Practical Notes, Week 9: String Processing
============================================================================

The purpose of this practical is to have you work with string processing.

You will not be graded for this practical.

----------
Your Tasks
----------

1. Write a function substringBetweenChars, which has the following
   prototype:

   char* substringBetweenChars 
   (char* s, const char* ct, char a, char b)

   Given a string ct, this function copies into s the substring in ct
   whose first character is the leftmost occurrence of a in ct and
   whose last character is the rightmost occurrence of b in ct. It
   also returns a pointer to s.

   Example calls:

   substringBetweenChars(s, "hello", 'h', 'o') -> "hello"
   substringBetweenChars(s, "hello", 'e', 'l') -> "ell"
   substringBetweenChars(s, "hello", 'h', 'a') -> ""
   substringBetweenChars(s, "hello", 'a', 'o') -> ""
   substringBetweenChars(s, "hello", 'i', 'j') -> ""

2. Write a function endsWith, which has the following prototype:

   int endsWith(const char* cs, const char* ct)

   Given a string cs, this function returns true (non-zero) if cs ends
   with ct, false (zero) otherwise.

   Example calls:

   endsWith("hello", "lo") -> true
   endsWith("hello", "he") -> false
