Hello I need help with my C++ program for part 2

- include the Special ++/-- Test Pattern as part of your final test program

- Provide the reason/explanation on why the increment/decrement test sequence (one statement vs 6 statements) produce different outcome.

Code:

#pragma once #ifndef FRAC_H #define FRAC_H #include #include

using namespace std;

class Frac;

ostream& operator > (istream& strm, Frac&);

class Frac { private: int num; int den; int gcd(int a, int b) { int max, min; a = abs(a); b = abs(b);

if (a

while (max % min != 0) { int tmp = max % min; max = min; min = tmp; }

return(min); } void lowTerms(int& num, int& den);

public: Frac() { num = 0; den = 1; }

Frac(int n) { num = n; den = 1; }

Frac(int n, int d) { num = n / gcd(n, d); den = d / gcd(n, d); }

Frac(string s);

Frac(const Frac& rhs) { num = rhs.num; den = rhs.den; }

Frac operator=(const Frac& rhs) { num = rhs.num; den = rhs.den; }

void setNum(int n) { num = n; } void setDen(int d) { den = d; }

int getNum() const { return num; } int getDen() const { return den; }

Frac operator + (const Frac& rhs); Frac operator - (const Frac& rhs); Frac operator * (const Frac& rhs); Frac operator / (const Frac& rhs);

Frac operator++(); Frac operator++(int); Frac operator--(); Frac operator--(int);

bool operator == (const Frac& f2); bool operator != (const Frac& f2); bool operator (const Frac& f2); bool operator = (const Frac& f2);

operator int() { return (num) / den; } operator float() { float temp; temp = static_cast(num) / static_cast(den); return temp; } friend ostream& operator > (istream& strm, Frac& f);

};

void Frac::lowTerms(int& num, int& den) { int div = gcd(num, den); num = num / div; den = den / div; }

Frac::Frac(string s) { stringstream ss(s); ss >> num; char peekchar = ss.peek(); if (ss && peekchar == '/') { ss.get(); ss >> den; } }

Frac Frac::operator++() { num += den; lowTerms(num, den); return *this; }

Frac Frac::operator++(int) { num += den; lowTerms(num, den); return *this; }

Frac Frac::operator--() { num -= den; lowTerms(num, den); return *this; }

Frac Frac::operator--(int) { num -= den; lowTerms(num, den); return *this; }

bool Frac::operator == (const Frac& f2) { bool status; if (num == f2.num && den == f2.den) { status = true; } else { status = false; } return status; }

bool Frac::operator != (const Frac& f2) { bool status; if (num != f2.num || den != f2.den) { status = true; } else { status = false; } return status; }

bool Frac::operator

bool Frac::operator > (const Frac& f2) { bool status; if (num > f2.num&& den > f2.den) { status = true; } else { status = false; } return status; }

ostream& operator

istream& operator >> (istream& strm, Frac& rhs) { char c; strm >> rhs.num; strm >> c; strm >> rhs.den; rhs.lowTerms(rhs.num, rhs.den); return strm; }
