601 PointsConfused on why this isn't working, what am I missing?
I'm confused on what I need to return because the console keeps saying that it can't convert double to string
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));
}
}

return "to fast"; return "to slow"; return "speed OK;
