发几个c++常用小工具的函数（续）

    笔记一直再做项目，随时都会用到一些函数和方法，现在属于一种原始积累状态，将来用到的时候就随便拿来用。省时又省力。。后续还会很多这样的方法。大家也可以去找找。

//取当前日期
string getCurDate()
{
	time_t nowtime;
	time(&nowtime);    //取当前时间值
	struct tm *tPtr;	
	tPtr = localtime(&nowtime);

	char dateStamp[32];
	ACE_OS::sprintf(dateStamp, "%04d%02d%02d", tPtr->tm_year+1900 ,tPtr->tm_mon+1,tPtr->tm_mday);
        
	return dateStamp;
}
//取得当前时间
string getCurTime()
{
	time_t nowtime;
	time(&nowtime);   
	struct tm *tPtr;	
	tPtr = localtime(&nowtime);	

	char timeStamp[15];
    memset(timeStamp, 0x00, 15);
	ACE_OS::sprintf(timeStamp, "%02d%02d%02d", tPtr->tm_hour,tPtr->tm_min,tPtr->tm_sec);
		
	return timeStamp;
}
//int型转string 型
string intToString(int value)
{
    char tmpString[15];
    memset(tmpString, 0x00, 15);
    sprintf(tmpString, "%d", value);
    return  tmpString;
}
//将字符串处理为小写。
void toLower(string &strTmp)
{
    for (unsigned int i = 0; i < strTmp.length(); i++)
    {
        strTmp[i] = tolower(strTmp[i]);
    }
    return;
}
///根据分隔标记flag将字符串放入。。。。
int getItem(string &msg ,  char flag, vector<string> &line)
{
    try
    {
        if (line.size() != 0)
        {
            line.clear();
        }
        
        if (msg.length() == 0)
        {
            return 0;
        }

        char *tmpMsg = &msg[0];

        int begin = 0;
        int end = 0;
        string tmp;
        for (unsigned int i = 0; i < msg.length(); i ++)
        {
            if (tmpMsg[i] == flag)
            {
                end = i;
            }
            else
            {
                continue;
            } 

            if ((end-begin)> 0)
            {             
                 tmp = string(&tmpMsg[begin], end-begin);
            }
            else
            {
                tmp = "";
            }
            begin = end+1;               
            line.push_back(tmp);
         
        }
        if ((msg.length()-begin)> 0)
        {             
            tmp  = string(&tmpMsg[begin], msg.length()-begin);
            line.push_back(tmp);
        }     

    }
    catch(...)
    {
        ACE_DEBUG(( _INFO ACE_TEXT("  getItem execpaction:[%s].\n"), msg.c_str()));
        return -1;
    }
    return 0;
}
输出vector的内容。
void dispVector(const vector<string> &vecTmp)
{
    if (vecTmp.size() == 0)
    {
        ACE_DEBUG(( _INFO ACE_TEXT( " vector is null\n" )));
        return;        
    }
    
    for (unsigned int i = 0 ; i < vecTmp.size(); i++)
    {
        ACE_DEBUG(( _INFO ACE_TEXT( "  [%25s]\n" ), vecTmp[i].c_str()));        
    }

    return ;
}
返回num后的字符串
string lastStr(string &from, int num)
{
    if (from.length() <= (unsigned int)num)
    {
        return from;
    }
    else
    {
        return from.substr(from.length()-num, num);
    }
}

string leftFullChar(string &from, int count, char flag)
{
    if (from.length() > (unsigned int)count)
    {
        return from ;
    }

    int fullCount  = (int)from.length() - count;
    string strTmp(fullCount, flag);
    strTmp += from;
    return strTmp;
}

string rightFullChar(string &from, int count, char flag)
{
    if (from.length() > (unsigned int)count)
    {
        return from ;
    }

    int fullCount  = (int)from.length() - count;
    string strTmp(fullCount, flag);
    return from+strTmp;
}
