Unit6-07: Parsing Strings (Optional)

Learning Outcome

At the end of this lesson, you will be able to:

a string is just an array of characters
sometimes it is useful to split a sentence read from the user into a list of words.
in Python:
- you can read a string directly into a list of strings / words
in C++:
- you need to iterate over each character in a string and check if there is a space.
  - use aString.length()
  - build each word and push it onto the list of strings / words
  - if there is a space, start a new word
  - see the code using iterators below:
    - we will not use iterators. Just treat the string as an array of characters and iterator over it with a loop.

Create a program called “String Parser” that asks the user to enter a sentence. The program will then call a function that accepts the user's sentence as a string and returns a list of the words in the sentence. The words will then get displayed, one per line without any spaces.

Ensure the main() function catches any "bad" user input so that only "valid" input is passed to the function.

Note: The top-down design should be for the entire program. There should be a flowchart for each function.
