toupper() or tolower()

Line 8, 12: '122', etc are not valid character literals. You're confusing the decimal value with a character literal. character literals (enclosed in single quotes) must be a single character. i.e. 'z' To compare the decimal value, just use the decimal number.

if (a <= 122 && a >= 90)

Charater literals are clearer in this situation:

if (a <= 'z' && a >= 'Z')

Note that the above test will cause some graphics characters (91-96) to be shifted.


PLEASE USE CODE TAGS (the <> formatting button) when posting code.
It makes it easier to read your code and also easier to respond to your post.
