枚举用法enum举例

#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");}
