程序每执行一次循环体，循环条件中涉及到的变量就会发生改变，正在步步逼近满足跳出循环体的条件。

程序中最忌“死循环”。所谓的“死循环”就是指该循环条件永远成立，没有跳出循环体的机会。

请看我们用WHILE循环实现1到100累加为例，做一下说明：

“1+2+……+100”

部分程序如下：

sum = 0

i =1

WHILE 　i <= 100

sum = sum+ i

i=i+1

WEND

这段程序中，循环的条件是“i <= 100”；因此，一开始i肯定需要一个确定的值。前面的

　“i = 0”这一个语句，在声明变量i的同时，也为i赋了初始值“1”。这样，条件 i <= 100 得以成立(因为i为1，所以 条件“i <= 100” 当然成立)。

3．学习了循环语句的两种格式，我们来挖掘一下应用循环语句编写程序的“条件三要素”。

2．条件语句的主要功能是来实现算法中的条件结构。

因为人们对计算机运算的要求不仅仅是一些简单的代数运算，而是经常需要计算机按照条件进行分析、比较、判断，并且按照判断后的不同情况进行不同的操作和处理。如果是要解决像“判断一个数的正负”、“比较数之间的大小”，“对一组数进行排序”、“求分段函数的函数值”等很多问题，计算机就需要用到条件语句。
