c++代码已经找不出错误但是还运行不了

#include
using namespace std;
class Date{
public:
void setDate(int y,int m, int d);
void showDate0;
private:
int year;
int month;
int day;
}
void Date: setDateinty,intm,intd)
{year=y; month=m;day=d;}
void Date: showDateO
{cout<<endk<<year<<"."<<month<<"."<<day<<endl;}

注意命名相同和类作用域运算符，在main函数中调用

兄弟你语句不对啊
修改一下:
void Date::setDate(int y,int m,int d)
{year=y; month=m;day=d;}
类里面void showDate();
类外void Date::showDate()
{cout<<year<<"."<<month<<"."<<day<<endl;}
