I am new to C++.  I am trying to make "get" provide the same
functionality that "fgets" provides in C...namely, to read in 
successive lines of input for processing.  However, I am 
having problems with the newline character, which, get(char *) 
skips on the first scan, and on the next scan sees as the first 
character, and reads in an empty line.  Thus only the first 
line is read in correctly, and all the other lines are skipped.
I have enclosed a test code and typical output.

Is "get" the right function for my purpose ?  If so, how can
I get over this '\n' problem ?  In C++, which function does
one normally use to read in a file, and process each line ?

Thanks for any help,
Ramesh

---------------------- TEST CODE ---------------------

 main(int argc, char* argv[])
 {
    filebuf fin;
    if (fin.open(argv[1],input) == 0)
            error("cannot open input file", argv[1]);
    istream from(&fin);

    char linebuf[80];

    while(from.get(linebuf,80,'\n') && !from.eof())    
      {
cout << "Read in this line: " << linebuf << "\n" ;  
getchar(); 
      }
}
