While loop in swift works in a way where it will first check for the test condition which is mostly a Boolean expression and then it will be evaluated whether true or false, suppose in case the evaluation comes out to be true then it will check for the statements inside the while loop ...
In this episode of Swift Fundamentals, you learn how to use a while loop in Swift and, more important, when it is appropriate to use a while loop over a for loop. Let's get started. What Is a While Loop? Like a for loop, a while loop is a control flow statement for repeatedly ...
In the above program, we imported a package Swift to use the print() function using the below statement,import Swift; Here, we created two integer variables cnt1 and cnt2, both are initialized with 1. Then we printed numbers on the console screen using the nested while loop....

Swift while 循环用于运行特定代码,直到满足特定条件。while 循环的语法为:while (condition){ // body of loop } 在这里,while 循环计算括号 () 内的条件。 如果条件求值为 true,则执行 while 循环中的代码。 再次判断条件。 该过程继续,直到条件为 false。 当条件求值为 false 时,循环停止。while...
while 只要给定条件为真,Swift 4 编程语言中的循环语句就会重复执行目标语句。 句法 的语法 while Swift 4 编程语言中的循环是 - while condition { statement(s) } 复制 这里statement(s)可以是单个语句或语句块。这condition可以是任何表达式。当条件为真时循环进行迭代。当条件变为假时,程序控制将传递到紧...
解决While loop问题 - Python 当你使用while循环时,你需要确保循环的终止条件最终会被满足,否则循环将会无限执行下去。通常情况下,你可以在循环内部修改循环控制变量,使得终止条件得以满足。 1、问题背景 一位开发者在使用Python开发一个基于文本的游戏时,遇到了 while 循环的问题。他将游戏代码和音频处理代码结合在一...

当迭代次数未知时, 将While和Repeat while循环用作for-in循环的替代方法。 while循环执行一组语句, 直到出现错误条件为止。当你不知道迭代次数时, 通常使用此循环。 Swift中有两种类型的循环: while循环 重复While循环 Swift的While循环 Swift while循环在每次传递开始时评估其条件。
