Need help with Visual Studio C++

[hnaderi]

Hey, i hope someone out here can help me out. I've recently switched to visual studio pro 6.0 to finsih up this school project, but i can't seem to run a simple program on it at all! I get errors when i even try to output to the console or when i include standard libraries (string, ifstream). For instance, here is an error code for the following line of code:

string word = "testword";

error C2065: 'string' : undeclared identifier


I did put in the include statement:
#include <string>
also tried
#include <string.h>

isn't string part of the standard library of C++? Why is visual c++ giving me so many problems? did i not set up the project correctly? Please hep!!

I don't think string.h actually gives you a string datatype. I usually use it to have access to string related functions like memcpy and strcpy which take arrays of chars or char pointers.

VS6 is very, very old and it's known to have gaping holes in it's C++ standards support, but I don't think strings is one of those since it's a pretty basic datatype. Did you even try looking in the MSDN docs that came with it?

Looked up <string> in VS.NET

// basic_string_ctor.cpp
// compile with: /EHsc
#include <string>
#include <iostream>

void main( )
{
using namespace std;

// The first member function initializing with a C-string
const char *cstr1a = "Hello Out There.";
basic_string <char> str1a ( cstr1a , 5);
cout << "The string initialized by C-string cstr1a is: "
<< str1a << "." << endl;

// The second member function initializing with a string
string str2a ( "How Do You Do?" );
basic_string <char> str2b ( str2a , 7 , 7 );
cout << "The string initialized by part of the string cstr2a is: "
<< str2b << "." << endl;

// The third member function initializing a string
// with a number of characters of a specific value
basic_string <char> str3a ( 5, '9' );
cout << "The string initialized by five number 9s is: "
<< str3a << endl;

// The fourth member function creates an empty string
// and string with a specified allocator
basic_string <char> str4a;
string str4b;
basic_string <char> str4c ( str4b.get_allocator( ) );
if (str4c.empty ( ) )
cout << "The string str4c is empty." << endl;
else
cout << "The string str4c is not empty." << endl;

// The fifth member function initializes a string from
// another range of characters
string str5a ( "Hello World" );
basic_string <char> str5b ( str5a.begin ( ) + 5 , str5a.end ( ) );
cout << "The string initialized by another range is: "
<< str5b << "." << endl;
}

#include <string>

but also put a using namespace std; statement after the includes, because string should be part of the namespace std <-- i don't remember if VC6 observes this rule but it's worth a try

you can also access string like this: std::string blah = "dafd"; without the using statement (note the std:: )

vc6 does have the string (and other STL classes) in the "std" namespace.

great, thanks for all the help guys, the problem was i didn't include :

using namespace std;

I had actually put that line before all my #include's, which ended up in a compiler error and so had then commented it out, after putting it after everything is as sweet and dandy like sour candy (as ned flanders would say it)
