stack类模板练习

以前老听到同学这样抱怨“程序和书上一模一样，为什么会有这么多错误？”今年用的C++已经是我见怪不怪了~~下面是一个stack类模板练习
#include
using namespace std;

template
class Stack {
private :
T* date;
int size;
int top;
int IsFull () { return (top >= size )? 1: 0; }
public:
Stack (int n ) { date = new T[n];size = n; top =0; }
~Stack () {delete date; }
T pop ();
void push (T a);
int IsEmpty () { return (top <= 0 )? 1: 0; }
void print();
};

template
void Stack::push (T a)
{
if (IsFull ())
{
cout << “Stack overflown”;
return;
}
*(date + top++) = a;
}
template
inline T Stack::pop ()
{
if (IsEmpty ())
{
cout << “Stack underflown”;
}
return (*(date + –top));
}
template
void Stack::print(){
while (!IsEmpty()){
cout << pop() << ‘t’;
}
cout << endl;
}

int main()
{
Stack x (5);
x.push (1);
x.push (2);
x.push (3);
x.push (4);
x.push (5);

x.print();

Stack y (5);
y.push (‘a’);
y.push (‘b’);
y.push (‘c’);
y.push (‘d’);
y.push (‘e’);

y.print();

return 0;
}
