I thought that the syntax for c++ in either winXP or linux was the
same.

In Ubuntu linux it works fine if I write:

#include <string>
using namespace std;

int main()
{
string bb = "fff";
std::cout << bb;
return 0;

}

But in winXP in MS Visual Studio 2005 'cout' is not recognized in 'std'

I also have to declare a string like: std::string s = "ffff". Why does
'using namespace std' not work in winXP.

What are there reason for this and are there many cases where C++
syntax in linux is not compatible with C++ syntax for MS Visual Studio?

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

int main()
{
.......
}

The problem was that I typed 'using namespace std;' in a header file.
It seems that this is a wrong use and it should be typed in each source
file.

No, that is not the problem; there is no header file in your example in
which you could have typed the using directive. The problem as others
have noted is the missing #include <iostream>
