Question

Please help me on this, its really irritating may be because i am doing it for the first time and have no experience.

Aim : to find factorial of a number

.
.
STEP 1: Creating new project of type VC++ MFC and in templates MFC DLL

STEP 2: Then comes create a regular DLL (MFC shared) i say Yes

STEP 3: I create header file (ServerHeader.h) with the following code

_declspec (dllimport) int factorial(int no);

STEP 4 : I create cpp file (ServerFactorial.cpp) with the code

#include "stdafx.h" 
_declspec (dllexport) int factorial(int no)
{


return no == 0 ? 1 : no * factorial(no-1);
}

STEP 5 : i BUILD the project and everything is fine

STEP 6 : I create another project Client of VC++ Win32 and in templates Win32 Console Application with application setting as EMPTY PROJECT and create a new cpp file (MainClass.cpp) with the code

#include "ServerHeader.h"

#include <iostream.h>

void main()
{


int no,i;


cout<<"Enter number";


cin>>no;


i=factorial(n);  // calling the method


cout<<endl<<i;   // printing ans

}

STEP 7 : I copy the ServerHeader.h, Server.dll, Server.lib (there are 2 library files, one is Object and other is Export) i copy all 4 from Server to Client

STEP 8: Right click on Client project set the linker’s general setting and write the path of my lib file which i copied in Client project folder

STEP 9: i build my project i get

Error 1 fatal error C1083: Cannot open include file: ‘iostream.h’: No such file or directory f:\client\client\mainclass.cpp 2 Client

Sorry for such a long post.

Answer 1

It should be #include <iostream> then you need to include the namespace, std::cout, or include a using namespace std statement in your code.
