Program comprehension (also program understanding or [source] code comprehension) is a domain of computer science concerned with the ways software engineers maintain existing source code. The cognitive and other processes involved are identified and studied.cite-ref-1[1] The results are used to develop tools and training.cite-ref-2[2]

Software maintenance tasks have five categories: adaptive maintenance, corrective maintenance, perfective maintenance, code reuse, and code leverage.
