Making anything...period

This is a discussion on Making anything...period within the Game Programming forums, part of the General Programming Boards category; I never use; using namespace std... I read I didn't "need" to. You're right; I'm sorry. However, it's good practice ...

    You're right; I'm sorry. However, it's good practice to always declare it, esepcially when making an example to a newbie.

    It's basically for when you need to have special instances.

    Here is a thread at allegro.cc that has some more information on using namespace. This will probably be better than having me try to explain it.
