为什么 do while 循环不会中断？

Question

我在使用以下代码时遇到问题

switch(adminChoice){
    case 1:
        do{
            cout<<"\nEnter Student ID: ";
            cin>>studentId;
            cout<<"\nEnter Student Name: ";
            cin>>studentName;
            cout<<"\nEnter Student Password: ";
            cin>>studentPassword;
            cout<<"\nAdd another account? y/n ";
            cin>>adminSubChoice;
        }
        while(adminSubChoice!='n' || adminSubChoice !='N');
        break;
    case 2:

当我为 char 变量输入 n 或 N 时，do while 不会中断 adminSubChoice 它会一次又一次地保持运行。有人可以告诉我我做错了什么吗？？

Answer 1

条件 adminSubChoice!='n' || adminSubChoice !='N' 将始终为真，因为没有字符会同时为 n 和 N。

条件应该是adminSubChoice!='n' && adminSubChoice !='N'.
