It(graphics.h) is called BGI(Borland Graphics Interface).It is an olden 32-bit real-mode DOS library, included with Borland's Turbo C and C++ products. And basically graphics.h, conio.h can be inferred as windows headerfiles. So It'll run only one windows.

The last Borland's C++ IDE for DOS is Borland C++ 3.1 (1992). The last C++ environment which supports BGI is Borland C++ 5.02 (1997), which works under Windows but can compile DOS programs. BGI was accessible in C/C++ with graphics.lib / graphics.h, and in Pascal via the graph unit.

BGI was less powerful than modern graphics libraries such as SDL or OpenGL, since it was designed for 2D presentation graphics instead of event-based 3D applications. However, it has been considered simpler to code. BGI and Turbo C++, although obsolete, are still widely used in education in India.

This repo is for practising C++ graphics (turbo c++) using graphics.h file.

1. Download Dev-cpp 5.11 TDM-GCC 4.9.2 from sourceForge.

2. Install Dev-cpp.

3. Download Graphics Files For Dev C++ from GDrive - without consoleAppGraphics template or studyReadEducate or GDrive for studyReadEducate and unzip.

4. Copy the following files to appropriate Dev-cpp folders

   • 🟢 This step is optional only: copy 6-ConsoleAppGraphics.template and ConsoleApp_cpp_graph.txt from Graphics in Dev C++ to C:\Program Files (x86)\Dev-Cpp\Templates\.
   • ✔️ Copy graphics.h and winbgim.h from Graphics in Dev C++ to C:\Program Files (x86)\Dev-Cpp\MinGW64\x86_64-w64-mingw32\include\.
   • ✔️ Copy libbgi.a from Graphics in Dev C++ to C:\Program Files (x86)\Dev-Cpp\MinGW64\x86_64-w64-mingw32\lib\.

5. Choose 32-bit GCC compiler:

   • ⚠️ Click on the dropdown in the main ribbon, & select TDM-GCC 4.9.2 32-bit release. as shown in below image

   

6. Choose compiler & add linkers as shown below:

   • ⚠️ Click on Tools and choose Compiler and Options

   • Other Linker Options required for the setup graphics.h

     -lbgi -lgdi32 -lcomdlg32 -luuid -loleaut32 -lole32

   

7. To create a new project:

   • File -> New -> Project
   • then select Console Graphics Application under basic tab
   • then choose your desired name & hit ok.
   • prompt will open file explorer, save the .dev file where you want to save your project.
   • --- OR ---
   • Click on File icon -> source file or ctr + N

8. To execute:

   • Click on execute in the main ribbon, then choose Compile & Run or press F11.

10. Test program

#include<graphics.h>

main(){
  initwindow(800, 800);
  //  creating line
  //  line(200, 210, 400, 410);

  //  creating circle (x, y, radius)
  circle(300, 300, 20);
  getch();
}

1. Download codeblocks-20.03mingw-setup (64 bit) from here.

   • 🟡v20.03 mingw 64-bit, 🟡v20.03 mingw 32-bit, 🟡v17.12 mingw, 🟡v16.01 mingw

2. Just install codeblocks setup.

3. As we've 64-bit version, we've to set up 32-bit GCC. Because our graphics library(graphics.h) is compatible with 32-bit.

4. Before moving on, to find the gcc version, Please do the below steps: -> This step is optional

   • 🟢 Cpp code to find the gcc version

     #include<stdlib.h>
   
     // c++ program to know the gcc version
     int main() {
       system("gcc -v");
       return 0;
     }

   • 🟢 The click on settings from the main ribbon, then choose Compiler...

   • 🟢 Then click on Linker settings in the tab from the dialog & remove all the linkers as shown below:

   • 🟢 Then click on Build from the main ribbon, then choose Build and Run or press F9 to compile & run.

   • 🟢 You can see the below output

5. Download 32-bit compiler from here and install it.

6. Download Graphics Files from here and unzip it.

7. Copy the following files form downloaded zip folder to the appropriate TDM-GCC-32 folders

   • ✔️ Copy graphics.h and winbgim.h from downloaded Graphics folder to C:\TDM-GCC-32\include\.
   • ✔️ Copy libbgi.a from downloaded Graphics folder to C:\TDM-GCC-32\lib.

8. Add the appropriate linkers

   • 🟢 The click on settings from the main ribbon, then choose Compiler...

   • 🟢 Then click on Toolchain executables in the tab from the dialog and choose the new 32-bit gcc compiler as shown below:

   • 🟢 Then click on Linker settings and add the following linker tags under Other linker options and then hit save as shown below:

9. Create a new project

   • Click on File -> New -> Project -> Console Application, then click on Go
   • Click on Next, then choose C++ and go on with the prompt.
   • After writing a program, click on compile and run

10. Test program

  #include <graphics.h>

  int main(){
    int gd=DETECT, gm;
    initgraph(&gd, &gm, (char*)"");
    circle(320, 240, 200);
    getch();
    closegraph();
    return 0;
  }

11. Changing indentation: settings -> Editor
