How to define operators in c language

Operators in C language are defined as operands performing operations under the action of specific operators. The classification includes arithmetic, relational, logical, bitwise operators, assignment operators and special operators.

Definition of operators in C language

In C language, operators are symbols or symbols that represent specific operations. Keywords used to perform various operations. The definition of operators is as follows:

Syntax:

<code class="c">运算符运算数(s)</code>

Among them:

• Operator: A kind of pre- A defined symbol or keyword that represents a specific operation.
• Operand: The object the operator acts on can be a variable, constant or expression.

Classification:

Operators in C language can be divided into the following categories according to their functions:

• Arithmetic operators: Perform arithmetic operations such as addition, subtraction, multiplication and division.
• Relational operators: Compares two values ​​for size or equality.
• Logical operators: Perform logical operations, such as AND, OR, NOT.
• Bit operators: Perform operations at the binary bit level.
• Assignment operator: Assigns a value to a variable.
• Special operators: Perform special operations such as taking address (&), dereferencing (*) and member access (.).

Definition example:

• Addition operator ( ): Adds two values.
• Equality relational operator (==): Compares two values ​​for equality.
• AND logical operator (&&): Returns true if both conditions are true.
• Assignment operator (=): assigns a value to a variable.
• Bracket operator (): Change the order of evaluation of expressions.

Note: The precedence of

• operators determines the order in which they are executed in an expression.
• Some operators require specific operand types. The syntax and semantics of
• operators may vary between different programming languages.
