> No, when you input a character, it is returned. Characters happen to be
> a subrange of integers in C. So if you input '2', what getchar() (or
> getche() on your platform) returns is '2'. But when you printf() this
> with "%d" you get to see that character's integer value, which on your
> encoding happens to be 50. I assume that if you typed 'A' you would get
> to see 65.
> Simply change "%d" in your printf() call to "%c" to make printf() print
> the actual character glyph.
