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...
相关知识点: 试题来源: 解析 A 在Do...Loop While结构中,循环体至少执行一次,然后检查条件。选项A错误,因为即使条件为0(False),循环体也会先执行一次。选项B、C、D都正确:条件可为多种类型;允许Exit Do;True条件导致无限循环。故选A。反馈 收藏
Question: What is a 'do while' loop? Programming Conditions: Computer programs often run some portions of the code base only when certain conditions are present as the code is executed. When running code that loops, or runs repeatedly, it is important to understand the overall controls on the...
