I have very simple and stupid trouble: std::map<b2Vec2, b2Body*> mTakePoints; mTakePoints.insert(std::make_pair(point, body));
I\'m facing something very amazing. (Scenario: Win7 pro 64 bit, VC2008 compiling 32 bit code) Say a main program instantiate a Class that uses a std::map.
Every time you insert a pair in a std::map whose key is a std::string, it makes two copies. You can avoid using raw pointers but it is exception-unsafe. Is there some way to use a smart pointer instea
In some classes I have an static std::m开发者_开发技巧ap with pointers inside. My question is if I need to delete at the end of the program or this memory is automatically freed. My concern is if the

How do you access an s开发者_如何学运维td::vector of the keys or values of an std::map? Thanks.
I am wondering if it is possible to create something like a predicate for a std::map for all of its values so I don\'t have to edit the values before I insert them into the map.
