#include <iostream>

class Stack {
private:
    std::vector<int> data;

public:
    // Push: Add an item to the top of the stack
    void push(int item) {
        data.push_back(item);
    }

    // Pop: Remove and return the top item
    int pop() {
        if (!isEmpty()) {
            int top = data.back();
            data.pop_back();
            return top;
        } else {
            // Handle underflow (stack is empty)
            std::cerr << "Stack underflow!" << std::endl;
            return -1; // Return a default value (you can choose an appropriate value)
        }

    // isEmpty: Check if the stack is empty
    bool isEmpty() {

    // size: Return the number of items in the stack

int main() {
    Stack myStack;

    myStack.push(10);

    std::cout << "Stack size: " << myStack.size() << std::endl;
    std::cout << "Popped item: " << myStack.pop() << std::endl;
    std::cout << "Stack size after pop: " << myStack.size() << std::endl;
