[問題] 類別、建構子問題

程式新手 前幾天寫了一個練習題拿去問chatgpt #include <iostream> using namespace std; class Animal { public: string name; Animal(string, string, int); void print1(); protected: string type; int weight; }; Animal::Animal(string n, string t, int w) { name = n; type = t; weight = w; } void Animal::print1() { cout << "name:" << name << " type:" << type << " weight:" << weight; } class Cat : public Animal { public: Cat(string, string, int, int, int); void print2(); private: int body_length; int tail_length; }; Cat::Cat(string n, string t, int w, int b, int a) : Animal(n, t, w), body_length(b), tail_length(a) {} void Cat::print2() { print1(); cout << " body length:" << body_length << " tail length:" << tail_length; } class Human : public Animal { public: Human(string, string, int, int, string); void print3(); Cat pet; protected: int height; }; Human::Human(string n, string t, int w, int h, string p) : Animal(n, t, w), height(h) { pet = Cat(p, "black", 7, 30, 20); } void Human::print3() { print1(); cout << " height:" << height << " pet:" << pet.name << endl; } int main() { Human Betty("Betty", "Asian", 46, 160, "Kitty"); Betty.print3(); Betty.pet.print2(); return 0; } 結果竟然沒辦法執行xdd 後來回覆他後他又生了一個程式給我，基本上就是把黃字的部分改成 Human::Human(string n, string t, int w, int h, string p) : Animal(n, t, w), height(h), pet(p, "black", 7, 30, 20) {} 這樣 但是這兩個有什麼不同啊@@他解釋給我聽但是我聽不懂.... 但是這兩個有什麼不同啊@@他解釋給我聽但是我聽不懂.... 請教板上高手！ ---- Sent from BePTT on my OPPO CPH1943 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 180.217.31.86 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/C_and_CPP/M.1695028575.A.715.html
