Question

I am having trouble passing the return value from TheMethod() to Main and displaying the word if the if statement is passed as true.

I have thought of two ways of doing this, neither has worked but I think I am missing synatx.

1. Using a return ?; non void method and then displaying the returned value.
2. Using a void method and actually writing out(example below)

So yes I am new at this, however I have made so many iterations everything is blending together and I have forgot what I have tried. Any help on the syntax be great for either of these ways.

Basically I need it to iterate numbers

1,2,3,4 and depending on if the current iteration matches an expression in the if statements it will display a word.

Example:

if (3 = i)
{
   Console.WriteLine("Word");
}

Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Proj5
{
class Program
{
    int i = 0;



    static void Main(int i)
    {

        for (i = 0; i < 101; i++)
        {

            Console.WriteLine("test");
        }
    }

    string TheMethod(int i)
    {
        string f = "Word1";
        string b = "Word2";


        if (i == 3)
        {
            return f;
        }

        if (i == 5)
        {
            return b;
        }

        if (0 == (i % 3))
        {
            return f;
        }

        if (0 == i % 5)
        {
            return b;
        }
        else
        {
            return b;
        }

    }
}
}

Note: You don’t need if i == 5 and a separate one for i % 5 == 0. % is “mod” which means the remainder after the division, so 5 / 5 = 1, there is no remainder so 5 mod 5 = 0…

Here is a rough guide/fix for you attempt at FizzBuzz:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Proj5
{
class Program
{
    private static void Main()
    {
        for (int i = 0; i < 101; i++)
        {
            Console.WriteLine(TheMethod(i));
        }
    }

    string TheMethod(int i)
    {
        string f = "Fizz";
        string b = "Buzz";

        if ((i % 3 == 0) && (i % 5 == 0))
        {
            return f+b;
        }
        if (i % 3 == 0)
        {
            return f;
        }

        if (i % 5 == 0)
        {
            return b;
        }

        return i.ToString();

    }
}
}

However there are cleaner solutions:

string result = "";
for (int i = 1; i < = 101; ++i)
{
    if ((i % 3 == 0) && (i % 5 == 0)) result += "FizzBuzz";
    else if (i % 3 == 0) result += "Fizz";
    else if (i % 5 == 0) result += "Buzz";
    else result += i.ToString();
    result += ", ";
}

Or, if you prefer LINQ-y Lambas:

public static void FizzBuzz()
{
    Dictionary<Func<int, bool>, Func<int, string>> rules = new Dictionary<Func<int, bool>, Func<int, string>>();
    rules.Add(x => x % 5 == 0 && x % 3 == 0, x => “fizzbuzz”);
    rules.Add(x => x % 3 == 0, x => "fizz");
    rules.Add(x => x % 5 == 0, x => "buzz");
    rules.Add(x => x % 5 != 0 && x % 3 != 0, x => x.ToString());
    rules.Add(x => true, x => "\n");

    var output = from n in Enumerable.Range(1, 100)
                 from f in rules
                 where f.Key(n)
                 select f.Value(n);

    output.ToList().ForEach(x => Console.Write(x));
}
