Question
58. Consider the following subsets of the set of all students: A = set of all computer science majors B = set of all physics majors C = set of all science majors D = set of all female students Using set operations, describe each of the following sets in terms of A, B, C, and D: a. set of all male students who are not physies majors b. set of all science majors who are not computer science majors c. set of all students who are female or science majors d. set of all students who are science majors but are neither computer science nor physics majorsExplanation / Answer
Public:
Patient ( const char *, const char * , const char *, Date, int);
~Patient();
Patient & setID ( const char * ); //check if length of name string is < 32 if not, shorten to 32 letters.
Patient & setFirstName ( const char *); //check if length of name string is <15, if not, shorten to 14 letters.
Patient & setLastName ( const char *); //check if length of name string is <15, if not, shorten to 14 letters.
Patient & setBirthDate ( Date);
Patient & setPrimaryDoctorID (int);
const char * getID();
const char * getFirstName();
const char * getLastName();
Date getBirthDate();
int getPrimaryDoctorID();
bool enterProcedure(Date procedureDate, int procedureID,int procedureProviderID);
void printAllProcedures();
private:
char ID[33];
char firstName[15];
char lastName [15];
Date birthdate;
int primaryDoctorID;
procedure record[100];
int currentCountOfProcedures; // keeps track of how many procedures have been recorded if it reaches 500, no new procedures // can be entered.
};

For the Date class, you may copy what is at the end of this assignment with the following changes:
void operator+=(int); // Does not return anything
bool leapYear( ) const; // is the year for the date object a leap year?
bool endOfMonth( ) const; // is the date of the object the last day of the month?
~~~
