Cheating is defined as dishonest or unfair behavior, typically in a situation where one is expected to play by certain rules. It can involve breaking established rules or guidelines, either intentionally or unintentionally, with an aim to gain advantage over others. Cheating can take many forms such as plagiarizing someone else's work, copying another person's answers during a test, or taking shortcuts that compromise the quality of one’s output. It is often considered as a negative behavior and can result in consequences ranging from losing points to expulsion depending on the severity of the act.
