Why prefix is faster than postfix

[Eliza sahoo]

Prefix operation is faster and better than to postfix operation.
Now let us see how both postfix and prefix work.

// postfix
iterator operator++(int)
{
iterator _Tmp = *this;
++*this;
return (_Tmp);
}

// prefix
iterator& operator++()
{
_Ptr = _Acc::_Next(_Ptr);
return (*this);
}
note: one integer dummy variable is used in postfix operation in order to distinguish weather it is a postfix operation or prefix operation. This dummy variable is never used.
(refer prefix / postfix overloading).

hope it would be helpful to all of you.
Any suggestions are appreciated.

Thanks

Note that this might be so for C++, but not necessarily for Java.
