How do I turn the tone/sound off using the slide switch?

Hey guys, I'm working on a project but I'm having difficulty with turning the sound off by using the slide switch. I'm a complete beginner.
I know I need to start it off as: pinMode(A0, INPUT_PULLUP);
And I need to use an if/else.

But just how would I write it?
Thanks!

What sound are you trying to turn off? On what device? It is unclear what you are talking about.

Oh sorry! I'm using the Circuit Playground and I'm trying to turn off the tone: tone(A0, 250)

noTone(pin) will turn a tone off, so in your case.. noTone(A0);

Not sure what you mean with "slideswitch", and why you use pinMode(A0, INPUT_PULLUP); or the analogue input pins for tone()
Post your code if you want help with that.
Read the forum rules first.
