What are the 3 logical operators?
There are three logical operators: and , or , and not . The semantics (meaning) of these operators is similar to their meaning in English. For example, x > 0 and x < 10 is true only if x is greater than 0 and at the same time, x is less than 10.
What are the 2 logical operators?
Common logical operators include AND, OR, and NOT.
What are logical operators give an example?
Logical Operators
Operator | Name | Example result |
---|---|---|
&& | AND. True only if both operands are true. | 0 (only one is true) |
|| | OR. True if either operand is true. | 1 (the first test is true) |
∼ | NOT. Changes true to false and false to true. | 1 (the strings are not equal) |

How do you use logical operators?
You use the logical operators to combine two Boolean values and return a true, false, or null result. Logical operators are also referred to as Boolean operators. Returns True when Expr1 and Expr2 are true. Returns True when either Expr1 or Expr2 is true.
What is the use of logical operator?
Logical Operators are used to perform logical operations and include AND, OR, or NOT. Boolean Operators include AND, OR, XOR, or NOT and can have one of two values, true or false.

Which operation replaces the lowest bit that is 1 with 0?
2 Answers. n & ~1 replaces the least significant bit of n with zero; n | 1 , with one. To replace the LSB with b , where b can be either 0 or 1, you can use (n & ~1) | b .
