error c2011 when creating multiple classes

[Patrick Burton]

I've searched the forum for a similar error with no success. Here's the code:

this is the main class "test.cpp."

#include <iostream>;
#include "class1.h"

using namespace std;


int main(){

        class1 test;
        int x,y;

        cin >> x;

        cin >> y;
        test.setSomething(x,y);
        test.printSomething();

    return 0;

}

class1.h

#ifndef CLASS1_H
#define CLASS1_H

class class1{

    public:

        void setSomething(int, int);
        void printSomething();

    private:

        int x;
        int y;



};

#endif

class1.cpp

#include "class1.h"

using namespace std;

class class1{


            void class1::setSomething(int x, int y){

                class1::x = x;
                class1::y = y;

            }//end class1

            void class1::printSomething(){

                cout << "the sum is: " << (x+y) << " .\n";

            }

};

I receive error c2011, the full error below. There are other errors as well.

D:\...\proj1\test.cpp|1|warning C4067: unexpected tokens following preprocessor directive - expected a newline|

Any help would be greatly appreciated.

class1.cpp

#include "class1.h"

#include <iostream>

using namespace std;



            void class1::setSomething(int x, int y){

                class1::x = x;
                class1::y = y;

            }//end class1

            void class1::printSomething(){

                cout << "the sum is: " << (x+y) << " .\n";

            }

Thanks so much! However, I receive the errors:

D:\...\proj1\test.cpp|1|warning C4067: unexpected tokens following preprocessor directive - expected a newline|
C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\xlocale|342|warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify /EHsc|

One error in specific I'm curious about is the error LNK2019.

#include <iostream>; // Khm-khm
On my VS2008 it compiles and works. Try to remake the project (delete project and make new).

[Patrick Burton]

I created a brand new project in VS2008 with the same code as above (adding #include <iostream>;) and receive the same C2011 error. Here's the error according to VS2008

1>------ Build started: Project: test, Configuration: Debug Win32 ------

I meant: don't write ';' after #include <iostream>.
Try this:

main.cpp

#include <iostream>
#include "class1.h"

using namespace std;


int main(){

        class1 test;
        int x,y;

        cin >> x;

        cin >> y;
        test.setSomething(x,y);
        test.printSomething();

    return 0;

}

class1.cpp

#include "class1.h"

#include <iostream>

using namespace std;



            void class1::setSomething(int x, int y){

                class1::x = x;
                class1::y = y;

            }//end class1

            void class1::printSomething(){

                cout << "the sum is: " << (x+y) << " .\n";

            }

class1.h

 #pragma once

class class1{

    public:

        void setSomething(int, int);
        void printSomething();

    private:

        int x;
        int y;



};

Still receiving the same error, c2011.

I recompiled this code (from my last post) and all successed. I don't know, why you have problems.

[Patrick Burton]

Found the problem, just a minor typo. Worked when I copied and pasted everything exactly as it was. Thanks so much!!
