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.

for 5/6:

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);
