    Simple simple program

    Hello, I have this very simple program which won't compile. Please help me!

    Code:
    #include <iostream>
    #include <string>
    #include "stdafx.h"
    
    
    int main()
    {
    	std::string name("This is a test!");
    	
    	std::cout << name << std::endl;
    
    
    	return 0;
    }
    I get the error:
    error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)

    I am using Visual c++ .NET. Can someone please tell me why this doesn't work?

    thanks!

    Yep worked for me, of course in dev-c++ I removed the "stdafx.h".
    What is C++?

    I would remove the stdafx.h, simply because in this case there is absolutely no use for it. Other than that however, I see nothing syntactically wrong with your code - unless of course the C++ standard does not allow use of std::string with cout's << operator, which I highly doubt since nearly every compiler allows it.

    If you want it to *work* though, try using name.c_str() instead of name. It is guaranteed to be supported by the standard. And if that doesn't work, then you know your compiler's screwed
    Just Google It. √

    Thanks all for the help. I found some more information. When I create my project in Visual Studio I am choosing a "Win32 Console Project". This is why the #include "stdafx.h" line is there (and cannot be removed). But the program does not work. But here is what else I discovered: if I instead create a "Console Application (.NET)" project, the program will work without any errors.

    Does anyone have experience with Visual Studio who can help?

    Thanks guys.

    move the line
    #include "stdafx.h"

    To the top of your includes. stdafx.h must always be included first.

    Remove it, and then turn off "precompiled headers" in the project settings.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    If you want to run just a simple console app, select win32 >> then console project, when the application wizzard dialog pops up select application settings and then select Empty project. After the solution loads up right click source files and select add >> then new item >> from the list of templates select cpp.

    that will give you a project without the stdafx.h header files.
    then just add your code from the book.
