设计带构造函数的Dog类 代码参考

 #include <iostream>
 #include <string>

 using namespace std;

 class Dog
 {
     private:
         string name;
         int age;
         char sex;
         double weight;
     public:
         Dog(string,int,char,double);
         void GetName(){cin>>name;return;}
         void GetAge(){cin>>age;return;}
         void GetSex(){cin>>sex;return;}
         void GetWeigth(){cin>>weight;return;}
         void speak(){cout<<"Arf!Arf!"<<endl;return;}
         void show()
         {
             cout<<name<<endl;
             cout<<age<<endl;
             cout<<sex<<endl;
             cout<<weight<<endl;
             return;
         }
 };

 Dog::Dog(string name, int age, char sex, double weight)
 {
     this->name=name;
     this->age=age;
     this->sex=sex;
     this->weight=weight;
 }

 int main()
 {
     string name;
     int age;
     char sex;
     double weight;
     cin>>name>>age>>sex>>weight;
     Dog one(name,age,sex,weight);
     one.show();
     one.speak();
     return ;
 }
