a. You have been developing a Fraction class for Teacher’s Pet Software that contains
several fields and functions.
Add two constructors to the class. The first accepts two integer values representing the
numerator and denominator. If a single integer is passed to the constructor, use it as the
numerator, and use a default value of 1 for the denominator. If no values are passed to
the constructor, use a default value of 0 for the numerator and 1 for the denominator.
When any Fraction is constructed with a 0 argument for the denominator, force the
denominator value to 1.
The second constructor requires three arguments: a whole number portion for a Fraction,
a numerator, and a denominator. This constructor executes when any Fraction object
is instantiated using three integer arguments. As with the other constructor, when any
Fraction is constructed with a 0 argument for the denominator, force the denominator
value to 1.
Whenever a Fraction object is constructed, automatically reduce the Fraction to the
proper format. For example, a Fraction created using 0, 2, and 4 as arguments should
be reduced to 1/2, and a Fraction created as 3 10/2 should be reduced to 8 0/1.
Write a main()function that declares several Fraction objects, and confirm that the
class works correctly.
Save the file as Fraction.cpp.
Explanation / Answer
Please find my code:
a) Frction Program
Program
//HeaderFiles
#include<iostream>
#include<math.h>
//For input output(cin,cout)
using namespace std;
//Fraction class
class fraction {
//member variables
int numerator;
int denominator;
double wholenumber;
//You have to declare member functions as public
public:
//Default constructor
fraction();
//Construction with parameters
fraction(double wholenumber, int numerator = 0, int denominator = 1);
//method
void reduceFraction();
};//end of the class
//method definitions
fraction::fraction() {
//put default values to numerator and denominator
numerator = 0;
denominator = 1;
reduceFraction();
}
fraction::fraction(double wholenumber, int numerator, int denominator) {
//set values to numerator,denominator and wholenumber with user given
numerator = numerator;
denominator = denominator;
wholenumber = wholenumber;
reduceFraction();
}
//fraction calculation expansion
void fraction::reduceFraction() {
if (wholenumber == 0) {
for (int index = 0; index = denominator * numerator; index--) {
if ((denominator % index == 0) && (numerator % index == 0)) {
denominator /= index;
numerator /= index;
}
}
}
else {
int number = denominator * wholenumber + numerator;
for (int index = denominator * number; index > 1; index--) {
if ((denominator % index == 0) && (number% index == 0)) {
denominator /= index;
number /= index;
}
}
wholenumber = number / denominator;
numerator = number % denominator;
}
cout << wholenumber << "" << numerator << "/" << denominator;
}
//main function
int main() {
//variable declaration
int numerator;
int denominator;
double wholenumber;
//user prompt
cout << " Program to reduce fraction" << " Enter 0 when you don't want to enter value";
cout << "Enter a whole number";
cin >> wholenumber;
cout << "Enter numerator";
cin >> numerator;
cout << "Enter denominator";
cin >> denominator;
//check denominator
if (wholenumber == 0 && denominator == 0) {
cout << "Denominator has been set to defult value 1";
fraction f(wholenumber, numerator, 1);
}
else if (denominator == 0) {
cout << " Denominator has been set to defult value 1";
fraction(wholenumber, numerator);
}
else
fraction(wholenumber, numerator, denominator);
return 0;
}
