枚举变量二

#include <iostream>
using namespace std;
enum Weekday {Sunday,Monday,Tuesday,Wednesday,Thresday,Friday,Saturday};
void main()
{
    Weekday day1,day2;
    day1=Monday;
    day2=Saturday;
    int n;
    n=day1;
    n=day2+1;
    if(n>day1)//可以比较
        cout << "n>day1" <<endl;
    if(day1<day2)
        cout << "day1<day2" <<endl;
}

#include <iostream>
using namespace std;
void main()
{
    enum  weekday{Sunday=2,Monday=3,Tuesday=4,Wednesday=5,Thursday=0,Friday=1,Saturday=6};

    weekday m_eType1;
    weekday m_eType2;
    m_eType1=Sunday;//Sunday=2
    m_eType2=Friday;//Friday=1
    cout << m_eType1-m_eType2 << endl;
