C++每日打卡

定义一个Tree(树)类,有成员ages(树龄),不带参数的构造函数对ages初始化为1,成员函数grow(int years)对ages加上years,age()显示tree对象的ages的值。

 

#include <iostream>
using namespace std;

class Tree {
public:
Tree();//构造函数
void grow(int years);//对数龄ages加上years
void age();//显示数龄ages的值
private:
int ages;//树龄
};

Tree::Tree():ages(1)
{

}
void Tree::grow(int years)
{
ages=ages+years;
}
void Tree::age()
{
cout<<ages;
}

int main()
{
Tree tree;
int years;
cin >> years;
tree.grow(years);
tree.age();

return 0;
}
