You don't need pointers to multiply two matrixes; pointers to something are the address in memory of that something.

kind regards,

Pointers aren't that hard. You already know how to use them.
For example, let's say your house is located at 123 Fox Street. Now suppose you want to identify the kitchen in the house. In C/C++ that looks like:

house.kitchen

Or using the address of your house rather than trhe house itself:

123 Fox Street ->kitchen

Of course you need variables for the house and one for the address:

struct House
{
    struct kitchen
    {

    };
};

House house;
House* ptr;

and before you can use the pointer you need to put the address of the house in it:

ptr = &house;

and off you go.

By changing the address in ptr you can reuse the using ptr for different houses.

Lastly, if you know the address of the house, then you can refer to the house directly by de-referencing the pointer:

(*ptr).kitchen                /*same as house.kitchen */

and that's about it.
