write an overloaded friend ostream insertion operator function that allows a Fraction object to be output and appear in the form num/denom, using a cout statement. b. Write an overloaded friend istream extraction operator function that allows fractions in the form a/b to be input and assigned to a Fraction object.

Sure, I can help you with that!

Here is the implementation of the overloaded friend ostream insertion operator function for the Fraction class:

#include <iostream>

class Fraction {
    private:
        int numerator;
        int denominator;
    public:
        Fraction(int num, int denom) : numerator(num), denominator(denom) { }
        friend std::ostream& operator<<(std::ostream& os, const Fraction& frac);
};

std::ostream& operator<<(std::ostream& os, const Fraction& frac) {
    os << frac.numerator << "/" << frac.denominator;
    return os;
}

And here is the implementation of the overloaded friend istream extraction operator function for the Fraction class:

#include <iostream>
#include <sstream>

class Fraction {
    private:
        int numerator;
        int denominator;
    public:
        Fraction(int num, int denom) : numerator(num), denominator(denom) { }
        friend std::istream& operator>>(std::istream& is, Fraction& frac);
};

std::istream& operator>>(std::istream& is, Fraction& frac) {
    std::string input;
    is >> input;
    std::stringstream ss(input);
    int num, denom;
    char slash;
    ss >> num >> slash >> denom;
    frac.numerator = num;
    frac.denominator = denom;
    return is;
}

You can use these overloaded operators to output and input Fraction objects as follows:

int main() {
    Fraction f1(3, 4);
    std::cout << f1 << std::endl; // outputs "3/4"
    
    Fraction f2(0, 1);
    std::cin >> f2; // inputs a Fraction from standard input in the form "num/denom"
    std::cout << f2 << std::endl; // outputs the input Fraction
    
    return 0;
}

I hope this helps! Let me know if you have any other questions.
