Hi, if we want to have user’s answer all uppercase, why this works
Console.Write("YES or NO: ");
string noiseChoice = Console.ReadLine();
and this does not
Console.Write("YES or NO: ");
string noiseChoice.ToUpper() = Console.ReadLine();
You are saying change noiseChange to upper case before you’ve even stored any value in it. How does that make sense?
Aside, you can only really assign/change variables on the right hand side of the = sign.
I can see where you have gone wrong, try this:
Console.Write("YES or NO: ");
string noiseChoice = Console.ReadLine();
noiseChoice = noiseChoice.ToUpper();
When ever you use noiseChoice after that it will be in captials.
so you could print it to the console like so
Console.Write("YES or NO: ");
string noiseChoice = Console.ReadLine();
noiseChoice= noiseChoice.ToUpper();
Console.WriteLine(noiseChoice);
