Question

You are a senior team lead for a fledgling software engineering firm. In order to meet a tight deadline, you have hired a freelance programmer to remotely assist you and your small team. To ensure that this freelancer can deliver usable code, you ask them to submit a simple header file named test.h that contains a definition for a class named Test. You specify that this Test class must contain one private, bool-typed member variable named b and a corresponding pair of public accessor/mutator function declarations. Within 24 hours, this freelancer delivers the following header file:

#ifndef TEST
#define TEST

class Test
{

bool b = true; //Initialized to true by default;

public:

//Accessor function that returns private
//member variable b back to the calling function
bool get_b();

//Mutator function that assigns value of bParam
//to the private member variable b
void set_b(bool bParam);

};

#endif

Implementation

You decide to test the correctness of this class definition by creating two files: an implementation file named test.cpp and a program file named TestProgram.cpp. You #include the above header file in both files

In test.cpp, you perform two tasks:

1) Define the accessor function of the Test class
2. Define the mutator function of the Test class

In TestProgram.cpp, you perform three tasks:

1) Define the main function to create a Test object named tObj
2) In main, call tObj's set_b function, passing in a value of false as the argument
3) In main, print out the value returned by calling get_b to the terminal

Once you perform these tasks, you compile and link TestProgram.cpp with your test.o file. Upon executing your a.out file and verifying that a value of 0 (or false) is output to the terminal, you can reasonably assume that this freelancer has satisfied your baseline requirements.

Answer 1

Given below is the code for the question. Please do rate the answer if it helped. Thank you.

test.h
-----
#ifndef TEST
#define TEST

class Test
{

bool b = true; //Initialized to true by default;

public:

//Accessor function that returns private
//member variable b back to the calling function
bool get_b();

//Mutator function that assigns value of bParam
//to the private member variable b
void set_b(bool bParam);

};

#endif

test.cpp
------

#include "test.h"

bool Test::get_b(){
   return b;
}

void Test::set_b(bool bParam){
   b = bParam;
}

TestProgram.cpp
------
#include <iostream>
#include "test.h"
using namespace std;
int main(){
   Test tObj;
   tObj.set_b(false);
   cout << tObj.get_b() << endl;
   return 0;
}
