C++ vector ERROR: subscript out of range - c++

Question

I'm a C++ noob, currently trying to create a text based maze game for degree. I'm replacing my currently working array with a vector (for dynamic size) and reading a txt file of chars to it.
PROBLEM: I get no IDE errors, but get RUNTIME ERROR: Debug assertion Failed! Expression: vector subscript out of range!
I have used the pushback instead of RoomFile=data, but I don't know if I need to amend other functions. I read the array/vector data in another class (player) and will include code if needed.
I have searched everywhere to find solution, but can't find any projects using a similar vector structure. What am I doing wrong?

Answer 1

I think this is the error: What you are printing in PrintRoom is the std::vector<char> data inside your class, while the std::vector<char> data that you filled up is local to CreateRoom method.
void Room::CreateRoom(int RoomNo)
{
std::vector<char> data; // remove this to solve

Answer 2

In your PrintRoom() function, you have
cout << data[col * height + row];
instead of
cout << data[row * height + col];
