How to setup... Download Code::Blocks from  here . You have to download the codeblocks-17.12mingw-setup.exe or codeblocks-17.12mingw nosetup.zip file. The first file(highlighted) is the install-able setup and the other one(highlighted) is portable zip file(not need to install). If you are beginners you prefer the first one. After the installation you locate the code blocks at location C:\Program Files (x86)\CodeBlocks or at C:\Program Files\CodeBlocks. You have to download the graphics file from this link  . Extras this zip file, it includes three files (two header files & a library file).   Now copy the graphics.h & winbgim.h header files and paste at location C:\Program Files (x86)\CodeBlocks\MinGW\include And copy the libbgi.a file at location C:\Program Files (x86)\CodeBlocks\MinGW\lib Now open the code blocks and follow the steps: 1.
