使用堆栈

Question

我正在学习与我学习堆栈的成员函数有问题。我不能使用模板，这就是我遇到问题的原因。我相信我似乎无法正确创建tempStack。我尝试使用Element300和Stack300都给了我不同的编译器错误。如果我能得到一些很好的帮助。如果您发现任何其他错误，请告诉我。我的朋友遇到push功能问题。由于我对tempStack的问题，我无法帮助他。

标题文件：

    typedef float Element300;

class Stack300
{
    private:
        const int MAX_STACK;
        Element300 * stackArray;
        int top;

    public:
        Stack300();//
        Stack300(int);//
        Stack300(Stack300 &);//
        ~Stack300();//
        void push300(const Element300);//
        Element300 pop300();//
        void viewTB300();
        void viewBT300();
        bool isFull();//
        bool isEmpty();//
    };

会员职能：

    using namespace std;


Stack300::Stack300(): MAX_STACK(3)
{
    stackArray = new(std::nothrow) Element300[MAX_STACK];
    if(stackArray == NULL)
    {
        cerr << "There is not enough memory for this stack. This stack will not be implemented correctly." << endl;
    }
    else
    {
    top = -1;
    }
}

Stack300::Stack300(int size): MAX_STACK(size)

    stackArray = new Element300[MAX_STACK];
    top = -1;
}

Stack300::Stack300(Stack300 & old)
{
    Element300 * tempStack;
    int tempTop = -1;
    Element300 tempValue;
    int tempSize = old.MAX_STACK;

    tempStack = new(std::nothrow) Element300[tempSize];

    while(tempTop <= old.MAX_STACK)
    {
        tempValue = old.pop300();
        tempStack.push300(tempValue);
    }

    while(top <= tempStack.MAX_STACK)
    {
        tempValue = tempStack.pop300();
        old.push300(tempValue);
    }

}
Stack300::~Stack300()
{
    Element300 tempValue;

    while(!isEmpty())
    {
        tempValue = pop300();
    }

    if(isEmpty())
    {
        delete [] stackArray;
    }
}

void Stack300::push300(const Element300 number)
{
    if(isFull())
    {
        cerr << "The stack is full." << endl << "The push was unsuccessful" << endl;
    }
    else
    {
        top++;
        stackArray[top] = number;
    }
    return;

Element300 Stack300::pop300()

    Element300 number = 0.0;

    if(isEmpty())

}

void Stack300::viewTB300()
{
    Element300 * tempStack = new (std::nothrow)Element300[MAX_STACK];
    Element300 tempValue;

    while(top > 0)
    {

        cout << tempValue << endl;
        push300(tempValue);
    }

}

bool Stack300::isFull()
{
    bool status;

    if(top == MAX_STACK - 1)
        {
            status = true;
        }
    else
    {
        status = false;
    }

    return status;
}

bool Stack300::isEmpty()
{
    bool status;

    if(top == - 1)
    {
        status = true;
    }
    else
    {
        status = false;
    }

    return status;
}

这也是我得到的错误：
