===Etymology===
Introduced by the [[w:B (programming language)|B programming language]], which used the symbol "[[=]]" for [[variable]] [[assignment]]. The reasoning given by the creators of the language is that assignment is more frequent than equality testing, and thus deserves the shorter operator. The syntax was inherited by its successor [[w:C (programming language)|C]], and later adopted more widely. See [[wikipedia:Relational operator#Confusion with assignment operators]].
