2D vector with parametrized constructor

Question

I'm trying to create two dimensional std::vector, that will hold objects of this class I inherited. The problem I have is that this class has only one constructor, and that uses one parameter (std::string to be precise). #define HEIGHT 4 #define WIDTH 4 #include using std::vector; static vector > reaper(HEIGHT, vector (WIDTH)); This should create 4x4 matrix of Reaper objects in my vector. At least I know it would work if I had constructor with no parameters available. But, this is how I would instantiate Reaper object: Reaper r0("R0"); Reaper* r1 = new Reaper("R1"); Now, I can't figure out how to include this constructor into my vector construction?

Answer 1

You can use the vector(size_t n, const T& t) constructor to initialize the inner vector of reapers to some initial constant value, like static vector > reaper(HEIGHT, vector (WIDTH, Reaper("value"))); You seem to use this once for the outer vector --- you can use it for the inner vector as well. Alternately, you can create a 2d-vector of pointers to reapers.
