Class structure (Newbie)

[sam]

Hi,
See this example of class:-
class a{
private:
int o,t;
public:
a( ) { };
a(int s,int g)
{o=s;
t=g;
}
};
My question is see o=s; and t=g;
What we are doing this we are inserting the public value to private
value or converting public to private.I new to c++ programming but I
want to understand the logic behind this or the technique behind
this(Simply I curious about how this work? )
Thanks for advance.

'public' and 'private' refer to class members. s and g are not class
members, they are input parameters from the world outside the class.

The compiler simply refuses to compile anything that accesses those
variables directly.

You are not 'inserting' but copying value of s and g into o and t
respectively. o and t will continue to remain private.

a(int s, intg) is a constructor for your class a. It takes two interger
paramters passed by value, then assigns these values to the class's private
variables o and t. The class itself can use it's own private variables in
it's own methods (including constructor).

Incidently, the same thing can be achieved by:

a( const int s, const int g): o(s), t(g) {};

which basically does the same thing except it initializes o and t to the
values instead of assigns them.
