Question

C++定义一个Dog类，包含age，weight，sex等属性以及对这些属性的操作方法，实现并测试这个类

别用太难的啊，别用void

Answer 1

#include <iostream>
#include <string>
using namespace std;

class Dog
{
public:
Dog() {age = 1; sex = "male"; weight = 1.0;}
Dog(int _age, string _sex, double _weight):age(_age), sex(_sex), weight(_weight) {}
~Dog(){}
void setDog(int _age, string _sex, double _weight)
{
age = _age;
sex = _sex;
weight = _weight;
}
void showDog()
{
cout<<"age = "<<age<<", sex = "<<sex.c_str()<<", weight = "<<weight<<endl;
}

private:
int age;
string sex;
double weight;
};

int main()
{
Dog d1, d2(10, "female", 20.0);
d1.showDog();
d2.showDog();

d1.setDog(8, "female", 50);
d1.showDog();

cin.get();
return 0;
}
