The CovidPatient module

This module has one integer global variable callednextCovidTicketthat is initialized toone. This global variable will be used to determine what is the ticket number of the next COVID test Patient. Each time a newCovidPatientobject is created the value of thenextCovidTicketwill be increased byone. The scope of the globalnextCovidTicketvariable is only theCovidPatientmodule to make sure that the ticket numbers of Covid patients are kept separate from the Triage patients.

TheCovidPatientclass is publicly derived from thePatientclass. TheCovidPatientclass does not add any member variables or properties to thePatientmodule.

TheCovidPatientclass has onedefault constructor, implements the pure virtualtype()function and re-implements the tworeadfunctions and thewritefucniton of the base classPatientas follows:

Default Constructor

Sets the Ticket number to the current global value and then increases the global value by one.

implementation

The default constructor passes thenextCovidTicketglobal variable to theconstructorof the base classPatientand then it will increase the value ofnextCovidTicketglobal variable byone.

The type() virtual function

Identifies the Patient object as a Covid patient by returning the letterC.

implementation

This function only returns the character'C';

csvRead virtual function override

Reads a comma-separated record of a Patient and sets the global ticket number to the next number after the Patient's ticket number.

implementation

First this function will call thecsvReadfunction of the base classPatient, afterwards it will set thenextCovidTicketglobal variable to the return value of thenumber()function of thePatientclass plusone. Then it will ignore the terminating'n'character. Finally, it will return the istream reference.

write virtual function override.

Based on the return value of thefileIOmethod it will either write the patient in a comma-separated format or a descriptive format for screen or ticket.

implementation

If thefileIOmember function returnstrue, it will call thecsvWritefunction of the base class, otherwise it will first insert"COVID TEST"into theostreamobject and goes tonewline. Then it will call thewrite()function of the base class and then goes tonewline.

Then it will end the function by returning theostreamreference.

read virtual function override.

Based on the return value of thefileIOmethod it will either read the patient in a comma-separated format from istream or perform a fool-proof entry from the console.

implementation

If thefileIOmember function returns true it will call thecsvReadfunction, otherwise, it will call the read function of the base class.

Then it will end the function by returning theistreamreference.

Destructor

This class does not need a destructor.

The TriagePatient Module

This module has one integer global variable callednextTriageTicketthat is initialized toone. This global variable will be used to determine what is the ticket number of the next triage Patient. Each time a newTriagePatientis created the value of thenextTriageTicketwill be increased byone. The scope of the globalnextTriageTicketvariable is only the TriagePatient module.

TheTriagePatientclass is publicly derived from thePatientclass. TheTriagePatientclass adds only one character pointer member variable to thePatientmodule to dynamically hold the symptoms of the arriving patient for the triage centre.

TheTriagePatientclass has onedefault constructor, implements the pure virtualtype()function and re-implements the fourread and writefunctions of the base classPatient. It also has a destructor to make sure the dynamically allocated memory by the symptoms character array is deleted.

Symptoms character pointer member variable

DO a character pointer member variable to point to a dynamically allocated Cstring holding the list of the symptoms of the TriagePatient.

Default Constructor

Initializes the symptoms character pointer to null and then sets the Triage Ticket number to the current global value and then increases the global value by one.

implementation

The default constructor initializes the character pointer member variable to null and then passes thenextTriageTicketglobal variable to theconstructorof the base classPatientand then it will increase the value ofnextTriageTicketglobal variable byone.

the type() virtual function

Identifies the Patient object as a Triage patient by returning the letterT.

implementation

This function only returns the character'T';

csvWrite virtual function override.

Adds the symptoms to the comma-separated values of the patient.

implementation

This function calls thecsvWritefunction of the base classPatientthen inserts a comma (',') character into the ostream object and then the symptoms of the patient. Finally, it returns theostreamreference.

the csvRead virtual function override

Reads a comma-separated record of a triage Patient and sets the global ticket number to the next number after the Patient's ticket number.

implementation

csvRead reads the TriagePatient's comma-separated information as follows:

• Deletes the memory pointed by thesymptoms member variable
• Calls thecsvReadfunction of the base class.
• Ignores a character (comma).
• Dynamically reads a Cstring from the istream object up to'n', then extracts the'n'from the istream and stores the address in thesymptoms member variable;
• sets thenextTriageTicketglobal variable to the return value of the number() member function of the Patient class plus one.
• returns the istream reference.

write virtual function override.

Based on the return value of thefileIOmethod it will either write the patient in a comma-separated format or a descriptive format for screen or ticket.

implementation

If thefileIOmember function returnstrue, it will callcsvWritefunction. otherwise, it will write the TriagePatient as follows:

• Inserts"TRIAGE"into theostreamobject.
• Goes tonewline.
• It will call thewrite()function of the base classPatient.
• Goes tonewline.
• Inserts"Symptoms: "into the ostream object.
• Inserts the symptoms member variable into the ostream object.
• Goes to newline.

The function ends by returning theostreamreference.

read virtual function override.

If thefileIOmember function returns true it will call thecsvReadfunction, otherwise, it will do the following:

• Deletes the memory pointed by thesymptoms member variable
• Calls theReadfunction of the base classPatient.
• prompts:"Symptoms: "-Dynamically reads a Cstring from the istream object up to'n', then extracts the'n'from the istream and stores the address in thesymptoms member variable

The function ends by returning theistreamreference.

Destructor

Deletes the memory pointed by thesymptoms member variable
