What is wrong with this simple code!?

[IWP506]

10 points (and a cookie) to whoever tells me why this code generates
these errors:

C:\Programming\ Microsoft Visual Studio\MyProjec ts\HelloWorld\m ain.c(5)
: error C2065: 'cout' : undeclared identifier
C:\Programming\ Microsoft Visual Studio\MyProjec ts\HelloWorld\m ain.c(5)
: error C2297: '<<' : illegal, right operand has type 'char [2]'

#include <iostream.h>

int main()
{
cout << "h";
return 0;
}

Thanks

Should be

#include <iostream>
using std::cout;

int main()
{
cout << "h";
return 0;
}

Rename the file to .cpp or .C or .cxx or .c++ or anything that would
make it a C++ source file. Your compiler apparently attempts to treat
it as a C source file.

It should be
#include <iostream>
int main()
{
cout << "h";

std::cout << "h" << std::endl;

I see... so I could using "using namespace std;" then if I wanted to
just make it "cout" and not "std::cout" ?

BTW, thanks for the uberly quick responses.

The namespaces are there for a reason, so your code does not trip-over some
other library code, so it is not a good idea just to discard the namespaces.
Try getting use to writing std:: and use namespaces in your own code too..
with code completion and copy & paste it really is not that hard to get used
to..

In addition:

C:\Programming\ Microsoft Visual Studio\MyProjec ts\HelloWorld\m ain.c

If you haven't changed anything else, than VC++ assumes this is C code not C++.
For C++ use a file extension of *.cpp
