[Bluej-discuss] For Loop Doubt again....

[Bryan J. Higgs]

To say it as clearly as I can:

    * Both j++ and ++j are expressions that return values
    * Both expressions result in the value of j being incremented (this
      is known as a 'side-effect' of the expression)
    * The difference between the two expressions is that the
      (post-increment) expression j++ returns the original value of j
      (that is, the expression is evaluated before the increment
      occurs), while the pre-increment expression ++j returns the
      incremented value of j (that is, the expression is evaluated after
      the increment occurs)
    * If the value of the expression is ignored (as in your for loop
      example), then there is no observable difference between j++ and ++j.

I hope that helps.

Regards

Bryan
