c++ 根据编译时间的版本号输出

看了一段代码，根据版本的编译日期生成版本号，觉得很不错，记下来以后可用，哈哈

GetVersion()
{
	std::string monthes[] =  
	{  
		"Jan",  
		"Feb",  
		"Mar",  
		"Apr",  
		"May",  
		"Jun",  
		"Jul",  
		"Aug",  
		"Sep",  
		"Oct",  
		"Nov",  
		"Dec",  
	};  

	std::string dateStr = __DATE__; 

	int year = atoi(dateStr.substr(dateStr.length() - 4).c_str());

	int month = 0;  
	for(int i = 0; i < 12; i++)  
	{  
		if(dateStr.find(monthes[i]) != string::npos)  
		{  
			month = i + 1;  
			break;  
		}  
	}  

	std::string dayStr = dateStr.substr(4, 2);
	int day = atoi(dayStr.c_str());

	std::string timeStr = __TIME__;  

	std::string hourStr = timeStr.substr(0, 2);
	int hour = atoi(hourStr.c_str());

	char version[20];
	sprintf(version, "1.0.%04d%02d%02d%02d", year, month, day, hour);

	return version;
}
