C offers a selection statement in several ways as if the program becomes less readable when the number of conditions increases. C has a multi-way selection statement calledthe switch statementthat is easy to understand to resolve this problem. The switch declaration is easy to understand if more...
6.8 控制流语句(Control Flow Statement) 程序最小的独立单元是语句(statement),语句一般由分号结尾,缺省情况下,语句是顺序执行的,但是当涉及逻辑判断控制时,就要求有控制流程序语句。控制流程序语句分为条件语句和循环语句,在C语言中,条件语句有if、if-else、switch等,而循环过程则由while、do-while和for语句支持。...
This chapter covers the following control flow statements:if statement [ES1] switch statement [ES3] while loop [ES1] do-while loop [ES3] for loop [ES1] for-of loop [ES6] for-await-of loop [ES2018] for-in loop [ES1] ...

The break statement ends execution of an entire control flow statement immediately. The break statement can be used inside a switch or loop statement when you want to terminate the execution of the switch or loop statement earlier than would otherwise be the case. ...
We can also use the break statement inside a for-loop to break it out abruptly. For example: v <- c(1:5) for (i in v) { if(i == 3){ break } print(i) } Output:[1] 1 [1] 2 Loop-control Statements Loop-control statements are part of control statements in R programming...
Swift提供了所有c类语言的控制流结构。包括for和while循环来执行一个任务多次;if和switch语句来执行确定的条件下不同的分支的代码;break和continue关键字能将运行流程转到你代码的另一个点上。 除了C语言传统的for-condition-increment循环,Swift加入了for-in循环,能更加容易的遍历arrays, dictionaries, ranges, strings...
In this chapter, we will learn about various flow control statements. What are the Flow Control Statements? A Flow Control Statement defines the flow of the execution of the Program. There are 7 different types of flow control statements available in Python: if-else Nested if-else for while ...
本篇推文是学堂君学习第5章“Control flow”的笔记,原文链接是adv-r.hadley.nz/control,可在文末“阅读原文”处直达。控制流(control flow)语句分为两种:分支结构和循环结构。前者典型的是if条件语句,后者典型的是for循环。 5.1 Introduction 5.2 Choices 5.2.2 Vectorised if 5.2.3 switch statement 5.3 Loops...
