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

Try the following

int n = 5;
std::vector< std::vector > row(n);
for (int i=0; i(n) );
}

or

int n = 5;
std::vector< std::vector > row(n, std::vector( n ) );
