Write the methods to implement the C class FullFraction disc

Write the methods to implement the C++ class FullFraction, discussed in class and outlined here. Test your implementation with the assign_FullFraction() code below.(No header file,all code in one file)

Maintain fractions internally in lowest terms - the best place to do this is in setFraction()

Be sure to maintain the sign of the fraction correctly

Avoid a 0 in the denominator by forcing the fraction to 0

Enhance toString() to display a mixed fraction (whole numbers and fraction) when the numerator is greater than the denominator

The output of the test driver is:

Solution

Hi, I have implemented functionality.

Please let me know in case of any issue.

#include <iostream>
using namespace std;

class FullFraction{

int numerator;
int denominator;
int gcd(int x, int y);
public:
FullFraction();
FullFraction(int n, int d);
FullFraction add(FullFraction rop);
FullFraction subtract(FullFraction rop);
FullFraction multiply(FullFraction rop);
FullFraction divide(FullFraction rop);
int getNumerator() const;
void setFullFraction(int numerator, int denominator);
int getDenominator() const;
float getDecimal() const;
std::string toString();
};
int FullFraction::gcd(int x, int y)
{
if (x <= 1 || y <= 1)
return 1;
while (x != y)
{
if (x > y)
{
if (0 == (x = x % y))
return y;
} else
{
if (0 == (y = y % x))
return x;
}
}
return x;
}
