If/else if is driving me nuts.

I've been trying solve this problem for some time. I've also looked into other members' discussions with no result.

Program.cs
using System;

class Program
{

    static string CheckSpeed(double speed)

    {

        if (speed > 65)
            return string ("too fast"); 
    }

    {
        else if (speed < 45)
            return string ("too slow");
    }

    {
        else ("speed OK");
    }


    static void Main(string[] args)
    {

        Console.WriteLine(CheckSpeed(44));

        Console.WriteLine(CheckSpeed(88));

        Console.WriteLine(CheckSpeed(55));
    }

}

You have the right idea, but a few syntax issues:

  • the function body should be just one block of code between braces
  • braces around conditional code blocks begin after the conditional expression
  • braces around conditional code blocks are optional if the block has just one statement
  • "string" is not a function, and literals don't need type declarations
  • there is a "return" missing between the final else and the string
  • strings don't need to be enclosed in parentheses
    static string CheckSpeed(double speed)
    {
        if (speed > 65)
            return "too fast"; 
        else if (speed < 45)
            return "too slow";
        else
            return "speed OK";
    }
