How can I use an array as map value?

Question

I\'m trying to create a map, where the key is an int, and the value is an array as follows:

int red[3]   = {1,0,0};
int green[3] = {0,1,0};
int b

Arrays are not first class constructs in C++. They are not Copy Constructible nor Assignable which are requirements for values of std::map. You can use boost::array or std::vector.
