運作原理

語法

   template<typename TypeVar>   class Stack{ };

     template<typename TypeVar> void func(){}

// template <typename TypeVar>;// 從以往的值變成型態作為值// typename 為型別名稱// 上述的 Type 為通用型態的指示元，是變數容器的名稱// 加入關鍵字    template <typename TypeVar>class Stack{    private:enum {MAX=10}; // constant: ClassTypeVar items[MAX] = {9, 8, 7, 6, 5, 4, 3, 2, 1, 0}; // item holderint top; // index    public:Stack();bool isFull() const;bool isEmpty() const;bool pop(int& item);};// 加入關鍵字template <typename TypeVar>bool Stack::pop(const TypeVar& item){    //...};

inline 或稱 unfold, 內聯

 To replace a function call withan instance of the function's body.    Actual argumentexpressions are substituted for formal parameters as in beta reduction.  Inlining is usually done as a compile-time transformation.
