在C++中将数字转换为英文（1-99）

Question

试图将数字从1-99转换为英文，但我真的不知道我在这里错过了什么。每当我输入一个像20这样的数字时，它就不会像输出20那样输出数字。任何帮助，将不胜感激！ :)

#include <iostream> 
#include <string> 
#include <cstdlib> 

using namespace std; 


int main() 
{ 
    cout << "In this program we will convert integers to English" << endl; 

    int Number, leftDigit, rightDigit, yes; 
    yes = 1; 

    string ones[] = {" Zero" 
        " One " 
        " Two " 
        " Three " 
        " Four " 
        " Five " 
        " Six " 
        " Seven " 
        " Eight " 
        " Nine " 
        " Ten " 
        " Eleven " 
        " Twelve " 
        " Thirteen" 
        " Fourteen " 
        " Fifteen " 
        " Sixteen " 
        " Seventeen " 
        " Eighteen " 
        " Nineteen " }; 

    string tens[] = {" Twenty " 
        " Thirty " 
        " Fourty " 
        " Fifty " 
        " Sixty " 
        " Seventy " 
        " Eighty " 
        " Ninety "}; 
do{ 
    cout << "Enter any integer value: " << endl; 
    cin >> Number; 

    if (Number <= 0 || Number >= 100) 
    { 
     cout << "The number is not between 1 and 99" << endl; 
    } 
    else (Number >= 1 && Number <= 19) 
    { 
     cout << "The number you have entered is: " << ones[Number] << endl; 
    } 
    else (Number >= 20 && Number <= 99) 
    { 
     leftDigit = Number/10; 
     rightDigit = Number % 10; 

     cout << "The number you have entered is: " << tens[leftDigit - 2 ] << " " << ones[rightDigit] << endl; 
    } 
    } while (yes == 1); 

    return 0; 
} 

Answer 1

你有两个问题在你的代码：

首先，你需要把你的参数之间的逗号string ones[]和string tens[]这样的：

string tens[] = { " Twenty ", 
     " Thirty ", 
     " Fourty ", 
     " Fifty ", 
     " Sixty ", 
     " Seventy ", 
     " Eighty ", 
     " Ninety " }; 

二 ，您需要在每个else中添加if，如下所示：

// .. 
else if (Number >= 1 && Number <= 19) 
       { 
        cout << "The number you have entered is: " << ones[Number] << endl; 
       } 
// .. 

结果修复这两个问题后，你的代码：
