根據提問描述,問題涉及C語言While迴圈的執行次數與狀態改變邏輯。關鍵在於: 1. While迴圈條件判斷是在每次迴圈開始前執行。若第一次迴圈將狀態設為"Exit",下一次迴圈條件檢查時即不滿足,迴圈體不會再次執行,因此僅會運行一次。 2. 問題敘述提到「第二次迴圈執行'Exit'狀態結束」,這與C語言的While機制矛盾,...

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...
