如果模板中存在成员函数指针，如何获取

#include <iostream>
#include <functional>

class MyClass {
public:
    void memberFunc(int value) {
        std::cout << "Member function called with value: " << value << std::endl;
    }
};

int main() {
    MyClass obj;
    auto func = std::mem_fn(&MyClass::memberFunc);
    func(obj, 42);  // 调用成员函数
    return 0;
}

#include <iostream>

class MyClass {
public:
    void memberFunc(int value) {
        std::cout << "Member function called with value: " << value << std::endl;
    }
};

int main() {
    MyClass obj;
    auto func = [&obj](int value) { obj.memberFunc(value); };
    func(42);  // 调用成员函数
    return 0;
}
