Example 2: Writing Loop with Multiple if-ConditionsIt is also possible to include several if (or else) conditions inside of a loop. Have a look at the following example code:for(i in 1:5) { # Head of for-loop if(i < 4) { # First if-condition if(i %in% seq(2, 10, 2)) {...
结果1 题目 最基本的While循环由循环框架(Loop Frame)、重复端口(Loop Iteration)以及条件端口(Loop Condition)组成。与For循环类似,While循环执行的是包含在循环框架中的程序,但执行的___却不顾定,只有当满足给定的条件时,才停止循环的执行。 相关知识点: 试题来源: 解析 循环次数 反馈 收藏 ...
The do...while loop is a variant of the while loop with one important difference: the body of do...while loop is executed once before the condition is checked. Its syntax is: do { // body of loop; } while (condition); Here, The body of the loop is executed at first. Then the...
A while loop in C++ consists of three main parts, as specified below:The Test ExpressionThe Test Expression is a condition that decides whether the body of the loop will be executed or not. The result of this is always a boolean statement that is true or false. The loop execution process...
跳转语句之ITERATE语句 ITERATE语句:只能用在循环语句(LOOP、REPEAT和WHILE语句)内,表示重新开始循环,将执行顺序转到语句段开头处。如果你有面向过程的编程语言的使用经验,你可以把 ITERATE 理解为 continue,意思为 再次循环。 语句基本格式如下: ITERATE label...
Do While...Loop 是 Visual Basic (VB) 中一种常见的循环结构,允许你在循环开始时检查条件。如果条件为真,则执行循环体;如果条件为假,则跳过循环体。 语法 changchun.b2b.fxcn.info Do While condition ' 循环体 Loop 解释 condition:这是一个布尔表达式,在每次循环开始时检查。如果条件为真,则执行循环体;如...
Do While condition ' 循环体 Loop 在这种形式中,条件在每次循环开始时检查。如果条件为假,则不会执行循环体。 2. 条件在循环结束时检查 vb Do ' 循环体 Loop While condition 在这种形式中,循环体至少执行一次,因为条件在循环结束时检查。 3. 使用 Until 关键字 ...
With the potential for high repetition, while loops can be performance bottlenecks if not used judiciously. Optimization strategies involve minimizing the work inside the loop and making use of efficient algorithms and data structures to guarantee that the condition is met in the shortest possible iter...
