destructiveand
DestructiveAND is a term used in computer science and digital logic to describe a bitwise logical AND operation that overwrites one of its operands with the result, thereby destroying the original value of that operand. The operation is performed in‑place, often to conserve memory or to improve performance by avoiding the allocation of a separate result variable.
The concept arises frequently in low‑level programming, especially in assembly languages such as x86, ARM, and
DestructiveAND is useful in situations where the intermediate result will not be needed, for example in cryptographic
The term is also used informally in documentation and discussions of parallel computing to emphasize the destructive
Related concepts include bitwise OR, XOR, and logical NOT, each of which can also be performed destructively
