RE: [Dev-C++] 'string' was not declared in this scope

[P.D. v. Z. <pa...@my...>]

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)
:)

Paul

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:

#endif

#endif

mailbox
