c++ - C ++：如果用户输入数字将其转换为单词并且如果按Enter键程序应该退出，则使用切换案例

问题描述

我的问题是：编写一个程序，该程序将用户的数字作为范围（1-99）之间的输入，并通过使用多个 switch 案例将数字转换为单词。如果用户按 Enter，则只有程序应该退出。[在此处输入图片描述][1]

enter code here
enter code here

我对这个问题的解决方案如下，但我没有正常工作，因为字符变量一得到一个字符。请查看并帮助我找到解决此问题的方法。在此处输入代码`

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
char a='a';

cout<<"Enter a number: ";


a=getche(); 

switch(a)
{
    case 1:     cout<<"One";    break;
    case 2:     cout<<"Two";    break;
    case 3:     cout<<"Three";  break;
