堆栈实现（C++）

用顺序结构（数组）与模板技术实现Stack如下：
View Code

const int MAXSTACK = 10;

template<class T>
class ZtkStack{
public:
    ZtkStack();
    bool empty() const;
    ErrorCode pop();
    ErrorCode top(T &item) const;
    ErrorCode push(const T &item);
private:
    int count;
    T entry[MAXSTACK];
};

template<class T>
ZtkStack<T>::ZtkStack():count(0)
{
}

template<class T>
bool ZtkStack<T>::empty() const
{
    bool outcome = true;
    if(count > 0)
        outcome = false;
    return outcome;
}

template<class T>
ErrorCode ZtkStack<T>::pop()
{
    ErrorCode outcome = success;
    if(count>0)
        --count;
    else
        outcome = underflow;
    return outcome;
}

template<class T>
ErrorCode ZtkStack<T>::push(const T &item)
{
    ErrorCode outcome = success;
    if(count < MAXSTACK)
        entry[count++] = item;
    else
        outcome = overflow;
    return outcome;
}

template<class T>
ErrorCode ZtkStack<T>::top(T &item) const
{
    ErrorCode outcome = success;
    if(count > 0)
        item = entry[count - 1];
    else
        outcome = underflow;
    return outcome;
}

资料：C++编译器不能支持对模板的分离式编译， http://blog.csdn.net/pongba/article/details/19130原文链接: https://www.cnblogs.com/zhoutk/archive/2012/10/16/2725328.html
