Looping In Objective-C

Last week we wrapped up our look at the different ways to construct loops in Objective-C. Here's a quick overview of the posts.

There are four looping statements in Objective-C:

• the for loop
• the for...in loop
• the while loop
• the do...while loop

The for loop is the most flexible; we looked at some for loop idioms.

We examined the two loop flow modifiers:

• break
• continue

Finally we wrapped up with a look at goto and examined common uses of goto.

Today, we start a new topic: variables.
