Question

In class need to define two fields:

1. Integer part of the number - ulong; & fractional part of the number - ushort in C#

Using C#, create the following methods:

1. Method for adding two prices (parameters for function is 2 numbers, integer(main currency) and fractional parts(Fractional currency))

2. Method for adding two prices(parameter is object of same type as your class)

3. Method for adding two prices(parameter is string)

Answer 1

Code:

using System;

class Amount
{
    private ulong integerPart;
    private ushort fractionPart;

    public Amount(ulong integerPart, ushort fractionPart)
    {
        this.integerPart = (ulong) integerPart + (ulong) fractionPart / 100;
        this.fractionPart = (ushort) (fractionPart % 100);
    }

    public void AddPrices(ulong integerPart, ushort fractionPart)
    {
        this.integerPart += (ulong) integerPart + (ulong) ((this.fractionPart + fractionPart) / 100);
        this.fractionPart = (ushort) ((this.fractionPart + fractionPart) % 100);
    }

    public void AddPrices(Amount c)
    {
        AddPrices(c.integerPart, c.fractionPart);
    }

    public void AddPrices(string s)
    {
        string[] money = s.Split('.');
        ulong integerPart = Convert.ToUInt64(money[0]);
        ushort fractionPart = Convert.ToUInt16(money[1]);

        AddPrices(new Amount(integerPart, fractionPart));
    }

    public override string ToString()
    {
        return $"Amount: ${this.integerPart}.{this.fractionPart}";
    }
}

class Program
{
    static void Main(string[] args)
    {
        // Console.WriteLine("Hello World!");
        Amount a = new Amount(20, 98);
        Amount b = new Amount(23, 88);

        Console.WriteLine(a.ToString());
        a.AddPrices(20, 50);
        Console.WriteLine(a.ToString());
        a.AddPrices(b);
        Console.WriteLine(a.ToString());
        a.AddPrices("10.87");
        Console.WriteLine(a.ToString());

    }
}
