Copy Constructor

While we create a copy constructor Is this code coreect or wrong?
class a
{
public:
a(a &b)
{}
}

It should be like ::

class a
{
public:
a(const a &b)
{}
}

This is absolutely correct. const is required to prevent the passing object being changed by copy constructor code.

i think its working. i will say tomorrow how it works

Copy constructor can be like this

B(const B &b)
{
//initialization
}

ur code is absolutely correct

that code is correct,but if u create a constant object then dt code is not correct,u have to write const classname&,like dt.ok,,,,,,,if u do not write const object then dt code is ok.

What ever u have written that is absolutely correct...
