String Solutions

#3. Write a method #capitalize that accepts a string as an argument and capitalizes the first letter of the string. Note: Do not use the built in method String#capitalize

  def capitalize(string)
    first_letter = string[0]
    end_of_string = string[1..-1]

    first_letter.upcase + end_of_string
  end

#4. Write a method, #shout_then_whisper that takes in two strings, and shouts the first part, then whispers the second part. The output should look like this:

  shout_then_whisper("Hello", "McDouglas") == "HELLO!! ... mcdouglas"

  def shout_then_whisper(string1, string2)
    shout = string1.upcase
    whisper = string2.downcase

    "#{shout}!! ... #{whisper}"
  end

#5. Write a method, #how_long? that accepts a string as an argument. Your method should return a new string in the format:

  how_long?("I am a sentence :)") == "Your string is 18 characters long"

  def how_long?(string)
    character_count = string.length
    "Your string is #{character_count} characters long"
  end

#6. Write a method, #hyphenify that accepts a string as an argument. Your method should remove all the spaces and replace them with hyphens.

  def hyphenify(string)
    string.gsub(" ", "-")
  end
