vc++编译错误 error C2572:请问慕友们该怎么解决？

Question

#include<iostream>using namespace std;class clock{public:void settime(int newh=0,int newm=0,int news=0);void showtime();private:int hour,minute,second;};void clock::settime(int newh=0,int newm=0,int news=0){hour=newh;minute=newm;second=news;}inline void clock::showtime(){cout<<hour<<":"<<minute<<":"<<second<<endl;}int main(){clock m;cout<<"first time set and output"<<endl;m.settime();m.showtime();cout<<"second time set and output"<<endl;m.settime(8,32,41);m.showtime();return 0;}

Answer 1

void clock::settime(int newh=0,int newm=0,int news=0)
{hour=newh;minute=newm;second=news;}
==>
void clock::settime(int newh,int newm,int news)
{hour=newh;minute=newm;second=news;}

Answer 2

重复定义的问题
将Line12改为：void clock::settime(int newh,int newm,int news)就可以了
