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...
conditional control statement的意思是“条件控制语句”。在计算机编程中，条件控制语句用于根据特定的条件来控制程序的执行流程。以下是关于条件控制语句的一些关键点：定义：条件控制语句是一种编程结构，它允许程序根据一个或多个条件的真假来决定执行哪一段代码。作用：通过条件控制语句，程序可以实现分支逻辑...
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。...

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...
