Logical operators are
used to evaluate two or more conditions
. ... The AND ( && ) and OR ( || ) are binary operator while NOT ( ! ) is a unary operator. Before we start explaining && operator, keep in mind that – In C, all non-zero values are considered as true ( 1 ) while 0 is considered as false.
What is logical operator in C with example?

Operator Description Example
|
&& Called Logical AND operator. If both the operands are non-zero, then the condition becomes true. (A && B) is false.
|
|| Called Logical OR Operator. If any of the two operands is non-zero, then the condition becomes true. (A || B) is true.

Which are logical operators?
A logical operator is
a symbol or word used to connect two or more expressions such
that the value of the compound expression produced depends only on that of the original expressions and on the meaning of the operator. Common logical operators include AND, OR, and NOT.
What are 3 logical operators explain in detail?
1-Evaluates operands from left to right. 2-For each operand converts it to boolean. If the result is true, stops and returns the original value of that operand. 3-
If all operands have been evaluated (i.e. all were false), returns the last operand.

Which is not a logical operator?
The NOT logical operator reverses the true/false outcome of the expression that immediately follows. ... You can substitute
~ or ¬

What is logical operator example?
For example,
a && b returns
true when both a and b are true (i.e. non-zero). Logical OR operator: The ‘||’ operator returns true even if one (or both) of the conditions under consideration is satisfied. Otherwise it returns false. For example, a || b returns true if one of a or b or both are true (i.e. non-zero).

values and provide a single boolean output. The operators include: && , || , and ! .
What is the symbol of logical operators?
The logical operator *NOT is used to negate logical variables or constants. *AND and *OR are the reserved values used to specify the relationship between operands in a logical expression. The ampersand symbol

Logic operations include
any operations that manipulate Boolean values
. Boolean values are either true or false. ... All Boolean functions can be built from these three basic operators. Given two Boolean variables A and B, the Boolean expression A ^ B is true only if both A and B are true.

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.
What are the two results of logical operators?
Logical expressions, like comparison expressions, return a true (1) or false (0) value when processed. Logical operators combine
two comparisons and return the true (1) or false (0) value
depending on the results of the comparisons.
