答案:C. 解:当计算机遇到While语句时,先判断条件的真假,若条件符合,就执行循环体; 若条件不符合,则不执行循环体,直接跳到END后的语句. 故选C. 本题是一道考查循环语句的题目,掌握Do Loop语句的特点以及循环语句的结构是解答本题的关键; 首先根据题设条件,由Do Loop语句的特点,当计算机遇到While语句时,先判断条...
解析 C 正确答案:C解析:Do…Loop while∣until采用的是先执行循环体后判断条件的做法,首先执行循环,之后进行条件判断,无论条件真假,循环体都会至少执行一次。因此选项C正确,而其他三个循环语句都会首先进行条件判断,若条件为假,则不进入循环体。反馈 收藏 ...
Do…Loop循环 功能:当循环“条件”为真(While条件)或直到指定的循环结束“条件”(Until〈条件〉)为真之前重复执行“循环体”。 形式1: Do [While| Until〈条件〉] [〈循环体〉] [Exit Do] Loop 形式2: Do [〈循环体〉] [Exit Do] Loop [ ...

We use a Do While loop to loop through the cells in column C until an empty cell is encountered. We check if the current cell is not empty using the condition Value <> “”. Inside the loop, we use the Cells property of the outputSheet object to write the value of the current cell...
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 ...
