Hello,
I have to parsing (and to do something) with lines read from a file like 10,50,30,4 (10,22,3,^,22 -> the ^ means the line contains an error so I have to reject it)...
My code seems ok and it's this:
Qt Code: 
  1. const char delim=',';
  2. void myFunction(vector<string>& lineOfFile, const char& delim) {
  3. 	vector<string>::iterator it = lineOfFile.begin();
  4. 	for( ;it != lineOfFile.end(); ++it) {
  5. 		vector<double> line; 		
  6. 		size_t pStart=-1;
  7. 		size_t pEnd=-2;
  8. 		double val;
  9. 		string subStr("");
  10.  		bool lineIsOk = true;
  11. 		while (pEnd != -1 && lineIsOk) {							
  12. 				pStart = (int) (*it).find(delim, pStart+1);				
  13. 				pEnd = (int) (*it).find(delim, pStart+1);	
  14. 				subStr = (*it).substr(pStart+1, pEnd-1 - pStart );  
  15. 				if (subStr != "^" ) {  
  16. 					val = (double) atof( subStr.c_str() ); 
  17. 					subStr=""; 
  18. 					line.push_back(val); 
  19. 				}
  20. 				else { lineIsOk = false; }
  21. 		}
  22. 		if ( lineIsOk) insertInOtherStruvture(line);
  23. 	}

Problem now is that this is working only delim=',' and I'd like parsing that line in way like mine (it seems simple, doens't it?) but with other delim for example, I'd like cover line like
10 2 22 200 1
or
10 space space space 22 space 2 33
if the creator of file don't create the file correct with more space (but I'd like to parse it how it was)



Could you help me, please? thanks a lot.
