Thread: 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.
