Understanding the common Boolean operators

Cards (50)

  • What are Boolean operators used for?
    Logical operations
  • How are Boolean operators applied in programming examples?
    Decision-making
  • Under what condition does the AND operator return true?
    Both operands are true
  • Match the Boolean operator with its definition:
    AND ↔️ Returns true if both operands are true
    OR ↔️ Returns true if at least one operand is true
    NOT ↔️ Negates the operand
  • What is the truth table output for the AND operator when both operands are false?
    False
  • The AND operator is commonly used in `if` statements to check multiple conditions.
    True
  • The AND operator returns true only if both operands are true.
  • Under what condition does the OR operator return false?
    Both operands are false
  • The three common Boolean operators are AND, OR, and NOT
  • What is the result of the AND operator when one operand is true and the other is false?
    False
  • The NOT operator returns true only if the input is false

    True
  • A truth table is a tool for understanding how Boolean operators behave
  • What Boolean operator returns true if at least one operand is true?
    OR
  • Which Boolean operator negates the operand?
    NOT
  • What does the OR operator check in the example `if (isWeekend OR isHoliday)`?
    Weekend or holiday
  • The NOT operator returns true if the input value is false
  • In PEMDAS/BODMAS, the NOT operator has higher precedence than the OR
  • The three common Boolean operators are AND, OR, and NOT
  • Evaluating complex Boolean expressions requires understanding the precedence of operators.
  • The OR operator returns true if at least one operand is true.

    True
  • Order the steps to evaluate a complex Boolean expression:
    1️⃣ Identify the operators
    2️⃣ Apply precedence rules
    3️⃣ Evaluate individual operators
    4️⃣ Simplify the expression
  • The OR operator returns false only when both operands are false.
  • Match the Boolean operator with its symbol in programming:
    AND ↔️ &&
    OR ↔️ ||
    NOT ↔️ !
  • The OR operator always returns true if at least one operand is true.
    True
  • Boolean operators are used to control program flow in loops and conditions.

    True
  • What is the definition of the AND operator?
    Both operands must be true
  • The NOT operator negates the operand, returning the opposite Boolean value
  • What is the primary use of Boolean operators in programming?
    To make decisions
  • What is the output of the NOT operator when the input is true?
    False
  • Boolean operators work with Boolean values (true or false).

    True
  • The NOT operator changes true to false and false to true.
    True
  • The expression `NOT isEnrolled` will return true if isEnrolled is false.
    True
  • Order the steps to evaluate complex Boolean expressions according to PEMDAS/BODMAS
    1️⃣ Evaluate parentheses
    2️⃣ Evaluate NOT
    3️⃣ Evaluate AND
    4️⃣ Evaluate OR
  • The expression `(a > 10 && b < 20) || c == 30` evaluates to true if a = 15, b = 15, and c = 30.

    True
  • Truth tables demonstrate how Boolean operators behave with different inputs.

    True
  • What are Boolean operators defined as?
    Logical operators
  • What does the NOT operator do to a Boolean value?
    Negates the value
  • Boolean operators are used in programming to make decisions based on conditions.
    True
  • What is the output of NOT applied to true?
    False
  • What type of values do Boolean operators work with?
    True or false
