From a .txtfile to another

[Coding]

I am trying to resort a few lines in "Main.txt" to another file, "Main1.txt".
The lines look like this in "Main.txt":

12/03/1999,12/04/1999,1535
12/03/1999,12/04/1999,1537
12/03/1999,12/04/1999,1538

When using this code my output look like this:
It seems that string/int Two/Three did work but not One
I beleive it has to do with getline in anyway but cant figure it out really ?


12/04/1999,1535,2,12/03/1999
12/04/1999,1537,2,03/1999
12/04/1999,1538,2,03/1999

	int Three = 0;

  	ifstream NewFile ("Main.txt");
	NewOutFile.open ("Main1.txt");
	
		while	(    getline(NewFile, One, ',')   )           		
		{
			NewFile >> Two;				
			NewFile >> Comma;			
			NewFile >> Three;			
			NewFile.get();				// read in trailing newline character

			NewOutFile << Two  << ',' << Three  << ',' << One  << "\n";
		}

return 0;
}

Why not read the whole line into a string, and then an inner loop with a stringstream delimited by commas?

I am not sure how to do that really. I have used this method before and it has worked but it is strange why this is not working now. There has just to be a small mistake somewhere I think...

[Dave_Sinkula]

I was dreaming up something like:

#include <iostream>
#include <fstream>
#include <sstream> 
#include <string>  

int main()
{
   std::ifstream input  ("Main.txt");
   std::ofstream output ("Main1.txt");
   std::string line;
   while ( std::getline(input, line) )
   {
      std::istringstream iss(line);
      std::string start, end;
      int value;
      while ( std::getline(iss, start, ',') &&
              std::getline(iss, end,   ',') &&
              iss >> value )
      {
         output << start  << ',' << value << ",2," << end << "\n";
      }
   }
   return 0;
}

Yes, this did work great actually. I have never used this method before.
Thank you for this solution...

That is just a smidgen of the power of the standard library, if you want to learn a lot more about that sort of stuff, I would recommend Thinking in C++, free from Bruce Eckel's website

[Coding]

Great! I will look that up. Thanks for the tip also.
