#include <iostream>

int main() {
	//枚举的定义
	//enum中的数据实为整型int.
	//默认情况下这些枚举值从0开始,依次+1递增
	enum day {Sun,Mon,Tue,Wed,Thu,Fri,Sat};
	enum day sunDay;
	enum day monDay;
	enum day tueDay;
	sunDay=Sun;
	monDay=Mon;
	tueDay=Tue;
	cout<<"sunDay="<<sunDay<<endl;
	cout<<"monDay="<<monDay<<endl;
	cout<<"tueDay="<<tueDay<<endl;
	cout<<"--------------------"<<endl;

	//也可指定枚举开始的值.
	//其后的值依次+1递增
	enum number {Number1=9527,Number2,Number3,Number4};
	enum number num1=Number1;
	enum number num2=Number2;
