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 have learned about for loops and foreach loops. These loops ...
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 ⋯ lo
Do 做，While 当……时，Loop 循环，Until 直到……时。所以：Do While...Loop：当……时候做XX且循环（先判断条件是否满足，若【满足】，则进入循环，即可能不进入循环）Do...Loop While：做XX且循环，当……时候（先进入循环执行，然后判断条件是否满足，若【满足】，则进入下一次的循环，即循环...
While...Wend语句是可以执行和Do...Loop While语句和Do While...Loop语句相同的程序,他们相当于三胞胎,三者之间可以相互替换,并且最后实现效果都是相同。 结合学生系统中的判断班号是否重复问题:如下图

不一样！前者是在满足while的条件后执行do后的语句，不满足则跳出循环；后者是满足while后的条件后再次执行循环内容。简单来说，后者至少都会执行循环内容一次，而前者可能一次都不会执行。举个例子吧：(1)Dim I As Integer Do While I=1 I=I+1 Loop Msgbox I (2)Dim I As Integer Do I=I+1...
do until 表达式 '循环值到表达式成立为止 语句 loop 2、先执行里面的语句，然后判断loop 后面表达式是否成立，不成立则回到 do 继续循环，否则往下退出循环 do 语句 loop until 表达式 下面两个跟上面差不多的，只是 until 是直到条件满足就退出，而 while 是当条件满足的时候执行。3、do while loop ...
while循环和do...while循环的区别是___。The different between while loop and do-while loop is: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 same.B.while循环比do…while循环执行效率高While is more efficient than do-while.C.
This post will discuss about while loop and do-while loop in Java.. Loops are used to continually execute a block of instructions until a particular condition is satisfied.
There is one major difference you should be aware of when using the do--while loop vs. using a simple while loop: And that is when the check condition is made. In a do--while loop, the test condition evaluation is at the end of the loop. This means that the code inside of the ...
