一、有了 for 循环,还要 while (1)的原因. 尽管for循环在大多数情况下能够满足循环的需求,但在特定情况下,使用while (1)(或while (true))仍然具有一些优势和适用场景:. 1、无限循环. while (1)是一种无限循环结构,循环条件恒为真,可以用于需要持续执行某段代码 ...

while(i)和while(! i)的意思要看i这个变量( 表达式 )的值是真还是假(0和NULL就是假)。 while(1)和while(99)和while(-76)甚至while(3-100)这类只要括号中的值(或表达式的值)非0,意思一样,代表可以循环并执行循环体,如果是while(0),则代表不执行循环并跳过循环体。

The difference is that the while loop will continue to execute as long as the condition is true. In other words, instead of executing if something is true, it executes while that thing is true. 再来一个例子来说明这个问题:. count = 0. if count < 9: print"Hello, I am an if statement and count is", count. while count <= 9: print ...

首先这3个词在引导时间状语从句时,如果从句的谓语动词是可以持续的,那么3个词是可以互换的。. 比如:When/While/As he walked along the river, he heard a young boy calling"help". 不同之处:. 1. When还可以接瞬时动词,比如:When I arrived at the office, Jane and Paul were working at their ...

1、while循环. 如图所示,while循环在执行之前,会先判断条件的对错,如果条件对,才执行循环,如果条件错,则循环跳过,直接进入下一步。. 因此题主所述:“如何在while判定为false结束循环后,再开始运行下一个循环?. 如果while 判定为False后,该循环会被 ...

while 循环: 只要特定的条件为真,就会重复执行循环体。 当条件不为真时,循环退出,继续执行后面的语句。 总的来说,如果要在特定的条件下执行一次或多次循环,可以使用if 循环或 while 循环。选择哪一种循环取决于特定的需求。

说明: 斐波那契数列(Fibonacci sequence),又称黄金分割数列,是意大利数学家莱昂纳多·斐波那契(Leonardoda Fibonacci) 在《计算之书》中提出一个在理想假设条件下兔子成长率的问题而引入的数列, 所以这个数列也被戏称为"兔子数列"。
