Re: help with visual c++

Read any book about C++ and namespaces.

Replace this line
#include using namespace std;

With this one:
using namespace std;

Re: help with visual c++

Dear ...
U have used #include using namespace std; which is totally wrong actually it will be using namespace std; because -

using namespace std;

All the elements of the standard C++ library are declared within what is called a namespace, the namespace with the name std. So in order to access its functionality we declare with this expression that we will be using these entities. This line is very frequent in C++ programs that use the standard library, and in fact it will be included in most of the source codes included in these tutorials.

and #include is usually used for including the Hidder files in ur program... it is called preprocessor directives

have a Good Day... []

help with visual c++

well
open this file:

C:\Program files\Visual Studio\VC\header files

and check for header file names you have typed to see if they are exists.

help with visual c++

replace
#include using namespace std;
with
using namespace std;
in the fourth line

i hope it will work
