Question

This lab will exercise your understanding of some of the concepts covered in Chapter 12: virtual functions (think about compile-time and run-time binding) 1. We will be treating the PersonType object as a base class that may be inherited by multiple objects. We will treat the personType getAddress and setAddress as pure virtual because we wish to have all inherited objects to code these functions but do not need them in the base class. Using the code for person type provided in program examples do the following: a. Make the following function a pure virtual function: print . This function must remain const. b. Create the following functions as pure virtual functions: getAddress setAddress 2. For the purpose of this lab, we will create only one inherited Class: StudentType. Create the class, inherited as public from Persontype with the following properties: a. Private data members: major id gpa address (just one string address) b. Create the proper public functions to properly access and set private data members. Create a default constructor and an overloaded constructor to set ALL data member values. c. Overload the proper functions to retrieve, set, and process data members of the base class d. Create two studentType objects: One using the default constructor. Set all private and inherited data members using functions. One using the overloaded constructor, which sets all the private and inherited data members e. Print the following for the student objects: First Name Last Name Major Id GPA Address Complete as much as you can before you leave ensuring what you've completed compiles. These labs are entirely for your practice. You DO NOT have to comment these programs, however, please include your NAME as a comment in ALL code files. SUBMIT the code ( *.h and *.cpp) files and the project file (*.dev or *.cbp)

Answer 1

Below are the screenshots of code & output.

Below is the C++ code for the same. I have not put comments in code, since the instructions in question restricted me from doing so. Here, I have created two classes PersonType and StudentType as metioned in the question. All the virtual functions have been created in base class PersonType and implemented in inherited class StudentType.

The PersonType has member variables - 'Name' & 'address', which are inherited by StudentType. In StudentType class, various member variables are used; also, both the default and the overloaded constructor are implemented. Also setters and getters are implemented for accessing and setting member variables.

Finally in main function, two objects are created- one using default constructor whose member variables are then set using setter functions, and other using overloaded constructor. Both the objects are printed after creation.

#include <bits/stdc++.h>

using namespace std;

class PersonType

{

protected:

string Name,address;

public:

virtual string getAddress(){ return "";}

virtual void setAddress(string s){}

virtual void print(){}

};

class StudentType:public PersonType

{

private:

string major,id;

double gpa;

public:

StudentType(){}

StudentType(string n,string m,string i,double g,string a){

Name=n;

major=m;

id=i;

gpa=g;

address=a;

}

void setName(string s){

Name=s;

}

void setMajor(string s){

major=s;

}

void setId(string s){

id=s;

}

void setGpa(double s){

gpa=s;

}

void setAddress(string s){

address=s;

}

string getName() {

return Name;

}

string getMajor(){

return major;

}

string getId() {

return id;

}

double getGpa() {

return gpa;

}

string getAddress() {

return address;

}

string getFirstName(){

return Name.substr(0,Name.find(" "));

}

string getLastName(){

return Name.substr(Name.find(" ")+1);

}

void print(){

printf(" ______________ ______________ ________________________ ____________ _______ _________________ \n");

printf("| First Name | Last Name | Major | ID | GPA | Address |\n");

printf("|______________|______________|________________________|____________|_______|_________________|\n");

printf("| %12s | %12s | %22s | %10s | %5.2f | %15s | \n",getFirstName().c_str(),getLastName().c_str(),major.c_str(),id.c_str(),gpa,address.c_str());

printf("|______________|______________|________________________|____________|_______|_________________|\n\n");

}

};

int main()

{

StudentType s1=StudentType();

s1.setName("Tony Stark");

s1.setMajor("Computer Science");

s1.setId("UCO1555");

s1.setGpa(3.5);

s1.setAddress("New York");

s1.print();

StudentType s2=StudentType("John Wick","Information Technology","UIT2008",4.87,"California");

s2.print();
