Quick Review

Always use parenthesis to disambiguate the precedence of operators if there is any question or opportunity for confusion.

The arithmetic operators all work like they do in normal mathematics. The Modulus (%) operator returns the remainder from an integer division. Beware about rounding or sign errors when the operands of integer division . . . → Read More: 3.x — Comprehensive Quiz

In addition to container classes and iterators, STL also provides a number of generic algorithms for working with the elements of the container classes. These allow you to do things like search, sort, insert, reorder, remove, and copy elements of the container class.

Note that algorithms are implemented as global functions that operate using . . . → Read More: 16.4 — STL algorithms overview

An Iterator is an object that can traverse (iterate over) a container class without the user having to know how the container is implemented. With many classes (particularly lists and the associative classes), iterators are the primary way elements of these classes are accessed.

An iterator is best visualized as a pointer to a . . . → Read More: 16.3 — STL iterators overview

By far the most commonly used functionality of the STL library are the STL container classes. If you need a quick refresher on container classes, check out lesson 10.4 — Container Classes.

The STL contains many different container classes that can be used in different situations. Generally speaking, the container classes fall into three . . . → Read More: 16.2 — STL containers overview
