Basic C Programming - Logical Operators

What is the result of the logical AND operator (&&) if both operands are true?

• null

• false

• true

• 0

What is the result of the logical OR operator (||) if one of the operands is true?

• undefined

• null

• true

• false

What is the result of the logical NOT operator (!) if the operand is true?

• null

• undefined

• false

• true

What is short-circuiting in logical operators?

• Short-circuiting in logical operators is when the evaluation of the second operand is skipped if the outcome can be determined by evaluating the first operand alone.

• Short-circuiting is when both operands are evaluated regardless of the outcome

• Short-circuiting means the logical operator is not applied

• Short-circuiting only applies to bitwise operators

How many operands does the logical NOT operator (!) take?

• 1

• 3

• 4

• 2

What is the precedence of logical AND operator (&&) compared to logical OR operator (||)?

• && has lower precedence than ||

• && and || have the same precedence

• || has higher precedence than &&

• && has higher precedence than ||

Can logical operators be used with non-boolean data types in C?

• Sometimes

• Maybe

• Yes

• No

What is the result of the expression (5 > 3 && 2 < 4)?
