Duplicate code

[1] A minimum requirement is usually applied to the quantity of code that must appear in a sequence for it to be considered duplicate rather than coincidentally similar.

This may lead to shorter compilation times, lower cognitive load, less human error, and fewer forgotten or overlooked pieces of code.

[4] Clones may be the most effective solution if the programming language provides inadequate or overly complex abstractions, particularly if supported with user interface techniques such as simultaneous editing.

[5] A study by Wagner, Abdulkhaleq, and Kaya concluded that while additional work must be done to keep duplicates in sync, if the programmers involved are aware of the duplicate code there weren't significantly more faults caused than in unduplicated code.

Using the above function will give source code that has no loop duplication: Note that in this trivial case, the compiler may choose to inline both calls to the function, such that the resulting machine code is identical for both the duplicated and non-duplicated examples above.
