C++ Constructor error - Expected ')' before token '<'

Question

What is wrong wit the following constructor declaration? I keep getting this error:

Expected ')' before token '<'

class Environment{ public: Environment(vector<vector<char> > roomData); private: //.... };

Note: ok I see what's wrong. I did not add: using namespace std;

What's vector? If it is supposed to be std::vector, then did you include <vector>? And it is std::vector, not just vector, unless you have the corresponding using declaration or directive somewhere higher in the code.
