Question

C++

Write a class Fraction that defines adding, subtracting, multiplying, and dividing fractions by overloading standard operators for these operations. Write a function member for reducing factors and overload I/O operators to input and output fractions

Answer 1

#include<iostream>
using namespace std;
//a class Fraction that defines adding, subtracting, multiplying, and dividing fractions
class Fraction

{

private:
//these are the variables for numberator and denominator of a fraction
int numerator, denominator;

public:
//this is contstrutor
Fraction(int n = 1, int d = 2) : numerator(n), denominator(d)
{

}
//to print fraction
void printFraction()
{
   cout<<numerator<<"/"<<denominator;
}
//overloading standard operators for adding, subtracting, multiplying, and dividing operations
//overload I/O operators to input and output fractions
Fraction operator+(Fraction frac) const

{
   return Fraction(numerator+frac.numerator, denominator+frac.denominator);
}

Fraction operator-(Fraction frac) const

{
   return Fraction(numerator-frac.numerator, denominator-frac.denominator);
}

Fraction operator*(Fraction frac) const

{
   return Fraction(numerator*frac.numerator, denominator*frac.denominator);
}

Fraction operator/(Fraction frac) const

{

int rnumerator = (frac.denominator*numerator)/denominator;

return (rnumerator, frac.numerator);

}

friend ostream& operator<<(ostream& out, Fraction& frac)

{
   cout<<frac.numerator<<"/"<<frac.denominator;
   return out;
}

friend istream& operator>>(istream& in, Fraction& frac)

{

cout<<"\nEnter numeratorerator: "; cin>>frac.numerator; cout<<"Enter denominatorominator: ";

cin>>frac.denominator; cout<<frac.numerator<<"/"<<frac.denominator;

return in;

}

int findMax()

{
   if(numerator<=denominator) return numerator;
   else return denominator;
}

//a function member for reducing factors
void reduceFraction()

{

for(int i = 2; i<=findMax(); i++)

if(numerator%i == 0 && denominator%i == 0)

{
   numerator = numerator/i;
   denominator = denominator/i;
   i = 1;
}

}

}; //

int main()

{

Fraction frac1(5, 6);

Fraction frac2(80, 1001);

cout<<"fraction1 :"<<frac1<<"\nfraction2 :"<<frac2<<endl;

Fraction frac3 = frac1/frac2;

frac3.reduceFraction(); cout<<"fraction3 :"<<frac3;

cout<<endl;

return 0;
