What is or?

OR is a logical operator often used in programming, mathematics, and digital circuits. It returns true if at least one of its operands is true. In programming, OR is used in conditional statements to execute a block of code if one or more conditions are met.

Here's a breakdown:

• Logical OR: The basic concept of <a href="https://www.wikiwhat.page/kavramlar/Logical%20OR">Logical OR</a>. If either A or B or both are true, then A OR B is true.

• Truth Table: The truth table visually represents the results of the OR operation.

  A	B	A OR B
  True	True	True
  True	False	True
  False	True	True
  False	False	False

• Programming Languages: Most programming languages implement the OR operator using symbols like || (e.g., C++, Java, JavaScript, Python) or the keyword or (e.g., Python). It is a fundamental aspect of <a href="https://www.wikiwhat.page/kavramlar/Conditional%20Statements">Conditional Statements</a>.

• Short-circuiting: In many languages, the OR operator exhibits <a href="https://www.wikiwhat.page/kavramlar/Short-circuiting">short-circuiting</a> behavior. This means that if the first operand is true, the second operand is not evaluated, as the result is already known to be true. This can improve performance and prevent errors.

• Bitwise OR: In some contexts, particularly when working with binary data, a <a href="https://www.wikiwhat.page/kavramlar/Bitwise%20OR">Bitwise OR</a> operation is used. This applies the OR operation to each corresponding bit of the operands.
