如何获取重载成员函数的地址？

const type_info& info = typeid(Foo);
cout << "Class name: " << info.name() << endl;
for (size_t i = 0; i < info.num_functions(); i++) {
    cout << "Function " << i << ": " << info.function_name(i) << endl;
}

#include <iostream>
#include <string>
#include <vector>
#include <typeinfo>

class Foo {
public:
    virtual ~Foo() {}
    virtual void foo(int x) {}
    virtual void foo(double x) {}
};

int main() {
    Foo foo;
    type_info& info = typeid(foo);
    std::string className = info.name();
    std::vector<std::string> functionNames = info.function_name(0);

    for (size_t i = 0; i < functionNames.size(); i++) {
        std::string functionName = functionNames[i];
        if (functionName == "foo") {
            std::cout << "Function " << i << ": " << info.name() << " (" << info.signature() << ")" << std::endl;
        }
    }

    return 0;
}
