how do I pass a multidimensional vector to a function?

Question

There is a two-dimensional vector of the form

vector <vector<int>> vi (n, vector<int>(m, 0));

How can I pass it to a function, for example, by reference?

0

Well, if you have a function declared as

void func(vector<vector<int>>&v);

Or

void func(const vector<vector<int>>&v);

Then we pass

vector <vector<int>> vi (n, vector<int>(m, 0));

Just like

func(vi);

Or do you want to ask something else?
