Write a program in C++ or C that includes two different enumeration types and has a significant number of operations using the enumeration types. Also write the same program using only integer variables. Compare the readability and predict the reliability differences between the two programs.

Enum is a value type data type which is used to declare a list of named integer constants and can be defined using the enum keyword inside a class, or structure. The enum is used to give a name to each constant so that the constant integer can be called using its name. In most case enum provides a better readability than showing some integer values.

Explanation:

Using enum:

#include<iostream>

#include<string>

#include<stdlib.h>

using namespace std;

enum TempLevel { Low = 15, Medium = 30, High = 45 };

enum TempConverter{ Celsius = 1, Fahrenheit };

void TempLevel(int convertedValue);

int main()

{

while (true)

{

TempConverter Converter;

int userInput, choice, convertedValue;

cout << "" << endl;

cout << "Please enter the choice : " << endl;

cout << "Enter " << Celsius << " -- convert from Celsius to Fahrenheit" << endl;

cout << "Enter " << Fahrenheit << " -- convert from Fahrenheit to Celsius" << endl;

cout << "Choice :";

cin >> choice;

switch (choice)

{

case Celsius:

cout << "Please enter the Celsius value : ";

cin >> userInput;

convertedValue = (userInput * 9 / 5) + 32;

cout << "Fahrenheit is " << convertedValue << endl;

TempLevel(userInput);

break;

case Fahrenheit:

cout << "Please enter the Fahrenheit value : ";

cin >> userInput;

convertedValue = (userInput - 32) * 5 / 9;

cout << "Celsius is " << convertedValue << endl;

TempLevel(convertedValue);

break;

default:

cout << "Invalid Option" << endl;

exit(0);

break;

}

}

}

void TempLevel(int convertedValue)

{

string result;

convertedValue <= Low ? result = "Temperature is cold" : "";

convertedValue > Low && convertedValue <= Medium ? result = "Temperature is comfort" : "";

convertedValue > Medium && convertedValue <= High ? result = "Temperature is hot" : "";

convertedValue > High ? result = "Temperature is very hot" : "";

cout << result << endl;

}

Using integer datatype:

#include <iostream>

#include<string>

#include<stdlib.h>

using namespace std;

void TempLevel(int convertedValue);

int main()

{

while (true)

{

int userInput, choice, convertedValue;

cout << "" << endl;

cout << "Please enter the choice : " << endl;

cout << "Enter 1 -- convert from Celsius to Fahrenheit" << endl;

cout << "Enter 2 -- convert from Fahrenheit to Celsius" << endl;

cout << "Choice :";

cin >> choice;

switch (choice)

{

case 1:

cout << "Please enter the Celsius value : ";

cin >> userInput;

convertedValue = (userInput * 9 / 5) + 32;

cout << "Fahrenheit is " << convertedValue << endl;

TempLevel(userInput);

break;

case 2:

cout << "Please enter the Fahrenheit value : ";

cin >> userInput;

convertedValue = (userInput - 32) * 5 / 9;

cout << "Celsius is " << convertedValue << endl;

TempLevel(convertedValue);

break;

default:

cout << "Invalid Option" << endl;

exit(0);

break;

}

}

}

void TempLevel(int convertedValue)

{

string result;

convertedValue <= 15 ? result = "Temperature is cold" : "";

convertedValue > 15 && convertedValue <= 30 ? result = "Temperature is comfort" : "";

convertedValue > 30 && convertedValue <= 45 ? result = "Temperature is hot" : "";

convertedValue > 45 ? result = "Temperature is very hot" : "";

cout << result << endl;

}
