Re: [Boost-users] Using unordered_set or unordered_map to hold small array(s) of ints

Can someone please provide an example of how to best use unordered_map/set to store/lookup many small arrays of integers.  e.g. unsigned int I[5] = {1000,3344455,12455222,8832232}; I'm guessing that there is no facility for using raw C++ arrays, and that one must wrap them in a struct.

I guess you mean C arrays and not C++ arrays as C++ arrays are probably std::vector's. C arrays or C++ vectors would work fine though, but you would need to supply your own comparison function, and if C arrays add an ending tag like zero or have a static length.
