curious about switches

At end of my prog I want a line that says "Do Again.....(Y/N)......"
I am thinking that a switch afterwards is the way to do this. Now I am trying to figure out how to make the switch (when Y or y is entered) return to the beginning of the prog and rerun the whole thing.

I am pretty much stumped...if anyone can help thanks in advance...

Basically you will need some code in the form -

again = true;
while (again)
{
// do code

// ask question

// if 'y' again = true

// if 'n' again = false
}

Hope this helps,

Hey thanks for the response KM

lol I had decided to chunk the switch and go for a do/while instead. Glad to see you suggested it also, makes me think I am on the right track.

Think I almost got it now :
