用C++编写显示年月日程序

#include<iostream> using namespace std; class Date { private: int year; int month; int day; public: Date(int y,int m,int d) {year=y;month=m;day=d;} void Set(int y,int m,int d) {year=y;month=m;day=d;} void show() {cout<<year<<"-"<<month<<"-"<<day<<endl;} }; int main() { Date v1(1990,02,14); v1.show(); system("pause"); return 0; }
