为什么相同的循环逻辑（标红）在showcode最后可以用，但是openaccount不可以

就是我每次在每个功能进行一次后在结尾询问是否要继续后， showcode的可以正确执行，但是openaccount的就不可以 解决了，就是直接在主程序菜单的switch的case 2里写一个do...while来控制是否进行循环 真的很疑惑，求助各位大佬！ 本帖最后由 jackz007 于 2020-12-22 18:06 编辑
楼主，把你的帖子编辑一下，一定要把代码贴进代码框，要不然，你贴出来的代码会缺很多东西，看看你的代码，是不是在某个位置起变成斜体了，因为你的部分代码被作为字体及其它版面描述符而被吸收掉了。 jackz007 发表于 2020-12-22 18:04

代码框不是那个发帖的时候下面那个大框吗 空羊羊 发表于 2020-12-22 18:20

不是的，是这个框子的上边框有一个标识有 "<>" 的按钮，点一下就会出现代码框。 jackz007 发表于 2020-12-22 18:27
