C++ dynamic array

I would like to make a dynamic array of a class with a constructor that has paramaters.

Where does the constructor's size parameter go?

ex. twoDArrayInDisguise = new dynamicArray(size)*[size];

Does not work

You cannot do this directly (when using new[], the default constructor is used).

Instead, use a std::vector. You can initialise each element in terms of a reference object, e.g.:

std::vector<T> vec(size, T(/* args */));

In C++, you cannot dynamically create an array of a class with a constructor that has paramaters!
