我需要帮助，在此程序中，我想将数字转换为单词

问题描述

// help num2word.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include<iostream>
using namespace std;

     char one[10][10] = {"One", "Two","Three","Four","Five","Six","Seven","Eight","Nine"};
     char ten[15][15] = {"Ten","Eleven","Tweleve","Thirteen","Fourteen","Fifteen","Sixteen","Seventeen","Eighteen","Nineteen"};
     char tens[15][15] = {"Twenty","Thirty","Fourty","Fifty","Sixty","Seventy","Eighty","Ninety"};

int main()
{
	int num , n , r , c = 0 ;
	cout << "please enter the number :" << endl ;
	cin >> num ;

	n = num ;
	while( n )
	{
		r = n % 10 ;
		n = n / 10 ;
		c++ ;
	}

	switch(c)
	{
	case 1:
	  if( num >0 && num < 10 )
	   {
           cout << one[num-1];
	     }else{
		   cout<< "ZERO ";
	    }
		  break;
	   
	case 2:
		/*if( num > 10 && num < 20 )
			cout<<"yay"<<ten[num-10];
		if( num > 20 && num < 100 )
			cout << tens[num/10-2] ;
			*/
		
		  ( num > 10 && num < 20 ) ? (cout << ten[num-10]) :( cout << tens[num/10-1] && ((num%10)?one(num%10):1));
		break;
		
	
	}

	return 0;
}

</iostream>

我的程序从0到19的数字是正确的，但是它不能写55-> 55.
只写五十，我不知道该怎么办?
和ia在((cout< 但我不知道为什么?

my program for numbers from 0 till 19 is true but it cant write 55 ->fifty five
and just write fifty , i dont know what should i do ?
and ia have an error in ((cout << ten[num-10]) :( cout << tens[num/10-1] && ((num%10)?one(num%10):1));)
but i dont know why ?
