Multiple File Output in C++ using g++ under Linvux

I am working on a research project in neural networks and need to be able to output sequentially numbered multiple files. I have a loop which performs calculations on an array and outputs a new array. I need to be able to write this array to a different file each time the calculation is performed, preferably sequentially numbered. I have done this about a year ago in Windows but I lost the source and none of my books even touch upon the subject. This is probably a really simple thing to do and I apologise for time wasting, but there is fifty points in it! Cheers.

just create different "numbere " names for the file and store the names in a  string and then use this name when you open the file, like

for (int i = 0; i< 10; ++i)
{
   char FilNam[13];

   sprintf(FilNam,"File%i.txt",i)

   fstream Fil(FilNam,ios_base::out);
}

Let me know if you have any questions.
