You can get multidimensional arrays using STL vector like this: typedef vector<int> Vint; typedef vector<Vint> VVint; typedef vector<VVint> VVVint; with these in an include file, you can use Vint v; instead of the definition above, and VVint v; if you want v to be a 2d array. Strong type checking warns you of any inattention to detail in your usage. I use STL vectors of int, of short, and of double extensively in my simulation work. I like being able to use i<v.size() as the termination condition in a for statement. (It works once the vector has been properly initialized through allocating statements such as v.push_back(i), as is suggested, above. If you look into STL and find it attractive, I heartily recommend The C++ Standard Library, A Tutorial and Reference, by N. M. Josuttis. It gives both good overview and detailed syntax and more. -- Paul E Condon [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
