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?

I guess I could maybe put in a few lines with sizeof at the end of the program to output whether the array is actually x places long, or if it just assigned some random value to x on compile.
