Compile Problem - Dev C++

Hi everyone!

I've downloaded some sample programs to study the code, but when I try to compile these programs, its gives me a lot of compile errors. Im using Dev C++ 4.9.9.2

For what i've searched the problem is not really in the code, but in the IDE I'm using, but i couldnt find anything more deep about. If someone knows why this is happening I'll be very gratefull. Thank you

One of the codes i've tryed, for a snake game program.

Code:

Well posting some ACTUAL warning / error messages would be a start...

Sorry, I didn't post it at first because I though the problem was not in the code, but on the program I was using to compile it. Already updated it with the code and the error log

Well the problem is this.

You're trying to compile an ancient DOS program written for something like Turbo-C, using a compiler which is primarily targeted at producing Win32 executables.

I see, I suspected it was something like that, thanks a lot!!
