本文介绍了一个C++程序，该程序能够将数字转换成特定格式的字符串，并能将这些字符串反转换回数字。通过使用字符串数组和映射，程序实现了从数字到字符串及从字符串到数字的有效转换。

#include<cstdio>
#include<cstring>
#include<algorithm>
#include<map>
#include<iostream>
#include<string>
using namespace std;

string unitdigit[13]={"tret","jan","feb","mar","apr","may","jun","jly","aug","sep","oct","nov","dec"};
string tendigit[13]={"tret","tam","hel","maa","huh","tou","kes","hei","elo","syy","lok","mer","jou"};
string numtostring[170];
map<string,int> stringtonum;
void init()
{
	for(int i=0;i<=12;i++)
	{
		numtostring[i]=unitdigit[i];
		stringtonum[unitdigit[i]]=i;//十位数为0
		numtostring[i*13]=tendigit[i];
		stringtonum[tendigit[i]]=i*13;//个位数是0
	}
	for(int i=1;i<=12;i++)
	{
		for(int j=1;j<=12;j++)
		{
			string str=tendigit[i]+" "+unitdigit[j];
			numtostring[i*13+j]=str;
			stringtonum[str]=i*13+j;
		}
	}
	
}

int main()
{
	init();
	int n;
	scanf("%d%*c",&n);
	while(n--)
	{
		string str;
		getline(cin,str);
		if(str[0]>='0'&&str[0]<='9')
		{
			int num=0;
			for(int i=0;i<str.length();i++)
				num=num*10+(str[i]-'0');
			cout << numtostring[num] << endl;
		}
		else
		{
			cout << stringtonum[str] << endl;			
		}
		
	}
	system("pause");
	return 0;
