TAKING STRINGS APART (cont.)

• Take a string as input.

• Return a vector<string> containing all the words.

• Strings support indexing.

• Suppose you had a string s of at least one character.

  • s[0] = the first character of s.
  • s[s.size( ) - 1] is the last character of s.

• We'll use two indices to point to the start of a word and the space following it.
