Even though while and do/while statements are quite powerful, some tasks are so common in writing software that special types of loops were created—for example, iterating over a statement exactly 10 times or iterating over a list of names. You could easily accomplish these tasks with various while loops that you've seen so far, but they usually require a lot of boilerplate code. Wouldn't it be great if there was a looping structure that could do the same thing in a single line of code?

With that, we present the most convenient repetition control structure, for loops. There are two types of for loops, although both use the same for keyword. The first is referred to as the basic for loop, and the second is often called the enhanced for loop. For clarity, we refer to them as the for loop and the for-each loop, respectively, throughout the book.
