Question

Been awhile since I’ve programmed in C++ however I have a slight problem that I’m trying to figure out.

Is it possible to make a 2 by 2 dynamic array where 1 dimension is not dynamic?

For example

array[2][Dynamic]?

It seems like a waste to make array[dynamic][dynamic] and when I only need to use the first [0][dynamic] and second [1][dynamic] values.

Should I use another data structure?

Thanks.

Arrays and pointers are basically equivalent, so you can achieve this with an array of pointers:

int* array[2];
array[0] = new int[x];
array[1] = new int[y];

You can still access it as you would multidimensional array:

array[0][x-1] = z;
