Question Object Oriented Programming

I would like to tell me how can I create a simple object with the data and methods for a database.In other words,the object should be called "SoundCard" and the data should be the specifications of a sound card.The methods will be something like choose this sound card.
Just give an idea.
Thank you.

Download and read chapter one of this book, written by Bruce Eckel:

Thinking in C++, 2nd Edition, Volume 1
Thinking in C++, 2nd Edition, Volume 2

http://www.xtremejava.com/books/index.html

This will provide you some background in OOP. When you have that down, you can read the other chapters to get a handle on the syntax of C++.

But, for quick reference, here's a small and woefully imcomplete sample:

Code:
// Class declaration
class CSoundCard
{
public:
   CSoundCard();
   int GetSpec1() { return m_nSpec1; }
   void SetSpec1(int nSpec1);
private:
   int m_nSpec1;
};

// Class implementation

// Class constructor
CSoundCard::CSoundCard()
{
   m_nSpec1 = 1;
}

// Data access method
void CSoundCard::SetSpec1(int nSpec1)
{
   m_nSpec1 = nSpec1;
}


Now, to use this class, simply include the header file into your main program file (e.g., main.cpp) and create and use an object of type CSoundCard.

Code:
...  // Normal includes go here
#include "SoundCard.h"

int main()
{
   CSoundCard sc;
   int num = sc.GetSpec1();  // returns 1
   sc.SetSpec1(6); // sets m_nSpec1 to 6
   return 0;
}


Unfortunately, this won't make much sense unless you understand OOP and C++.

There are other languages that you can use, such as Java and C#.

Best of luck,
