Simple 2D Racing Game with C/C++

Simple 2D Racing Game with C\C++ : The following , is a simple 2D racing game , created , using the BGI graphics library of Turbo C/C++ 3.0 :


While running this program , make sure that, you used the correct path for the BGI graphics driver .For example : if Turbo C/C++ is installed in the following location "C:\TC" , then the BGI graphics path should be "C:\\TC\\BGI" :

Simple 2D Pinball Game using C/C++

Simple 2D Pinball Game with C\C++ :  Following , is a simple 2D Pinball game(like DX-Ball,Para etc.) , created , using the BGI graphics library of Turbo C/C++ 3.0.

While running this program , make sure using correct path for the BGI graphics driver .For example : if Turbo C/C++ is installed in the following location "C:\TC" , then the BGI graphics path should be "C:\\TC\\BGI" :
