Well, none of them is offered here.
For example.Code:char c = getchar(); if (is_digit(c)) { c -= '0'; // Do whatever }

But the original poster, remember? Used a switch/case for a menu. And the above solution breaks in case of UTF16 or Unicode characters. I though you were on about a universal "bullet proof" input method for numbers. But in this case we don't need numbers, so why bother?

I suppose the OP was, yes. So in the OP's code, it would work fine, your example. For a generic solution of getting the actual number it represents (the -48 discussion), my example is better.
And neither handles UTF properly.

Yes, but IMO the -48 explains better what is going on, even though it is not a good practice to follow in code for an actual program.
But what is the point of improving upon scanf's deficit, if there are still holes in the method.
I would argue that - '0' explains it even better (how can you subtract two letters from each other?).
To the last, then what is the point of using any method at all? Nothing is perfect. Remember that well. But there are ways to make it more perfect.

Wouldn't it be possible to make a univeral input method that recognices and handles any character encoding properly? I would think so, but I bet it's not going to be elegant. ;-)
Possible? No doubt. But messy, yes.
C++ handles these things much more smoothly.
