Largest()
bool getnext()
unsigned long value()const

i need help how to begin
i need
Largest.h

Don't use #pragma once it is compiler specific. Here is what your H file might look like, keep in mind you will have to write the function implementation in the accompanying cpp file.

Code:

#ifndef LARGEST_H 
#define LARGEST_H

class Largest
{
  private:
    unsigned long m_foo;
    unsigned long m_foo2;

  public:
    Largest( ); // Constructor
    ~Largest( ); // Destructor
    bool getNext( );
    unsigned long value( ) const;
};

#endif /* LARGEST_H */

Use those #ifndef's for inclusion guards instead of #pragma once. Post back if you have more questions.

OOPS: To create an instance of this class in your main code, simply use the following syntax.

Largest MyLargeList;

Where Largest is the class you want to create an instance of and MyLargeList is the variable name.
