/*
Which function:
	Equivalent to the function "toupper" in ctype.h.
Definition:
	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.
Return values:
	If the argument is a lower-case letter, the toupper() function returns
	the corresponding upper-case letter if there is one; otherwise, the argu-
	ment is returned unchanged.
