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...

总结:until 是排除条件。不否和条件的,才执行命令;while 是只执行条件。只有满足才执行命令。PS: Exit Do 仅可以用在 Do...Loop 循环语句中,提供另一种退出 Do...Loop 的方法。可以在 Do...Loop 语句中的任何位置放置任意个 Exit Do。Exit Do 通常与条件判断语句(如 If...Then )一起使用,将控制...
The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.Syntax do { // code block to be executed } while (condition); ...
上一篇聊过了以指定次数执行语句的FOR NEXT循环,但是当我们不知道循环具体会运行多少次,但能通过某种条件的变化来实现控制循环的开始和结束,这便是今天咱们要聊聊的的DO…Loop循环。 一、当条件为 True 时重复语句 语法: 1.条件前置 Do While 条件表达式 ...
VBA Do while is a loop in which you need to specify a condition and that condition must remain true for the loop to run. In simple words, first, it checks that the condition you have specified is true or not and if that condition is true it runs the loop, otherwise nothing. ...
The value of the counter variable increments by 1 on each iteration and the do loop will continue to iterate until its value is less than 10. When the value of the counter becomes 10 the while condition becomes false and the do loop will exit. iNumber = 10 counter = 0 Do While ...
解析 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 Intege...结果一 题目 VB中的do while……loop 和do……loop while语句是一样的吗 答案 不一...
In while loops you can check some condition before starting each iteration and it runs while the condition is true. In do...while loops you check the condition after each iteration. Thus do...while loops always run at least once. for loops are more suitable when you have some iterator or...
