I have an assignment that I need your help with. This is on Ratio Data Type. Use C++ (Dev-C++ preferred so I can see the output). Part I was done last week so I will post the program here. The assignment now is to do Part II and Part III. Thanks in advance.

And here is the program for Part I incase, posted here.

#include using namespace std;

class Ratio

{

private:

//data members

int numerator;

int denominator;

// Recursive helper function to return gcd of a and b

int gcd(int a, int b)

{

// base case

if (a == b)

return a;

//if a is greater

if (a > b)

return gcd(a-b, b);

return gcd(a, b-a);

}

public:

//default constructor

Ratio()

{

numerator = 1;

denominator = 1;

}

//two argument constructor

Ratio(int num,int den)

{

if(num

numerator = 1;

if(den

denominator=1;

int g=gcd(num,den);

numerator=num/g;

denominator=den/g;

}

//mutator function

void setNumerator(int n)

{

if(n

numerator = 1;

else

{

int g = gcd(n,getDenominator());

numerator = n / g;

}

}

//mutator function

void setDenominator(int d)

{

if(d

denominator = 1;

else

{

int g = gcd(getNumerator(),d);

denominator = d / g;

}

}

//accessor gunction

int getNumerator()

{

return numerator;

}

//accessor function

int getDenominator()

{

return denominator;

}

//get double value

double getDoubleValue()

{

double value=(double)getNumerator()/getDenominator();

return value;

}

//helper function

void print()

{

cout

}

};

//main function to test the above class

int main()

{

Ratio r;//1st object

cout

r.print();

cout

Ratio ra(8,12);//2nd object

cout

ra.print();

cout

//taking user inputs

int num,den;

cout

cin>>num;

cout

cin>>den;

ra.setDenominator(den);//modifying 2nd object

ra.setNumerator(num);//modifying 2nd object

cout

ra.print();

cout

cout

return 0;

}

Part II: Utility Functions Create separate functions (outside of the class) to perform the following operations: void printRatio (Ratio r): Print a Ratio in the form a/b. Ratio getRatio ) Get input from the user for a numerator and denominator and return a Ratio with the values indicated by the user . Provide public functions that perform arithmetic on your new data type: Add, Subtract, Multiply, Divide two Ratios. The result of arithmetic operations should be a Ratio in reduced form. Review the rules of fractional arithmetic to make sure your functions work as one would expect them to. Remember that for addition and subtraction you need to find a common denominator, while that is not necessary for multiplication and division
