[藍橋杯]試題 基礎練習 數的讀法

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

using namespace std;

int main()
{
	string str;
	cin>>str;
	int n = str.size();
	
	string nums[10] ={"ling","yi","er","san","si","wu","liu","qi","ba","jiu"};
	string units[11] = {"","","shi","bai","qian","wan","shi","bai","qian","yi","shi"};

	for(int i = 0; i < n; i++)
	{
		int num = str[i] - '0';
		if(num == 0)
		{
			if(i + 1 < n && str[i+1] != '0')
			{//下一個不是0,才輸出ling 
				cout<<nums[num]<<" ";
			}
		}
		else if((n - i == 2 || n - i == 6 || n - i == 10) && num == 1)
		{//10幾而不是20、30幾的時候輸出shi,而不 yi shi 
			 cout<<units[n-i]<<" ";
		}
		else
		{
			cout<<nums[num]<<" "<<units[n-i]<<" "; 
		}
	} 
	return 0;
}

參考：他的有點小問題 50101這種答案不對
