‘Whiling’ Away the Loops

In previous postings, I addressed ‘for’ loops. In today’s post, I want to demo ‘while’ loops. In ‘for’ loops, you loop over code for a specified period of time. In ‘while’ loops, you loop over code as long as a condition is true.  The steps of a ‘while’ loop are…

  1. Test condition
  2. Perform action if test returns true
  3. Repeat step one (1)

Here is the syntax for a ‘while’ loop…

Note: Make certain you affect the test condition within the ‘while’ loop. Otherwise, you will create an infinite loop.

Happy Coding!
