Subject: false || not(true)

Hi>Volks

This is my 1st post to this ML,
but…

I read 'bout a problem: (false || not(true))
in a place, and made a little considerations.

I give NOW, the source code AsIs,
with the 'comments' in it…
＝＝＝＝＝
#!/usr/bin/env ruby -Ku

def	case1(c)
	if c.nil?
	# does nothing
	elsif !c	# c == false || not true
	# does nothing
	else
		puts "case1: ", c
	end
# It's just NO problem, in C-programmer fashion [not fully tested]
end

def	 case2(c)
	if c.nil?
	# does nothing
# c == false || not true	if you want it to be TRUE, before that,
	#elsif c.class == Boolean or
	#elsif c.class != Char	or something, you must ask.
#	1st of all, have WE Classes like Boolean or Char ???
	elsif c.class != String	#	now this line may be wrong question…
	# does nothing
		puts "case2: c is no String"
	elsif !c
		puts "case2: ", c
	end
end

c = STDIN.getc()

case1(c)
case2(c)

# Was it just Me? that
# got troubled with needless TRUE
# in evaluating True-False, aString(or aChar) AsIs…
