使用函数指针数组调用类的方法

#include <iostream>

class MyClass {
public:
    void method1() {
        std::cout << "This is method 1." << std::endl;
    }

    void method2() {
        std::cout << "This is method 2." << std::endl;
    }
};

int main() {
    typedef void (MyClass::*MethodPtr)();  // 定义函数指针类型

    MethodPtr methods[] = {&MyClass::method1, &MyClass::method2};  // 定义函数指针数组

    MyClass obj;
    int choice;

    std::cout << "Enter 1 to call method 1, 2 to call method 2: ";
    std::cin >> choice;

    if (choice >= 1 && choice <= 2) {
        (obj.*methods[choice - 1])();  // 使用函数指针数组调用类的方法
    } else {
        std::cout << "Invalid choice." << std::endl;
    }

    return 0;
}
