Use C++

Modify the code to have operator overloading functions with the following operators.
==, <, <=, >, >=, +, -, *, /
Use the Rational interface and main code in the next page.

I need three files one main.cpp, one rational.cpp file and one rational.h file. Main file and h file are shown on the picture they don't need to be changed I just need rational.cpp file.

Here is the rational.cpp file I have:

#include "rational.h"
Rational::Rational()
{
numerator = 0;
denominator = 1;
}

Rational::Rational(int num, int den)
{
numerator = num;
denominator = den;
}

istream& operator >>(istream& take, Rational& r1)
{
string userInput = " ";
string num = " ";
string den = " ";
bool findSlash = false;
take >> userInput;
for (int i = 0; i < userInput.length(); i++)
{
if (userInput[i] != '/' && !findSlash)
{
num = num + userInput[i];
}
else if (userInput[i] == '/')
{
findSlash = true;
}
else if (userInput[i] != '/' && !findSlash)
{
den = den + userInput[i];
}
}
r1.numerator = stoi(num);
r1.denominator = stoi(den);
return take;

}

ostream& operator<<(ostream& out, const Rational& r1)
{
Rational temp(r1.numerator, r1.denominator);
temp.simplify();
out << temp.numerator << "/" << temp.denominator;
return out;

}

Rational operator+(const Rational&f, const Rational&r)
{
Rational temp((f.numerator * r.denominator + r.numerator * f.denominator), (f.denominator * r.denominator));
return temp;
}

Rational operator-(const Rational&f, const Rational&r)
{
Rational temp((f.numerator * r.denominator - f.denominator * r.numerator), (f.denominator * r.denominator));
return temp;
}

Rational operator*(const Rational&f, const Rational&r)
{
Rational temp((f.numerator * r.numerator), (f.denominator * r.denominator));
return temp;
}

Rational operator/(const Rational&f, const Rational&r)
{
Rational temp((f.numerator * r.denominator), (f.denominator * r.numerator));
return temp;
}

bool operator==(const Rational& f, const Rational& r)
{

}

bool operator>(const Rational&, const Rational&)
{

}

bool operator<(const Rational&, const Rational&)
{

}

bool operator>=(const Rational&, const Rational&)
{

}

bool operator<=(const Rational&, const Rational&)

Enter the first fraction (eg 3/4): 3/5
Enter the second fraction (e. g. 3/4): 2/6
