Associative Arrays in C++ - Map(3C++)

Associative Arrays in C++ - Map(3C++)

An "associative array" is a one-dimensional array of unbounded size whose subscripts can be non-integral types such as character strings. Traditionally associated with dynamically typed languages such as AWK and SNOBOL4 , associative arrays have applications ranging from compiler symbol tables to databases and commercial data processing.

This section describes a family of C++ class definitions for associative arrays, including programming examples, application suggestions, and notes on performance. It concludes with a complete programming example which serves the same purpose as a well-known system command but is much smaller and simpler.
