Re: Help with file writing please

The above are pre-standard headers. Some modern compilers don't provide
them. Instead, use

   #include <fstream>
   #include <iostream>


Here you can declare arguments:

   int main( int nArgs, char* args[] )

The argument strings are non-const because 'main' was inherited from C,
but that doesn't mean you can modify them.

The best thing you can do, as a newbie, is to immediately convert the
'main' arguments to a std::vector of std::string, and call a
C++-oriented main function (I usually call it 'cppMain'):

   #include <cstddef> // std::size_t
   #include <string> // std::string
   #include <vector> // std::vector

   // Your additional headers, e.g.
   #include <fstream>
   #include <iostream>

   typedef std::vector<std::string> StringVector;

   void cppMain( StringVector const& arguments )
   {
       using namespace std;

       // Your code goes here, e.g.
       for( size_t i = 0; i < arguments.size(); ++i )
       {
           cout << arguments.at( i ) << endl;
       }
   }

   int main( int nArgs, char* args[] )
   {
       // This can be elaborated on, but as a minimum:
       cppMain( StringVector( args, args + nArgs );
   }


This code would go in 'cppMain' above.

Since you're trying to append text, it would make sense to use the
append mode.

Also, since you're only writing to the stream, it would probably be
better to use std::ofstream instead of the more general std::fstream.
