C++ Help with file handle and simple statistics problem asking...

Input_file:
Code:
>header_1
ASDFFDASADASF
>header_2
ASDSAFASDAAFFFAFA

Desired output file:
Code:
30

Source Code try:
Code:
// reading a text file
#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main () {
  string line;
  ifstream myfile ("Input_file");
  if (myfile.is_open())
  {
    while ( myfile.good() )
    {
      getline (myfile,line);
      cout << line << endl;
    }
    myfile.close();
  }

  else cout << "Unable to open file";

  return 0;
}

I only have idea to read the file.
Unfortunately, I don't know how to use the content inside input file to calculate its total number of content besides ">" Smilie
Apart from that, how should I do in order to let the program analysis any type of file instead of specific input file name at the source code?
eg.
Code:
program_name any_input_file_name output_file_name

program_name refers to the program that help to calculate the content in any type of input_file except ">";
any_input_file_name refer to the any input file name as long as its content is contain ">" and its respectively content;
output_file_name refer to the total character in the input_file exclude ">". In my case, output_file_name should shown "30"
Thanks for any advice.

Also to make it accurate we need to inlcude fullpath of the file. Is there another command that can tell if a file has a truely active... (12 Replies)

ftp_alloc - Allocates space for a file to be uploaded

SYNOPSIS
bool ftp_alloc (resource $ftp_stream, int $filesize, [string &$result]) DESCRIPTION
Sends an ALLO command to the remote FTP server to allocate space for a file to be uploaded. Note Many FTP servers do not support this command. These servers may return a failure code ( FALSE) indicating the command is not sup- ported or a success code ( TRUE) to indicate that pre-allocation is not necessary and the client should continue as though the oper- ation were successful. Because of this, it may be best to reserve this function for servers which explicitly require preallocation. PARAMETERS
o $ftp_stream - The link identifier of the FTP connection. o $filesize - The number of bytes to allocate. o $result - A textual representation of the servers response will be returned by reference in $result if a variable is provided. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 ftp_alloc(3) example <?php $file = "/home/user/myfile"; // connect to the server $conn_id = ftp_connect('ftp.example.com'); $login_result = ftp_login($conn_id, 'anonymous', 'user@example.com'); if (ftp_alloc($conn_id, filesize($file), $result)) { echo "Space successfully allocated on server. Sending $file. "; ftp_put($conn_id, '/incomming/myfile', $file, FTP_BINARY); } else { echo "Unable to allocate space on server. Server said: $result "; } ftp_close($conn_id); ?> SEE ALSO
