ACCU, previously known as Association of C and C++ Users, is a non-profit user group of people interested in software development, dedicated to raising the standard of computer programming. The ACCU publishes two journals and organizes an annual conference.
ACCU was formed in 1987 by Martin Houston. The original name of the organisation was C Users' Group (UK) and this remained the formal name of the organisation until 2011, although it adopted the public name Association of C and C++ Users for the period 1993–2003, and adopted the shorter form ACCU from 2003 onward. As the formal name suggests, the organisation was originally created for people in the United Kingdom. However, the membership is worldwide, predominantly European and North American, but also with members from central and southern America, Australasia, Africa and Asia. Originally, the voluntary association was mainly for C programmers, but it has expanded over time to include all programming languages, especially C++, C#, Java, Perl and Python.
The ACCU currently publishes two journals:
Other journals have been published by ACCU in the past. Accent was the news letter of the Silicon Valley chapter and CAUGers was the news letter of the Acorn special interest group. Overload was originally the journal of ACCU's C++ special interest group, but is no longer language-specific.
