Question

C++ I need help adding to this program. Here's my assignment:

(1) Add the following functions to your working mixed number class:

Overload the ==, <, and > comparison operators

Overload the + and * arithmetic operators

Overload the insertion (<<) operator: It should display whole part, space, numerator, forward

slash, denominator: 5 4/13

Overload the extraction (>>) operator: It should read integer, integer, character, integer. That is,

it can assume that the numerator, forward slash, and denominator are input any white space

between: 7 2/3

(2) Modify your main driver file so that it will test all of your functions completely. Using an operator

only one time in your driver isn't a sufficient test of that operator.

Here is my 3 Files so far

Main.cpp:

#include
#include "MixedNum.h"
using namespace std;

int main()
{
MixedNum n1(5,6,7), n2(3,15,9), n3(-6,9,8), n4(8,3,1),
n5(10, 6, 1), n6(4,3,1), n7(0,5,2);
n1.display();
n2.display();
n3.display ();
n4.display();
n5.display();
n6.display();
n7.display();

   return 0;
}

Implementation File:

#include
#include "MixedNum.h"
#include
using namespace std;

   MixedNum::MixedNum(){
       wholeNum= 0;
       numer= 0;
       denom=1;
       }
      
   MixedNum::MixedNum(int wNum,int num, int den){
       wholeNum=wNum;
       numer= num; denom = den;
       simplify();
      
   }
   void MixedNum::simplify()
{
    int gcd = GCD( numer , denom);
  
if (wholeNum < 0 || numer < 0 || denom <= 0 )
{
   cout<< "ERROR : invalid number"<< endl;
   wholeNum= 0;
           numer= 0;
           denom=1;
}
else
    wholeNum = numer/ denom + wholeNum;
    numer %= denom;
           numer /= gcd;
           denom /= gcd;
          


}

   void MixedNum::display()const {
       cout << "Number: " << wholeNum<<" "<< numer << "/"<< denom<   
   }
  
   int MixedNum::GCD(int numer, int denom){
       while (numer!= denom){
           if(numer > denom)
               numer = numer - denom;
           else
               denom= denom- numer;
       }
           return numer;
}

Header File:

   
   class MixedNum
   {
       private:
           int wholeNum;
           int numer, denom;
           void simplify();      
       public:
          MixedNum();
           MixedNum(int,int,int);
           void display() const;
           GCD(int , int );
   }
       ;
