There is no source code for the c++ test app, since that's not what is to translate, the goal is, to translate the DLL library source code in directory "RCV pascal test.rar\RCV pascal test\original C rcv project\rcv project\source\tdcvehicle\", the game1.cpp is just there to show how the demo program initializes the variables which are used in the gamelab3.exe which works with the dll which should be translated (except that pascal translation isn't a DLL but a normal pascal unit).
