Short for reproduce. When testing the game, defects are typically logged into a database system. Bugs are then repro'ed (reproduced) according to directions left in the database to help the software engineer(s) locate and correct the defect.


Software Development Kit.


an algorithm used to sort elements in an array. Developed by C.A.R. Hoare, it has an average efficency of 1.4n log2(n) as compared to Insertion, Selection, and Bubble with averages of n(n-1)/4, n(n-1)/2, and

A program that executes programs. Different from a compiler which turns a source code into an executable, the interperter will run interpret-compile each command while running.


a collection of data and routines that act on the data. It might also be a collection of routines that provides a cohesive set of services even if no common data is involved. Examples include a source file in C, a class in C++, a package in Ada, and a unit in some versions of Pascal.
