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.... see more ›
There are five logical operator symbols: tilde, dot, wedge, horseshoe, and triple bar. Tilde is the symbol for negation.... see more ›
Digital logic has three basic operators, the AND, the OR and the NOT. These three operators form the basis for everything in digital logic. In fact, almost everything your computer does can be described in terms of these three operations.... see more ›

For example, IF A is true AND B is true AND C is true AND D is true, THEN Z is true. Otherwise, Z is false. It is a simple matter to perform the basic operations using ordinary manually operated switches, with a lamp to indicate the logical outcome. This is how we perform the AND operation on A,B,C and D.... see more ›
If a sentence has only one logical operator, then that is the main operator. If a sentence has more than one logical operator, then the main operator is the one outside the parentheses. If a sentence has two logical operators outside the parentheses, then the main operator is not the negation.... read more ›
The logical OR ( || ) operator (logical disjunction) for a set of operands is true if and only if one or more of its operands is true. It is typically used with boolean (logical) values. When it is, it returns a Boolean value.... continue reading ›
There are seven basic logic gates: AND, OR, XOR, NOT, NAND, NOR, and XNOR. The AND gate is so named because, if 0 is called "false" and 1 is called "true," the gate acts in the same way as the logical "and" operator.... see more ›
|&& (Logical AND)||This operator returns true if all relational statements combined with && are true, else it returns false.|
||| (Logical OR)||This operator returns true if at least one of the relational statements combined with || is true, else it returns false.|
Since the late 1960's 'the rules of structure' and been supported by structured programming languages with language elements to support the three 'original' logical structures: Sequence, Alternative Selection, and Loops.... read more ›
Definitions of Logic
“The study of truths based completely on the meanings of the terms they contain.” Logic is a process for making a conclusion and a tool you can use. The foundation of a logical argument is its proposition, or statement. The proposition is either accurate (true) or not accurate (false).... view details ›

The definition of logic is a science that studies the principles of correct reasoning. An example of logic is deducing that two truths imply a third truth. An example of logic is the process of coming to the conclusion of who stole a cookie based on who was in the room at the time.... see more ›

There are two common types of operations: unary and binary. Unary operations involve only one value, such as negation and trigonometric functions. Binary operations, on the other hand, take two values, and include addition, subtraction, multiplication, division, and exponentiation.... read more ›

The reserved values must be preceded and followed by blanks. The operands in a logical expression consist of relational expressions or logical variables or constants separated by logical operators. The *AND operator indicates that both operands (on either side of the operator) have to be true to produce a true result.... view details ›
A simple statement is one that does not contain another statement as a component. These statements are represented by capital letters A-Z. A compound statement contains at least one simple statement as a component, along with a logical operator, or connectives.... see more ›
Logical operators are very important in any programming language and they help us take decisions based on certain conditions. Suppose we want to combine the result of two conditions, then logical AND and OR logical operators help us in producing the final result. Called Logical AND operator.... view details ›
In logic, mathematics and linguistics, And ( ) is the truth-functional operator of logical conjunction; the and of a set of operands is true if and only if all of its operands are true. The logical connective that represents this operator is typically written as. or ⋅ . Logical conjunction.... see more ›
Arithmetic operator are of two types:Unary Operators: Operators that operates or works with a single operand are unary operators. Logical Operators: Logical Operators are used to combine two or more conditions/constraints or to complement the evaluation of the original condition in consideration.... view details ›
Operators perform mathematical, string, and logical operations on values. Operands are expressions on which operations are performed. BASIC operators are divided into the following categories: Arithmetic.... read more ›
Boolean Logic is a form of algebra which is centered around three simple words known as Boolean Operators: “Or,” “And,” and “Not”. At the heart of Boolean Logic is the idea that all values are either true or false.... see more ›

Logical structure refers to the way information in a document is organized; it defines the hierarchy of information and the relation between different parts of the document. Logical structure indicates how a document is built, as opposed to what a document contains.... see more ›
Also called a decision, one of the three basic logic structures in computer programming. The other two logic structures are sequence and loop. In a selection structure, a question is asked, and depending on the answer, the program takes one of two courses of action, after which the program moves on to the next event.... see details ›
