Get number of occurrences of one string in another

[dunbarx at aol.com]

Bob's is the cutest of all solutions. Odd, but cute.


But this is a perfect chance to use a simple array:


repeat for each char tChar in yourString
  add 1 to countYourChar[tChar]
end repeat


And then get the count from the array.

I am everyone's Uncle. Still, no repeat loops needed. See my solution.
