable the DevC++ compiler to generate graphics .
Configuring DevC++

Step 1: Download the DevC++ version 5.11 from here.
Step 2: Download the Graphics header files, and etc stuff needed from the given dropbox link.
Step 3: Extract the contents of the rar file.
Step 4: Go to the location where DevC++ is installed. For me its D drive. Go inside the MinGW64 folder. Copy the graphics.h and winbgim.h in the include folder and D:\Dev-Cpp\MinGW64\x86_64-w64-mingw32\include folder.
Step 5:Copy the libbgi.a file into lib folder and in D:\Dev-Cpp\MinGW64\x86_64-w64-mingw32\lib folder.
Step 6: Copy the ConsoleAppGraphics.template, ConsoleApp_cpp_graph.txt files and paste them inside the template folder of the devc++ installer location.

Now we are done with configuring of the DevC++ to support graphics programming. We shall write our very first graphics program now.
Running the first graphics program

Open DevC++. Click file ->New ->Project.
Make sure you get the Console Graphics option. However, we are not going to click on it.
Choose Empty Project option and Give a project name and make sure the selected language is C++.

Copy the following code to the editor window.

#include<graphics.h>
#include <conio.h>
int main()
{
    int gd = DETECT, gm;
    initgraph(&gd,&gm, "C:\\tc\\bgi");
    circle(300,300,50);
    closegraph();
    getch();
}

Go to “Project” menu and choose “Project Options” (or just press ALT+P).
Go to the “Parameters” tab In the “Linker” field, enter the following text:
-lbgi
-lgdi32
-lcomdlg32
-luuid
-loleaut32
-lole32
Click OK and Compile and run the project and you’ll get this output:

Program Explanation

The initgraph function- ?Initializes the graphics system.
In C Program execution starts with main() similarly Graphics Environment Starts with this function.
initgraph() initializes the graphics system by loading a graphics driver from disk (or validating a registered driver) then putting the system into graphics mode
