Vector of fixed array in c++98

原文 2011-08-13 20:20:32 4 2 c++/ c++98

I need to store an indeterminable number of triangles in a vector, therefore, it would be something like:

std::vector<Point[3]>

But that is not valid C++98. What are other solutions that do not involve a triangle struct?

Thanks

Try a boost::array<Point, 3> . That should do the necessities.

You may define a struct
You may use pair<pair<Point,Point>,Point> type
If you can use latest C++, there are many options and one of them is using std::tuple . If there are more of such cases, you may implement your own tuple class taking 3 or more types.
