关于while语句的问题

Question

为什么还要加cin.get(ch)？

Answer 1

那是你循环的判断条件，你的程序简写如下：cin.get(ch);while(ch != '.'){...cin.get(ch);}所以，每次循环完了都得输入ch来进行下一次循环，当ch = '.'时退出循环。

Answer 2

cin.get(ch);           //这里的cin.get(ch)获得第一个字符 while (ch != '.') {    //ch为'.'就退出循环     if (ch == ' ')     //ch为空格space就+1         ++space;     ++total;           //每get一个字符，total+1     cin.get(ch);       //获取下一个字符 }循环体中的cin.get(ch)是为了逐个获取整句话的每一个字符。如果满足要求，望采纳！<(▰˘◡˘▰)>
