Chapter 3 - Control Flow 控制流

The control-flow of a language specify the order in which computations are performed. We have already met the most common control-flow constructions in earlier examples; here we will complete the set, and be more precise about the ones discussed before.

程序设计语言中的控制流语句用于控制各计算操作执行的次序。在前面的例子中，我们曾经使用了一些最常用的控制流结构。本章将更详细地讲述控制流语句。
