请看下面的代码,
堆栈.h
template <typename T>
class Stack
{
public:
Stack(int number)
{
maxSize = number;
top = -1;
stackData = new T*[maxSize];
}
~Stack()
{
delete [] stackData;
}
int count()
{
}
bool isEmpty()
{
if(top==-1)
{
return true;
}
else
{
return false;
}
}
bool isFull()
{
if(top== (maxSize-1))
{
return true;
}
else
{
return false;
}
}
*T pop()
{
if(!isEmpty())
{
return stackData[top--]; // Remove Item From Stack
}
}
*T peek()
{
T *peekData = &stackData[top];
return peekData;
}
void push(T *pushValue)
{
if(!isFull())
{
stackData[++top] = pushValue;
}
}
private:
int maxSize;
T ** stackData;
int top;
};
主文件
#include <iostream>
#include "Stack.h"
#include <iostream>
using namespace std;
int main()
{
int i = 0;
Stack<double> doubleStack(5);
double doubleValue = 1.1;
cout << "pushing elements into the stack" << endl;
while(i<5)
{
doubleStack.push();
}
system("pause");
return 0;
}
当我运行此代码时,我收到以下错误。

Intellelisense 不识别除 isFull()、count() 和 isEmpty() 之外的任何方法。因为这个,我无法编写其余的代码!
为什么是这样?请帮忙!
