Question

Submission Instruction Complete the following C++ programs. The assignment contains only one file with all different class and functions from problem 1. The main function calls different functions as instructed in the problem description. Submit the CPP file during submission Problem 1. Define a class for a type called Fraction. This class is used to represent a ratio of two integers. Include mutator functions that allow the user to set the numerator and the denominator (one for each data). Also include a member function that returns the value of the numerator divided by the denominator as a double. Include an additional member function that outputs the value of the fraction reduced to lowest terms (simplest form). For example, instead of outputting 20/60 the function should output 1/3. This will require finding the greatest common divisor for the numerator and denominator and then dividing both by that number. Embed your class in a test program where you create 2 fractions with user data and display their two values.

Answer 1

#include <iostream>
using namespace std;

class Fraction
{
private:
int numerator;
int denominator;

public:
Fraction() //default constructor
{
numerator = 0;
denominator = 1;
}
Fraction(int num,int den) //argument constructor
{
if(denominator != 0)
{
numerator=num;
denominator=den;
}
simplify();
}

  
     friend std::ostream& operator<<( std::ostream &output, const Fraction &F )
     {
       output << F.numerator << " / " << F.denominator;
         return output;
     }
    
      double toDouble()
      {
       return (double)numerator/denominator;
      }
     
     
      int gcd(int x, int y) // compute greatest common divisor
      {
       int t;
while (y>0) {
t = x % y;
x = y;
y = t;
}
return x;
      }
    
       void simplify() {
int factor;
factor = gcd(numerator, denominator);
numerator = numerator / factor;
denominator = denominator / factor;
}

int getNumerator()
{
return numerator;
}

int getDenominator()
{
return denominator;

}

};
int main()
{
Fraction r1(20,60);
Fraction r2(30,40);

cout<<"Fraction f1 : "<<r1.getNumerator()<<"/"<<r1.getDenominator();
cout<<"\nFraction f1 in decimal : ";
cout<<r1.toDouble();

cout<<"\nFraction f2 : "<<r2.getNumerator()<<"/"<<r2.getDenominator();
cout<<"\nFraction f2 in decimal : ";
cout<<r2.toDouble();

return 0;
}

Output:

Fraction f1 : 1/3
Fraction f1 in decimal : 0.333333
Fraction f2 : 3/4
Fraction f2 in decimal : 0.75
