Changing format type.

Hello again me and again a problem
I'm using a graphic lcd and keypad.
I want to show the button which is pushed.
There is

Let's say your int (we'll call it 'result') is what you pull in from the keypad.

Since it's a 4x4 keypad (I'm making this up) you've wired up 'result' to equal a range of 0-15

If you want to PRINT 0 to 15, you want to convert that to ascii.

The easiest way is to simply do this:

printf("%u", result);

This will print result (which is an unsigned int) anywhere from 0-15.

If you want padded preceding 0's,
printf("%02u", result);

This will print 00-15 (because of the 2).

And that's it.

Easy.

PrintF -- it's your friend.
