Glossary Glossary
- instance.
An example from a category. My cat is an instance of the category “feline things.” Every object is an instance of some type.
- instance variable.
One of the named data items that make up an structure. Each structure has its own copy of the instance variables for its type.
- constant reference parameter.
A parameter that is passed by reference but that cannot be modified.
- pure function.
A function whose result depends only on its parameters, and that has so effects other than returning a value.
- functional programming style.
A style of program design in which the majority of functions are pure.
- modifier.
A function that changes one or more of the objects it receives as parameters, and usually returns
void.
- fill-in function.
A function that takes an “empty” object as a parameter and fills in its instance variables instead of generating a return value.
- algorithm.
A set of instructions for solving a class of problems by a mechanical, unintelligent process.
