Understanding C# Operators: Precedence, Associativity, and Operator Types

Learn about the different types of operators in C# (arithmetic, logical, bitwise, etc.), their precedence, and associativity. This tutorial provides a comprehensive guide to C# operators, essential knowledge for writing correct and efficient C# code.

Operators in C#

Operators are symbols that perform operations on one or more operands (values or variables). C# supports various types of operators for different operations (arithmetic, logical, bitwise, etc.). Understanding operator precedence and associativity is crucial for writing correct code.

Types of Operators in C#

• Arithmetic Operators: Perform arithmetic calculations (`+`, `-`, `*`, `/`, `%`).
• Relational Operators: Compare values (`<`, `>`, `<=`, `>=`, `==`, `!=`).
• Logical Operators: Combine boolean expressions (`&&`, `||`, `!`).
• Bitwise Operators: Perform bitwise operations (`&`, `|`, `^`, `~`, `<<`, `>>`).
• Assignment Operators: Assign values (`=`, `+=`, `-=`, etc.).
• Unary Operators: Operate on a single operand (`+`, `-`, `++`, `--`, `!`).
• Ternary Operator: A conditional operator (`?:`).
• Other Operators: Includes `as`, `is`, `typeof`, `nameof`, etc.

Operator Precedence and Associativity

Operator precedence determines the order of operations. For example, multiplication and division have higher precedence than addition and subtraction. Associativity specifies the direction of evaluation (left-to-right or right-to-left).

Example: `10 + 5 * 5` evaluates to 35 because multiplication is performed before addition.
