这个是我们数据结构第三个实验的源代码,在这里和大家一起分享

include<iostream>
using namespace std;
class date
{
     int yy;
     int mm;
     int dd;
public:
    void set(int a,int b,int c);
    void print(char a,int b);
};
void date::set(int a,int b,int c)
{
        yy=a;
        mm=b;
        dd=c;
}
void date::print(char a,int b)
{
    if(b==1) 
    {
        if(yy<10) 
            cout<<'0'<<yy<<a<<mm<<a<<dd;
        else 
            cout<<yy<<a<<mm<<a<<dd;
    }
    else if(b==2) 
    {
        if(yy<10) 
            cout<<mm<<a<<dd<<a<<'0'<<yy;

        else

    }
    else

}
