Difference between Unary and Binary Operators Last Updated : 20 Mar, 2024 Comments Improve Suggest changes Like Article Like Report Unary Operators and Binary operators are both fundamental concepts in computer science and programming languages, especially in the context of arithmetic and logical operations. Here's a breakdown of the differences between them: Unary Operators:Unary Operator is an operator that operates on a single operand, meaning it affects only one value or variable. Unary operators are commonly used in programming languages to perform various operations such as changing the sign of a value, incrementing or decrementing a value, or performing logical negation. Examples of Unary Operators:Here are the examples of Unary Operator in Programming: Unary minus (-x)Increment (++)Decrement (--)Logical NOT (!x)Binary Operators:Binary Operator is an operator that operates on two operands, meaning it affects two values or variables. Binary operators are commonly used in programming languages to perform various operations such as arithmetic operations, logical operations, and bitwise operations. Examples of Binary Operators:Here are the examples of Binary operator in Programming: Addition (+)Subtraction (-)Multiplication (*)Division (/)Assignment (=)Logical AND (&&)Logical OR (||)Difference between Unary and Binary Operators:AspectUnary OperatorsBinary OperatorsNumber of OperandsOperates on one operandOperates on two operandsExample-x, ++i, !flagx + y, a * b, value == 10OperationsTypically perform operations on a single valuePerform operations involving two valuesSyntax and UsageMay appear before or after the operandAppears between the operandsPurposeUsed for operations like negation, increment, etc.Used for arithmetic operations, comparisons, etc.AssociativitySome have prefix and postfix forms (++i, i++)Usually left-associative (a + b + c) Comment More infoAdvertise with us Next Article Difference between Unary and Binary Operators S srinam Follow Improve Article Tags : C Language Similar Reads What is the Difference Between XOR and XNOR Gate? In electronics, Logic Gates are termed as “building blocks of digital circuitsâ€. These gates are used to perform logical operations on single or multiple binary values. In the term “Logic Gateâ€, a Gate represents a circuit that controls the incoming electric signals.

A Bitwise And operator is represented as '&' and a logical operator is represented as '&&'. The following are some basic differences between the two operators. a) The logical and operator '&&' expects its operands to be boolean expressions (either 1 or 0) and returns a boolean va 4 min read Difference between Operator Precedence and Operator Associativity In programming, operators are used to perform various operations on data. Understanding how operators interact with each other is crucial for writing correct and efficient code. In this article, we will explore the two most important concepts which are Operator Precedence and Operator Associativity. 3 min read What is the difference between = (Assignment) and == (Equal to) operators = operator The "=" is an assignment operator used to assign the value on the right to the variable on the left. For example: a = 10; b = 20; ch = 'y'; Example: C // C program to demonstrate // working of Assignment operators #include <stdio.h> int main() { // Assigning value 10 to a // using 2 min read Increment and Decrement Operators in Programming Increment and Decrement Operators are Unary Operators commonly used in programming to increase or decrease the value of a variable by one, respectively. They provide a shorthand way to perform these common operations.

It is used to check the equality of both operands, however, the type of the operands does not match. For instance, an integer type variable is equivalent to the floating point number if the value of both the operands is same. It is a binary 2 min read Unary Operators in C In C programming, unary operators are operators that operate on a single operand. These operators are used to perform operations such as negation, incrementing or decrementing a variable, or checking the size of a variable. They provide a way to modify or manipulate the value of a single variable in 5 min read Unary Operators In C++ In C++, unary operators are the type of operators that work on a single value (operand). They perform operations like changing a value's sign, incrementing or decrementing it by one, or obtaining its address.C++ has a total of 9 unary operators:Table of ContentIncrement Operator (++)Decrement Operat 6 min read Binary Operators in Programming Binary Operators are essential tools in programming that perform operations on pairs of data, enabling tasks like calculations, comparisons, logical operations, and bitwise manipulations.
