Question
in C# i need to
Add an operator*() method to the Fraction class created in Programming Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2.
my errors are in the pictures
my code is
public class Fraction
{
private int numerator;
private int denominator;
public Fraction(int num, int denom)
{
numerator = num;
denominator = denom;
}
// Define the * operator for Fraction objects
public static Fraction operator *(Fraction a, Fraction b)
{
int num = a.numerator * b.numerator;
int denom = a.denominator * b.denominator;
return new Fraction(num, denom).Reduce();
}
// Reduce the fraction to its lowest terms
public Fraction Reduce()
{
int gcd = GCD(numerator, denominator);
numerator /= gcd;
denominator /= gcd;
return this;
}
// Calculate the greatest common divisor
private int GCD(int a, int b)
{
if (b == 0)
return a;
return GCD(b, a % b);
}
}
class FractionDemo2
{
static void Main()
{
// Create two Fractions
Fraction a = new Fraction(2, 3);
Fraction b = new Fraction(3, 4);
// Multiply the two Fractions
Fraction result = a * b;
// Display the result
Console.WriteLine("{0} * {1} = {2}", a, b, result);
}
}
