would love some help with this... I've been doing a lot of imperative langue with c and need a little refresh on OOP

***************patient.cpp below*************

#include "patient.h"

#include

#include

using namespace std;

// Q1 Patient (2 points)

// Patient() constructor assigns the following default values to class data members

// name: abc

// age: 19

// DOByear: 2000

// ID: 0

Patient::Patient()

{

}

// Q2 (18 points)

// 2 points for each function

// Define all the class member functions.

// While defining member functions, note that these functions will be called using

// a 'Patient' object which will represent one patient.

// Eg- Patient p[10]; creates 10 Patient objects

// p[2].setAge(19); will set 3rd patient's age to 19

// setName assigns 'name_input' to class data member 'name'

void Patient::setName(string name_input)

{

}

// setAge assigns age_input to class data member 'age'

void Patient::setAge(int age_input)

{

}

// setDOByear assigns 'DOByear_input' to class data member 'DOByear'

void Patient::setDOByear(int DOByear_input)

{

}

// setID assigns 'ID_input' to class data member 'ID'

void Patient::setID(int ID_input)

{

}

// displayPatients displays the name, age, year of birth and ID of the paatient

// See expected output in question file.

void Patient::displayPatient()

{

}

// getName returns the class data member 'name'.

string Patient::getName()

{

// enter code here

return name;

}

// getAge returns the class data member 'age'.

int Patient::getAge()

{

// enter code here

}

// getDOByear returns the class data member 'DOByear'.

int Patient::getDOByear()

{

// enter code here

}

// getID returns the class data member 'ID'.

int Patient::getID()

{

// enter code here

}
