/* The toupper() function converts a lower-case letter to the corresponding
	upper-case letter.  The argument must be representable as an unsigned char
	or the value of EOF.
	
	If the argument is a lower-case letter, the toupper() function returns the
	corresponding upper-case letter if there is one; otherwise, the argument is
	returned unchanged. */
