Question

C++ adding fractions

Main:

FRACTION.CPP :

FRACTION.H :

input file contains:

30 / 70 + 4 / 5

10 / 30 - 2 / 7

20 / 10 * 5 / 3

40 / 90 / 1 / 9

4 / 5 = 4 / 5

4 / 4 = -1 / -1

2 / 3 = 3 / 2

Output should look like:

30/70 + 4/5 = 43/35

10/30 - 2/7 = 1/21

20/10 * 5/3 = 10/3

40/90 / 1/9 = 4/1

4/5 = 4/5 = True

4/4 = -1/-1 = True

2/3 = 3/2 = False

ALSO, need a default constructor to set numerator & denominator to zero

- input >> frac.numerator; // reads one integer out of the stream

#include #include #include #include "Fraction . h" iostream> using namespace std int mainO f // Input/output files ifstream fin("input.txt"); ofstream fout("output.txt"); // Throw error if can't open input file if(!fin) cerr

Explanation / Answer

//Fraction.h
#include <iostream>
using namespace std;

class Fraction
{
//Add the variables and functions you need to. getGCD and reduce
//are provided for you
public:
int numerator,denominator;
private:
   int getGCD(int num1,int num2);
public:
   void reduce();
   Fraction()
   {
       numerator=0;
       denominator=0;
   }
};

//Fraction cpp

#include "Fraction.h"
#include <iostream>
#include <string.h>

using namespace std;

int Fraction::getGCD(int num1,int num2)
{
   int remainder=num2%num1;
   if(remainder!=0)
   return getGCD(remainder,num1);
return num1;
}

void Fraction::reduce()
{
   int gcd=getGCD(numerator,denominator);
   numerator/=gcd;
   denominator/=gcd;
}

//main cpp

#include "Fraction.h"
#include <iostream>
#include <fstream>

using namespace std;

int main()
{
   ifstream fin("input.txt");
   ofstream fout("output.txt");
  
   if(!fin)
   {
       cerr<<"Error opening input file";
       //system("pause"");
   }
   while(fin.good())
   {
       Fraction fract1,fract2;
      
       char oper;
       fin>>fract1.numerator>>oper>>fract2.numerator;//calling class members via object
      
       fout<<fract1.numerator<<" "<<oper<<" "<<fract2.numerator<<"="; //calling class members via object
       switch(oper)
       {
           case '+':
                       fout<<fract1.numerator+fract2.numberator<<endl;
                       break;
           case '-':
                       fout<<fract1.numberator-fract2.numerator<<endl;
                       break;
           case '*':
                       fout<<fract1.numberator-fract2.numerator<<endl;
                       stdout<<fract1<<*fract<<<<endl;
                       break;
           case '/':
                       fout<<fract1/fract2<<endl;
                       break;
           case '=':
                   if(fract1==fract2)
                   fout<<"True"<<endl;
                   else
                   fout<<"False"<<endl;
                   break;
                  
       }
   }
   fin.close();
   fout.close();
   return 0;
}
