Question

我的问题是：编写一个程序，在用户范围（1-99）之间输入一个数字作为输入，并使用多个开关情况将数字转换为单词。如果用户按Enter键，则程序应退出。 [在此输入图像说明] [1]

enter code here
enter code here

我对此问题的解决方案如下，但我没有正常工作，因为字符变量一个得到一个字符。请好好看看＆amp;帮我找到解决这个问题的方法。在这里输入代码

#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;
    case 4:     cout<<"Four";   break;
    case 5:     cout<<"Five";   break;

Answer 1

您使用的是字符，并希望在该变量中存储一个可能包含两个字符的数字
您需要在进入switch语句

int

Answer 2

而不是（它读取单个字符而不是数字）

char a='a';
cout<<"Enter a number: ";
a=getche();

你可以简单地从流中读取整数：

int a;
cout<<"Enter a number: ";
cin>>a;

C ++：如果用户输入数字将其转换为单词并且如果输入按下的程序应该退出，则使用switch case
