Everything from the standard C++ library should be (and in GCC it is) in the
standard namespace ("std"). You need to either import string into the
current namespace, or qualify the name explicitly.
In other words, either use:
using std::string;
or replace all your string variables from "string" to "std::string".
And while you're at it, read up on the C++ standard (especially namespaces)
:)

Subject: [Dev-C++] 'string' was not declared in this scope
I am trying to compile my program and I got an error:
'string' was not declared in this scope
Even if I put in the file #include <string>
What is happing?
See following my file header:

#define MAX_REPLY_LENGTH 512
#endif
#ifndef CRLF
#define CRLF \r\n
#endif
#ifndef MAX_COMMAND_LENGTH
#define MAX_COMMAND_LENGTH 64
#endif
#ifndef MAX_RECEIPT_BUFFER_SIZE
#define MAX_RECEIPT_BUFFER_SIZE 8192
#endif
//The stat command reply informs the number of messages and the size of
mailbox
#ifndef NUMBER_OF_STAT_REPLY_WORDS
#define NUMBER_OF_STAT_REPLY_WORDS 3 //The reply to STAT command will
give 3 words only
#endif
#ifndef POP3_h
#define POP3_h
#include <string>
#include "SocketConnection.h" //Maybe can occur errors here.
