Answer 1

choice = n;
改成
n = choice;

你题目的解答代码如下：

#include <iostream>
using namespace std;
int main()
{
    char n, choice;
    while (1)
    {
        cout << "Menu:A(dd) D(elete) S(ort) Q(uit) Select one " << endl;
        cin >> choice;
        n = choice;
        if (n == 'A')
        {
            cout << "数据已经增加" << endl;
            continue;
        }
        else if (n == 'D')
        {
            cout << "数据已经删除" << endl;
            continue;
        }
        else if (n == 'S')
        {
            cout << "数据已经排序" << endl;
            continue;
        }
        else if (n == 'Q')
            break;
    }
    return 0;
}
