C++ Define Matrix

Hey ; )

I must use the logic of object-oriented programming.
How can i define a [3x3] matrix with use Class?

Can you give me advices or some examples? , thank you ; )

I am sorry, my english is not good so much. : p

What have you tried?

#include<iostream>
#include<conio.h>
using namespace std;

class matrix
{

public:
int a[3][3];

Can it be a matrix define with class?

I want to addition and multiplication calculation with use class ? I will use for it overloading technique. ; )

Use code tags when posting code.

Code:

#include<iostream>
#include<conio.h>
using namespace std;
 
class matrix
{
 
    public:
    int a[3][3];

First, you do not want to use using's in a header. Second, what is your problem with the implementation you posted?
