2. Enumeration Data Type enum Day {SUN, MON, TUE, WED, THU, FRI, SAT};
Day today;
today = MON;
if (today == FRI)
cout << "We have a quiz or a test!";
else if (today == THU)
cout << “We have a Lab!";
else if (today == SAT)
cout << “Party!";
else
cout << “What to do?”;

3. Switch Statement enum Day {SUN, MON, TUE, WED, THU, FRI, SAT};
Day today;
today = MON;
. . .
switch (today) {
case FRI:
cout << "We have a quiz or a test!";
case THU:
cout << “We have a Lab!";
case SAT:
cout << “Party!";
default:
cout << “What to do?”; }

4. Must BREAK! today = MON; . . . switch (today) { case FRI:
cout << "We have a quiz or a test!";
break;
case THU:
cout << “We have a Lab!";
case SAT:
cout << “Party!";
default:
cout << “What to do?”; }

5. Must BREAK! today = MON; . . . switch (today) { case FRI:
cout << "We have a quiz or a test!";
break;
case THU:
cout << “We have a Lab!";
case SAT: case SUN:
cout << “Party!";
default:
cout << “What to do?”; }

6. Using enum Type in C++ Classes
enum Status {FRESHMAN, SOPHOMORE, JUNIOR, SENIOR};
class StudentType {
private:
string id;
string firstName, lastName;
float gpa;
Status standing;
public:
. . . };

7. C++ String string Standing() const { string s;
if (standing == FRESHMAN)
s = “FRESHMAN”;
else if (standing == SOPHOMORE)
s = “SOPHOMORE”;
else if (standing == JUNIOR)
s = “JUNIOR”;
else
s = “SENIOR”;
return s; }

8. C++ String and Switch string Standing() const { string s;
switch (standing)
case FRESHMAN:
s = “FRESHMAN”;
break;
case SOPHOMORE:
s = “SOPHOMORE”;
case JUNIOR:
s = “JUNIOR”;
default:
s = “SENIOR”; }
return s;

9. C String and Switch void Standing(char s[]) const {
switch ( standing )
case FRESHMAN:
strcpy(s, “FRESHMAN”);
break;
case SOPHOMORE:
strcpy(s, “SOPHOMORE”);
case JUNIOR:
strcpy(s, “JUNIOR”);
default:
strcpy(s, “SENIOR”); }
return;

10. Method Write of Class StudentType
void Write() const {
string status;
Standing(status);
cout << endl << setw(25) << id
<< endl << setw(25) << firstName
<< endl << setw(25) << lastName
<< endl << setw(25) << gpa;
<< endl << setw(25) << status;
return; }
