Simple program, need help

File attached.

I need some help with a simple program to capitalize the first letter of
each word in a sentence.

I’m not sure if I should be using class Array, but I dont think that’s
the problem.

Here’s the code:

class Array
def title_format (title)
puts title.split(" “).each{|element| print
element.capitalize!}.join(” ")
return title_format
end
end

puts “Please type the sentence you want to have put in “Title Format””

title = gets.chomp

title.title_format

Help would be greatly appreciated. This is the error i get:

sentence_caps.rb:18: undefined method `title_format’ for “please help me
with my program”:String (NoMethodError)

Thanks

Which is exactly right – ‘title’ is a string and there’s no such
method.
But you can add one:

class String
def title_format
self.split.each{|element| element.capitalize! }.join(" ")
end
end

puts “what the heck”.title_format #=> What The Heck

You definitely don’t want the print and puts inside your method,
and in your example you’re trying to return the method itself, which
is bound to end badly :slight_smile:

HTH,

Thanks, greatly appreciated

What Hassan said, but something to consider is that this will change
your
string in ways you don’t necessarily want.

class String
def title_format
self.split.each{|element| element.capitalize! }.join(" ")
end
end

string = “unexpected\n \tWhitespace”
string.title_format # => “Unexpected Whitespace”

instead, I’d do it like this, which substitutes each run of

non-whitespace
characters

and substitutes them with their capitalized version

class String
def title_format
gsub(/\S+/) { |word| word.capitalize }
# which can actually be shortened to: gsub(/\S+/, &:capitalize)
end
end
string.title_format # => “Unexpected\n \tWhitespace”

Excellent point, thanks for that caveat.

Sheesh, old web guys – so cavalier about white space :slight_smile:

‘some string here’.gsub(/\b\w/){$&.upcase}

title.gsub(/\b\w/){$&.upcase}
