给我用cplus语言写一个栈

好的，这是一个简单的 C++ 栈的实现：

#include <iostream>
using namespace std;

const int MAX_SIZE = 100;

class Stack {
private:
    int top;
    int data[MAX_SIZE];
public:
    Stack() {
        top = -1;
    }
    bool isEmpty() {
        return top == -1;
    }
    bool isFull() {
        return top == MAX_SIZE - 1;
    }
    void push(int value) {
        if(isFull()) {
            cout << "Stack is full." << endl;
            return;
        }
        top++;
        data[top] = value;
    }
    int pop() {
        if(isEmpty()) {
            cout << "Stack is empty." << endl;
            return -1;
        }
        int value = data[top];
        top--;
        return value;
    }
};

int main() {
    Stack s;
    s.push(1);
    s.push(2);
    s.push(3);
    cout << s.pop() << endl;
    cout << s.pop() << endl;
    cout << s.pop() << endl;
    cout << s.pop() << endl;
    return 0;
}
