2. > Dùng lệnh getch() trong thư viện conio.h (console input output) không phải chuẩn của C. Nên không nên dùng lệnh này để dừng chương trình.

   . Dùng lệnh system("pause"); để dừng chương trình là chuẩn rùi. . Khi viết code cần chú ý nhé. Code C thì lưu đuôi là *.c Còn code C++ thì lưu là *.cpp . Cái đuôi này nhiều người hay nhầm, viết code là C, nhưng toàn lưu là *.cpp (đuôi của C++). sai bản chất.

. You’re missing some basic C++ knowledge. Try googling for ‘scope’ and/or take out a C++ book and read a bit more. The problem is, that the window gets declared in the main() function and now you’re trying to acces that variable in the loadLevel(), this doesn’t work since the loadLevel() has no idea what has happend in the main() function and thus has also no access to any of it’s variables.
