C++ How to dynamically create a 2D vector

Question

I\'m trying to create an n x n vector that I can later cout as a table/matrix. Xcode points to the = in the for loop and tells me No

Answer 1

When the constructor of row is called, all elements are initialized too. I think this code does what you're looking to do:

for (int i=0; i

Now all elements of row will be of size n.
