Jun 13, 2012 The C programming language defines a number of header files. Everyone has those header files. Graphics.h is something that YOU have, because YOU have turbo C and it comes with turbo C. Almost nobody else has it, because nobody else uses turbo C. The best advice I can give you is to not use turbo c. It's really, really old. Multiple examples are available for users to use graphics in C language and create design and make anything using graphics. Mainly 'graphics. H' header file is use for graphics functions.
How to use graphics.h in latest IDE's & Editors 2018
Just Follow the Steps for CODE::BLOCKS :-
- Clone the files from this repository. And download the Code::Blocks.
- Now copy the graphics.h & winbgim.h header files in
C:Program FilesCodeBlocksMinGWinclude
directory. - Now copy the libbgi.a library file in
C:Program FilesCodeBlocksMinGWlib
directory.
Note:
It may possible that your codeblocks installation is in another folder like Program Files(x86) by default codeblocks is installed in this directory. So find your path accordingly.- Now open your codeblocks and go to
Settings > Compiler Settings > Linker Settings
. Click onAdd
to link libraries and browse your libbgi.a library file; should be likeC:Program FilesCodeBlocksMinGWliblibbgi.a
. - In Linker Settings paste these linkers in Other linker options.
- Cheers
? ? Now run any graphics program. Remember that your program should be like name_of_file.cpp
. BecauseC
doesn't support sstream.
For Dev C++ you have to do the same upto Linker step. You need to add linkers with the project, just paste the linkers in
Project Options > Parameters > Linkers
. Or You can do it every project by pasting it in Tools > Compiler Options > General > in second textbox
Just Follow the Steps for Atom :-
- Clone the files from this repository. And download the Atom.
- Download the GCC compiler MinGW. And install it. Mark all options for installation.
- Set the path for the compiler. Go to
Control Panel > System > Advanced System Settings > Environment Variables > Path > Edit > New > paste C:MinGWbin
- Now open the Atom and install a package
gpp-compiler
from press (ctrl + comma) it'll open settings > Install. - After that paste those linkers, go to
Open settings > Packages > Settings of gpp-compiler package > C++ Compiler Options
. - Done! Create new file and press f5 to run the program.
- First Download the suitable binary file, according to your Linux OSThe current release of SDL_bgi is 2.2.3. To compile it from sources, you will need a compiler (gcc or clang are fine), make, and SDL2. On Debian and Ubuntu-like distributions, you will need the package 'libsdl2-dev' and its dependencies.
Building has been tested on GNU/Linux Mint 18.*, Fedora 26, Windows (MSYS2 + mingw-w64, Code::Blocks, Dev-C++ ), and Mac OS X Yosemite.
- Sources: SDL_bgi-2.2.3.tar.gz
- Source RPM package: SDL_bgi-2.2.3-1.src.rpm
- 64 bit binary RPM package (Fedora): SDL_bgi-2.2.3-1.x86_64.rpm
- 64 bit binary DEB package, for Debian-like Linux distributions: sdl_bgi_2.2.3-1_amd64.deb
- binaries for Windows (MSYS2 + mingw-w64, CodeBlocks, Dev-C++):
SDL_bgi-2.2.3-win.zip - Previous versions sources:
SDL_bgi-2.2.2.tar.gz
SDL_bgi-1.0.1.tar.gz
- To compile a program using SDL_bgi, make sure that it includes the 'graphics.h' header file. Then:
gcc -o program program.c -lSDL_bgi -lSDL2
- If you want to integrate this with your favourite editors the simply add linker.
-lSDL_bgi
-lSDL2
-->
The names of program elements such as variables, functions, classes, and so on must be declared before they can be used. For example, you can't just write
x = 42
without first declaring 'x'.The declaration tells the compiler whether the element is an int, a double, a function, a class or some other thing. Furthermore, each name must be declared (directly or indirectly) in every .cpp file in which it is used. When you compile a program, each .cpp file is compiled independently into a compilation unit. The compiler has no knowledge of what names are declared in other compilation units. That means that if you define a class or function or global variable, you must provide a declaration of that thing in each additional .cpp file that uses it. Each declaration of that thing must be exactly identical in all files. A slight inconsistency will cause errors, or unintended behavior, when the linker attempts to merge all the compilation units into a single program.
To minimize the potential for errors, C++ has adopted the convention of using header files to contain declarations. You make the declarations in a header file, then use the #include directive in every .cpp file or other header file that requires that declaration. The #include directive inserts a copy of the header file directly into the .cpp file prior to compilation.
C Header Files Example
Note
In Visual Studio 2019, the C++20 modules feature is introduced as an improvement and eventual replacement for header files. For more information, see Overview of modules in C++.

Example
The following example shows a common way to declare a class and then use it in a different source file. We'll start with the header file,
my_class.h
. It contains a class definition, but note that the definition is incomplete; the member function do_something
is not defined:Next, create an implementation file (typically with a .cpp or similar extension). We'll call the file my_class.cpp and provide a definition for the member declaration. We add an
#include
directive for 'my_class.h' file in order to have the my_class declaration inserted at this point in the .cpp file, and we include <iostream>
to pull in the declaration for std::cout
. Note that quotes are used for header files in the same directory as the source file, and angle brackets are used for standard library headers. Also, many standard library headers do not have .h or any other file extension.Dev C++ Graphics Code
In the implementation file, we can optionally use a using statement to avoid having to qualify every mention of 'my_class' or 'cout' with 'N::' or 'std::'. Don't put using statements in your header files!
Now we can use
my_class
in another .cpp file. We #include the header file so that the compiler pulls in the declaration. All the compiler needs to know is that my_class is a class that has a public member function called do_something()
.After the compiler finishes compiling each .cpp file into .obj files, it passes the .obj files to the linker. When the linker merges the object files it finds exactly one definition for my_class; it is in the .obj file produced for my_class.cpp, and the build succeeds.

Include guards
C++ Graphics Header File
Typically, header files have an include guard or a
#pragma once
directive to ensure that they are not inserted multiple times into a single .cpp file.What to put in a header file
Because a header file might potentially be included by multiple files, it cannot contain definitions that might produce multiple definitions of the same name. The following are not allowed, or are considered very bad practice:
Graphics.h Header File For Dev C++
- built-in type definitions at namespace or global scope
- non-inline function definitions
- non-const variable definitions
- aggregate definitions
- unnamed namespaces
- using directives
Use of the using directive will not necessarily cause an error, but can potentially cause a problem because it brings the namespace into scope in every .cpp file that directly or indirectly includes that header.
