Including header

Hi,, I am trying to include a function from a header file named headerfunt.h . The code of my header file is

Code:

---

#ifndef HEADERFUNCT_H_INCLUDED
#define HEADERFUNCT_H_INCLUDED
#include <iostream>
using namespace std;
struct headerfunct{
  int abs(int arg)
{
    if(arg<0)
    {
        return -arg;
    }
    else{return arg;}
}

 };
#endif // HEADERFUNCT_H_INCLUDED

---

and the source code is

Code:

---

#include <iostream>
using namespace std;
#include "headerfunct.h"
int main()
{
int j;
while(cin>>j)
{
    cout<<"Abs of "<<j<<" is "<<abs(j)<<endl;
}
}

---

But, while compiling it says abs was not declared... I have included the file. so wheres the problem. Thanks in advance.

Your implementation of abs() function is declared within headerfunct context, so you need to create an object of this structure.

Thanks. It worked.

Code:

---

#ifndef HEADERFUNCT_H_INCLUDED
#define HEADERFUNCT_H_INCLUDED
#include <iostream>
using namespace std;

  int abs(int arg)

{

    if(arg<0)

    {

        return -arg;

    }

    else{return arg;}

}

 

 #endif // HEADERFUNCT_H_INCLUDED
