将多个int 或其他类型的数据 拼接在一起并转成string类型

int iYear = 2015;int iMonth = 2;int iDay = 10;int iHour = 12;int iMinute = 31;char chTime[30];string strTime;int iLength = 0;iLength += sprintf(chTime,"%d",iYear);*(&chTime[iLength]) = '.';iLength ++;iLength += sprintf(&chTime[iLength],"%d",iMonth);*(&chTime[iLength]) = '.';iLength ++;iLength += sprintf(&chTime[iLength],"%d",iDay);*(&chTime[iLength]) = '.';iLength ++;iLength += sprintf(&chTime[iLength],"%d",iHour);*(&chTime[iLength]) = ':';iLength ++;iLength += sprintf(&chTime[iLength],"%d",iMinute);strTime = chTime;
