c++ - 使用开关，但我想使用字符串而不是int进行选择

Question

下面的代码只是主要部分，不包括头文件或其他cpp文件。在程序末尾，我想将用户的选择打印到一个csv文件中。除非我可以更改用户做出选择的方式，否则我不会看到如何做。
1.我可以使用其他int来进行用户选择吗？
2.如果我能够根据用户的选择执行除int之外的其他操作，那么像到目前为止一样，只在最后打印到csv代码即可吗？

#include <iomanip>
#include <iostream>
#include <string>
#include <cstdlib>
#include <fstream>
#include "Header.h"
using namespace std;

您可以使用字符串在用户选择的菜单选项之间进行比较。

string choice = " ";
cout<<"Enter choice "<<endl;
cin>>choice;
