You can only add an element to the top of the Stack, and
You can only read or remove an element also from the top.
Please use a vector to implement a Stack

#include <vector>
using namespace std;

class EmptyStackException {};

template <typename E>
class Stack
{
private:
vector<E> elements;

public:

void addFirst(const E & elem);
E removeFirst();
};

#include "source"

#include <iostream>
using namespace std;
代写
int main() {
Stack<int> stack;
for (int i = 0; i < 9; ++ i) {
int value;
cin >> value;
stack.addFirst(value);
}
for (int i = 0; i < 9; ++ i) {
cout << stack.removeFirst() << " ";
}
}
