While vs Do While Let's consider the previous while loop boolean trigger example. If I had initialized the value of keepGoing as false, the code in the while loop would have never executed and only the word "St

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...

Loop End Sub End Module 解释: Do While count < 5:在每次循环开始时检查条件 count < 5。 如果条件为真,执行循环体中的代码。 count += 1:增加 count 的值。 Loop:返回到 Do While 语句,重新检查条件。 2. Do...Loop While 在这种形式中,循环体至少执行一次,然后在循环结束时检查条件。
用法1是由关键字「WHILE」和「WEND」组成,而用法2由关键字「DO WHILE」和「LOOP」组成,二者表达意思一样。由于2的用法更加丰富和灵活,因此我们见到它的频率也更高些。 上面说了一些比较理论的东西,我们上案例实操一下。 2.while案例实操 案例:根据右侧的富豪等级排名规则,判断左侧各富豪的富豪尊称,将答案写在D列...
Do While 循环条件表达式 语句序列1 [Exit Do] [语句序列2] Loop 语句的语法是先判定是否符合循环的条件,如果符合就执行循环中的语句,否则就结束循环。 同时循环中间,也可以通过嵌套if..then等判断语句来判断是否执行exlt do语句来退出循环。下面举例如下图所示。
