访问类成员向量最后一项的正确方式

#include <iostream>
#include <vector>

class MyClass {
public:
    std::vector<int> myVector;

    void printLastItem() {
        if (!myVector.empty()) {
            int lastItem = myVector.back();
            std::cout << "The last item in the vector is: " << lastItem << std::endl;
        } else {
            std::cout << "The vector is empty." << std::endl;
        }
    }
};

int main() {
    MyClass obj;
    obj.myVector = {1, 2, 3, 4, 5};

    obj.printLastItem();

    return 0;
}

The last item in the vector is: 5
