What is the error in this code ?!

[xtremee]

Hi all,

I have this C++ code for a program that divide the big files to a small one that have a logic error that i can't find it.

so, i wanna to know where is this logical error? so that i can modifiy this code.

Here is the code:

#include <iostream>

#include <fstream>

#include <sstream>

#include <string>





using namespace std;



int main (int argc, char *argv[]) 

{





 if (argc < 2)

  {

   cout<<"  feilsPart: no input file\n";

   return 1;

  }

 else if (argc < 3)

  {

   cout<<"  feilsPart: no size for the part file in Bytes\n";

   return 1;

  }

 else if (argc < 4)

  {

   cout<<"  feilsPart: no initial name for Part files\n";

   return 1;

  }

 else if (argc < 5)

  {

	cout<<"  feilsPart: no extention for Part files\n";

	return 1;

  }

 else

  {



	   string inputFileName = argv[1];	//  the name of the input file

	   int partSize = atoi(argv[2]);	  //  the size of the part files

	   string partInitialName = argv[3];  //  the initial name for part files.

	   string partExtention = argv[4];	//  the extention name for the part files.





	   // open the Big file

	   ifstream inputFile (inputFileName.c_str());





		if (inputFile.is_open())

		 {

			//  counter to use in nameing of the part files.

			int partCounter = 1;

			while(!inputFile.eof())

			{ 

				bool fileIsNotFull = true;

				//  to save some part of the big file it , then add it to the part file.

		string somePart; 

		ostringstream oss;

				oss <<partInitialName<<partCounter<<"."<<partExtention ;



				// the name of the part file is ready to use.

				string PartFileName = oss.str();



				// open the part file.

				ofstream partFile (PartFileName.c_str());



				// counter for the size of the part file.

				int partSizeCounter = 0;

				if (partFile.is_open())

		{



			while ( (!(partSizeCounter > partSize) && !(partSizeCounter+somePart.size() > partSize)) && fileIsNotFull )

			{



 				  getline (inputFile,somePart);



								  if ( (somePart.size()+ partSizeCounter) < partSize )

								   {

									 partSizeCounter += somePart.size();

									 partFile<<somePart<<endl;

								   }

								  else

									 fileIsNotFull = false;



								cout<<"\r  "<<partSizeCounter;

			}

				partFile.close();

						cout<<"\r  feilsPart: "<<PartFileName<<" Don . size = "<<partSizeCounter<<" Byets"<<endl;

		}

		  // encrese the part counter to change the File name.

			  partCounter++;



			}  //  end of input file.

		  inputFile.close();

		  cout<<"  feilsPart: Finished..";



		} //  Big file is open	else

		else 

		cout<<"  feilsPart: Input file \""<<inputFileName<<"\" can not open\n";

   } // argc

  return 0;

}
