Message: [QUOTE="Kei, post: 3790669"] Hello, I am trying to add a simple search behaviour to a STL Vector like the following: //---- declaration --- typedef struct { std::string name; std::string favouriteFood; } TBuddy; typedef TBuddy* PBuddy; class TBuddies: public std::vector<PBuddy> { public: std::string favouriteFoodOf(const std::string& name) const; }; //---- implementation --- std::string TBuddies::findValue(const std::string& name) const { for(TBuddies::iterator i= this->begin(); i!= this->end(); ++i) { PBuddy b = *i; if(b->name ==s) return b->favouriteFood; } return ""; } But it couldn't compile... There is a strange error saying "Invalid conversion from TBuddy const* const to TBuddy**". But the "const" keyword in the function is required. Somehow, is the iterator trying to modify the instance ? Thanks! [/QUOTE]
