C++ compiling error:C2872 ambiguous symbol

When I'm using :
#include <iostream.h>
#include<fsteam.h>
#include<string>
using namespace std;

I'm getting this error:
error C2872: 'ostream' : ambiguous symbol

How can I solve it???

Don't mix STL headers with non-standard headers:

#include <iostream>
#include<fsteam>
#include<string>
using namespace std;

Hi reemYaz,

Try replacing the includes with the standard ones (without the .h)

#include <iostream>
#include<fstream>
#include<string>
using namespace std;

Cheers!

Also, <fstream> is mis-splelt as <fsteam>. You forgot to put an 'r' there.

Oh, Tinchos has put it right. By the way, do you need to include <iostream> if <fstream> is already included?

iostream.h is for the old standard (V2), iostream is for the new standard (V3, STL).  Most systems have iostream.h and fstream.h for backward compatibility, and, as mentioned earlier, you shouldn't mix the two.

#include <string> - is using the std namespace

#include <iostream.h> is not in namespace.

namespace concept is to avoid this type of problems.

if u write a function in on library , and another library also contains the same fucntion then u go for specifying a particualr libarary to a namespace.

u want to use <string> ostream then go like std::ostream and declare ur variable
u want to use <iostream.h> ostream then go like ostream and declare ur variable

In the above situation u have to avoid using namespace std;

the sample code is as follows :
#include <iostream.h>
#include <fstream.h>
#include <string>

int main(int argc, char* argv[])
{
      std::ostream    aStringStream ;
      ostream           aIOStream ;
      return 0;
}

i suppose this will clear the picture

thanx
