Difficulty: 8
How flexible can you make this simple container class? Hint: You'll learn more than a little about member templates along the way.

template<typename T, size_t size> class fixed_vector { public: typedef T* iterator; typedef const T* const_iterator; iterator begin() { return v_; } iterator end() { return v_+size; } const_iterator begin() const { return v_; } const_iterator end() const { return v_+size; } private: T v_[size]; }; ...Get Exceptional C++: 47 Engineering Puzzles, Programming Problems, and Solutions now with the O’Reilly learning platform.
