I'm learning c++

And my compiler is letting me do something weird.


If I do this:

int x; //matrix-size

cin >> x;

int array[x];

I can compile. I don't even get a warning. (I'm using the Codelite IDE for Linux, compiler is g++)

Does this work in c++ or is my compiler just fucking with me?

So I guess all these classes I'm tripping over are just in my imagination, then?
