One may recognize the typical subdivision into two blocks: First the public
block is declared with a constructor, a destructor, arithmetic operators, and
member functions as well as the friend functions of the class. A short block of
private data elements is joined to the public interface, identified by the label
private
. It is an aid to clarity and is considered good style to place the public
interface before the private block and to use the labels “public” and “private” only
once each within a class declaration.
The list of operators appearing in the section of the class declaration shown
here is by no means complete. It is missing some arithmetic functions that cannot
be represented as operators as well as most of the number-theoretic functions,
which we know already as C functions. Furthermore, the announced constructors
are as little represented as the functions for input and output of
LINT
objects.
In the following parameter lists of the operators and functions the address
operator
&
appears, which has the effect that objects of the class
LINT
are passed
