本文探讨了程序设计中的核心概念：布尔表达式、分支机制（包括if-else及switch-case）以及循环结构（涉及while、do-while和for）。特别提到了整数值在布尔上下文中的使用方式，0被视为false，非0值则为true。同时对比了不同类型的循环语句，并介绍了逗号运算符的作用。

The main topics of the chapter2 are BOOLEAN EXPRESSION,BRANCHING MECHANISMS and LOOPS.

There is a point which would be worth to notice,the point is int value can be used as boolean.The 0would be recognised as false,the others would be recognised as true.

Branching mechanisms have two kinds of method,if--else and switch--case.

The thirdpart introduces while,do--while and for statements.In this part,the author also introduce the comma operator,which use to get the last value to itself.The difference between while and do--while is the do--while statement will run one time at least,the while not.They have the same result in the other environment.
