如果条件为false,则循环将在此处结束。do while 因此,两者之间的区别在于,循环至少执行一次语句集。do while Syntax while(<condition>)begin// Multiple statementsenddobegin// Multiple statementsendwhile(<condition>); Example #1 - while loop moduletb;initialbeginintcnt =0;while(cnt <5)begin$display("cn...
If the test expression is evaluated totrue, codes inside the body of the loop are executed, and test expression is evaluated again. This process goes on until the test expression is evaluated tofalse. When the test expression is evaluated tofalse,do..whileloop terminates. Flowchart of do......
while loop do...while loop In the previous tutorial, we learned about for loop. In this tutorial, we will learn about while and do..while loop. while loop The syntax of the while loop is: while (testExpression) { // the body of the loop } How while loop works? The while loop ev...
do while 循环语句的含义 在编程中,循环结构是一种用于重复执行一段代码直到满足特定条件的控制流机制。do while 循环是其中一种常见的循环类型,它在许多编程语言中都得到了支持(尽管具体的语法可能有所不同)。下面是对 do while 循环的详细解释: 基本含义 do while 循环的基本思想是“至少执行一次代码块,然后检查...
C# LOOPS: WHILE VS DO-WHILE May 06, 2019 by Bradley Wells This tutorial will explain the difference between a While loop and a Do While loop in C#. You will learn when to use each type of iterative statement by working through practical examples. C# While Loop In previous tutorials, you...
下列关于 do while , loop 和 do, loop while 循环执行循环体次数的描述正确的是 ()。A. do while , loop 循环和 do, loop while 循环至少都执行一次 B. do while , loop 循环可能不执行, do, loop while 循环至少执行一次 C. do while , loop 循环至少执行一次, do, loop while 循环可能不执行 D...
Do While myNum > 10 counter = counter + 1 myNum = myNum - 1 Loop 循环体内执行的可执行语句也是可选的,通常情况下都会写。 示例,用循环的方法求大于0的整数的2进制数值(10进制转2进制) Sub Dec2Bin() '大于0的整数转换成2进制 Dim i As Long, j...
在Visual Basic (VB) 中,Do While 循环有两种主要形式:Do While...Loop 和 Do...Loop While。它们的主要区别在于条件检查的时机,这决定了循环体是否执行以及执行的次数。以下是它们的不同点: 1. 条件检查的时机 Do While...Loop 条件检查在循环开始时:在每次迭代开始时,VB 首先检查条件是否为真。
A.没有区别,这两个结构任何情况下效果一样There is no difference,they are the sameB.while循环比do…while循环执行效率高While is more efficient than do-whileC.while循环是先循环后判断,所以循环体至少被执行一次The While loop does the loop first then check the condition, so the loop body can be ...
