Standard C++ file I/O

We want to use C++ to read a text file line by line, sort the content and write the result back to a new text file. We assume the file size is small enough to fit into the memory, several edge cases are not covered; although the power of STL will cover most of them!

 //See: http://www.cppreference.com/cppio/index.html //The  library allows programmers to do file //input and output with the ifstream and ofstream classes #include  #include  #include  #include   using namespace std;  int main(int argc, char* argv[]) {   const static char* InputFilePath  = argv[1];   const static char* OutputFilePath = argv[2];    //At least two arguments must be provided   if(argc != 3)   {     cout << "The first argument is the input file path,"       " and the second one is the output file path" <<> setFileData;    //Read Data   ifstream fileInput(InputFilePath);   copy( istream_iterator (fileInput)         , istream_iterator ()         , inserter(setFileData, setFileData.begin()) );    //Write Sorted Data   ofstream fileOutput(OutputFilePath);   copy( setFileData.begin()         , setFileData.end()         , ostream_iterator(fileOutput, "\n"));    return 1;
