A proper way to create a matrix in c++

Question

I want to create an adjacency matrix for a graph. Since I read it is not safe to use arrays of the form matrix[x][y] because they don\'t check for range, I deci

Answer 1

What I would do is create my own class for dealing with matrices (probably as an array[x*y] because I'm more used to C (and I'd have my own bounds checking), but you could use vectors or any other sub-structure in that class).

Get your stuff functional first then worry about how fast it runs. If you design the class properly, you can pull out your array[x*y] implementation and replace it with vectors or bitmasks or whatever you want without changing the rest of the code.

I'm not totally sure, but I thing that's what classes were meant for, the ability to abstract the implementation well out of sight and provide only the interface :-)
