#include <iostream>
using namespace std;
int main()
{

   enum day{sunday,monday,tuesday,wednesday,thursday,friday,saturday};
   day today;
   today = saturday;
   if(today == sunday||today == saturday)
       cout<<"周末"<<endl;
   else
       cout<<"工作日"<<endl;
    return 0;
}

例如：

#include <iostream>
using namespace std;
enum weektype
{
    monday ,
    tuesday ,
    wednesday,
    thursday,
    friday,
    saturday,
    sunday
};
void go(weektype wt)
{
    switch (wt) {
    case monday:
    cout<<"今天是周一"<<endl;
        break;
    case tuesday:
    cout<<"今天是周二"<<endl;
        break;
    case wednesday:
    cout<<"今天是周三"<<endl;
        break;
    case thursday:
    cout<<"今天是周四"<<endl;
        break;
    case friday:
    cout<<"今天是周五"<<endl;
        break;
    case saturday:
    cout<<"今天是周六"<<endl;
        break;
    case sunday:
    cout<<"今天是周日"<<endl;
        break;
    default:
        break;
    }
}
int main()
{
    go(weektype::monday);
    go(weektype::sunday);
    system("pause");
}
