Feature: Strings Exercises for Basic Data Types

[KevinMulhern]

Description

After the student has gone through the Basic Data Types Lesson it would be good for them to practice what they have learnt by completing a few exercises.

Acceptance Criteria

The following exercises should be created for strings:

• An exercise for sub strings
• An exercise that uses some escape characters - the newline escape character is the most practical
• An exercise for capitalising the given string
• An exercise for upper casing the given string
• An exercise for down casing the given string
• An exercise for checking if a given string is empty
• An exercise for checking the length of a given string
• An exercise for reversing a string
• An exercise for stripping a given string of white space.

Additional Notes

These exercises should go in the existing string_exercises file.

We have an example exercise and test which demonstrates the pattern that should be followed for the strings exercises.

Working on this. I have most of it done, just missing the escape characters exercise.
