C++/Data Type/enum

demonstrates enumerations

<source lang="cpp">

1. include <iostream>

 using namespace std;   
   
 const int jack = 11;
 const int queen = 12;   
 const int king = 13;   
 const int ace = 14;   
   
 enum Suit { clubs, diamonds, hearts, spades };   
 struct card{   
    int number;
    Suit suit; 
   };   
 int main()   
    {   
    card temp, chosen, prize; 
    int position;   
   
    card card1 = { 7, clubs };
    cout << "Card 1 is the seven of clubs\n";   
   
    card card2 = { jack, hearts };
    cout << "Card 2 is the jack of hearts\n";   
   
    card card3 = { ace, spades }; 
    cout << "Card 3 is the ace of spades\n";   
   
    prize = card3;              
   
    if(chosen.number == prize.number &&  chosen.suit == prize.suit)   
       cout << "That"s right!  You win!\n";   
    else   
       cout << "Sorry. You lose.\n";   
    return 0;   
 }

demonstrates enums, counts words in phrase

<source lang="cpp">

1. include <iostream>

 using namespace std;   
 #include <conio.h>
   
 enum itsaWord { NO, YES };
   
 int main(){   
    itsaWord isWord = NO;       
    char ch = "a";            
    int wordcount = 0;        
   
    cout << "Enter a phrase:\n";   
    do {   
       ch = getche();         
       if(ch==" " || ch=="\r"){   
          if( isWord == YES ){                 
             wordcount++;      
             isWord = NO;      
          }   
       }else if( isWord == NO ){
          isWord = YES;     
       }
    } while( ch != "\r" );     
    cout << wordcount;   
    return 0;   
 }
 
   
   
 </source>

demonstrates enum types

<source lang="cpp">

1. include <iostream>

 using namespace std;   
 enum days_of_week { Sun, Mon, Tue, Wed, Thu, Fri, Sat };   
   
 int main() {   
    days_of_week day1, day2;  
                              
    day1 = Mon;               
    day2 = Thu;               
   
    int diff = day2 - day1;   
    cout << "Days between = " << diff << endl;   
   
    if(day1 < day2)           
       cout << "day1 comes before day2\n";   
    return 0;   
 }

Using bit fields.

<source lang="cpp">

1. include <iostream>
2. include <string.h>

using namespace std; enum STATUS { FullTime, PartTime } ; enum GRADLEVEL { UnderGrad, Grad } ; enum HOUSING { Dorm, OffCampus }; enum FOODPLAN { OneMeal, AllMeals, WeekEnds, NoMeals }; class student {

public:
student():
    myStatus(FullTime),
    myGradLevel(UnderGrad),
    myHousing(Dorm),
    myFoodPlan(NoMeals)
    {}
    ~student(){}
    STATUS GetStatus();
    void SetStatus(STATUS);
    unsigned GetPlan() { return myFoodPlan; }
private:
   unsigned myStatus : 1;
   unsigned myGradLevel: 1;
   unsigned myHousing : 1;
   unsigned myFoodPlan : 2;
};
STATUS student::GetStatus()
{
   if (myStatus)
      return FullTime;
   else
      return PartTime;
}
void student::SetStatus(STATUS theStatus)
{
   myStatus = theStatus;
}

int main()
{
   student Jim;
   if (Jim.GetStatus()== PartTime)
      cout << "Jim is part time" << endl;
   else
      cout << "Jim is full time" << endl;
   Jim.SetStatus(PartTime);
   if (Jim.GetStatus())
      cout << "Jim is part time" << endl;
   else
      cout << "Jim is full time" << endl;
   cout << "Jim is on the " ;
   char Plan[80];
   switch (Jim.GetPlan())
   {
      case  OneMeal: strcpy(Plan,"One meal"); break;
      case  AllMeals: strcpy(Plan,"All meals"); break;
      case WeekEnds: strcpy(Plan,"Weekend meals"); break;
      case NoMeals: strcpy(Plan,"No Meals");break;
      default : cout << "Something bad went wrong!\n"; break;
   }
   cout << Plan << " food plan." << endl;
 return 0;

}

Using consts and enums in Arrays

<source lang="cpp">

1. include <iostream>

int main() {

   enum WeekDays { Sun, Mon, Tue,Wed, Thu, Fri, Sat, DaysInWeek };
   int ArrayWeek[DaysInWeek] = { 10, 20, 30, 40, 50, 60, 70 };
  std::cout << "The value at Tuesday is: " << ArrayWeek[Tue];
  return 0;

}
