So what do I have to Change in line 20?
I just cant find an answer on the web
using System;
class Program
{
static string CheckSpeed(double speed)
{
if(speed > 65)
{
Console.WriteLine("too fast");
}
else if(speed < 45)
{
Console.WriteLine("too slow");
}
else
{
Console.WriteLine("speed OK");
}
return speed;
}
static void Main(string[] args)
{
// This should print "too slow".
Console.WriteLine(CheckSpeed(44));
// This should print "too fast".
Console.WriteLine(CheckSpeed(88));
// This should print "speed OK".
Console.WriteLine(CheckSpeed(55));
}
}

with return
. Then your code paths will be returning .a value

Sometimes reading is just the answer thank You @KRIS NIKOLAISEN

4,042 PointsIf it wouldn´t be a challenge, I could also change from "static string" to "static double", right?

4,042 PointsHey thanks KRIS, but when I delete it, I get this message:
Program.cs(6,19): error CS0161: 'Program.CheckSpeed(double)': not all code paths return a value [/workdir/workspace.csproj]
The build failed. Please fix the build errors and run again.
Im a bit confused Right so not just my Code on line 20 is wrong.. but also the rest?
