|You're using TC++ 3.0 at home, but what did you use at school? If it's a different brand of compiler, or even a different version of TC++, you're likely to encounter differences in the libraries. That would explain why the graphics errors -- the two compilers have their own, incompatible, libraries (there is no widely accepted C/C++ graphics library standard). You'll just have to rewrite the code to use TC++'s graphics calls.|
As for the int int int int problem, that could be almost anything. Could 4 "int" declarations have lost their variables and semicolons? You're going to have to do some digging here to get to the bottom of this.
