Multiple Source File Problem in C++

I had a a problem in implementing a Multiple Source File

My function is like this:

inline bool TextContains(char *text, char ch) {
  while ( *text ) {
    if ( *text++ == ch )
      return true;
  }
  return false;
}

void Split(char *text, char *delims, vector<string> &words) {
  int beg;
  for (int i = 0; text[i]; ++i) {

    while ( text[i] && TextContains(delims, text[i]) )
      ++i;

    beg = i;

    while ( text[i] && !TextContains(delims, text[i]) )
      ++i;
      words.push_back( string(&text[beg], &text[i]) );
    }
}

string convertInt(int number)
{
   stringstream ss;
   ss << number;
   return ss.str();
}


string dateFormatChecker(const char *date){
string strdate=date;
char getdate[50];
strcpy_s(getdate, strdate.c_str());

vector<string> checkdate;
Split( getdate, "-", checkdate );
int year, month, day;
year=atoi(checkdate[0].c_str());
month=atoi(checkdate[1].c_str());
day=atoi(checkdate[2].c_str());

string checkyear, checkmonth, checkday, checkhour, checkminute, checksecond;

        checkyear = convertInt(year);
        if(month<10){
        checkmonth = "0" + convertInt(month);
        }
        else{
        checkmonth = convertInt(month);
        }
        if(day<10){

        }
        else{
        checkday = convertInt(day);

  char SN[11], RSI[200], WSI[200], BDD[100], BDT[100], STT[100], ETT[100], EDT[100], RD[100];

  strcpy_s(SN, words[0].c_str());
  strcpy_s(RSI, words[1].c_str());
  strcpy_s(WSI, words[2].c_str()); 
  strcpy_s(BDD, words[3].c_str());

  string PosData;
  PosData = FormatPosDataXml(SN,RSI,WSI,BDD,BDT,STT,ETT,EDT,RD);

return PosData;

}

But whenever I put it in the header file like this :

string getInput(char *data);

I always get plenty of errors like undeclared identifier, int string redefinition and so on...

Anyone can you help me?

I think the order of header #includes might be the source of the problem.

Regarding this error:

'string' is not a valid template type argument for parameter '_Ty'

and

ambiguous symbol 'std::vector'

Are you being consistent with your usage of "std::" versus "using namespace std;"?

tnx for the information guys.. i finally got the right codes.

first i must put headers on the function so that it wont prompt some errors.

THen I will remove the usual header except the header that i made. and then I got it...
