Problem with classes

[abeginner23235616]

I was trying to access the classes from different files. So , like a normal procedure, I made a new class, added the required codes and added the necessary preprocessor. But when i try to run the program, it says that my class has not been declared. I am not able to understand the cause. I am providing you the codes. Please help me out!

  //the main file.cpp....................

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

using namespace std;

int main()
{
    sally a(23);
    sally b(87);
    sally c;
    c=a+b; // it gonna run operator+
    cout<<c.num;
    return 0;
}

____________________

#ifndef SALLY_H
#define SALLY_H


class sally //my custom class, header file
{
    public:
        int num;
        sally();
        sally(int);
       sally operator+(sally);
};

#endif // SALLY_H 

____________________________

#include "sally.h"  //the sally.cpp
#include<iosream.h>
using namespace std;
sally::sally()
{
  num=a;
}

sally sally :: operator+(sally aso){
sally Aobject;
Aobject.num=num+aso.num;
return (Aobject);
}

Thanks in advance!

What file is iosream.h, which is found in sally.cpp, line 2?

Did you make sure you added the files to your project file? This is different than the preprocessor directives. I know that for at least Code::Blocks, you have to both use #include and "add" files to the project.

Also there are four mistakes with your sally.cpp file.
1) The default constructor, sally(), makes use of a non-existent "a" variable.
2) There is no definition for the sally(int) constructor.
3) You misspelled iostream
4) You are using a deprecated iostream.h header. Just use iostream as you did in your main.cpp file.
