Store pointer pointing to object contained in map

Question

Im wondering whether this snippet of code will actually store a pointer pointing to object which is managed by a map:

std::map<std::string,MapType> map;
MapType* typePointer;

typePointer = map[someKey];

Answer 1

typePointer = &map[someKey];

Answer 2

No, it won't.

You are storing the MapType , not MapType* inside the map. Consequently, the last line is a type mismatch and won't compile.
