Operators in C Programming

Operators in C

1. Arithmetic Operators

• Addition (+): Adds two operands.
• Subtraction (-): Subtracts the right operand from the left.
• Multiplication (*): Multiplies two operands.
• Division (/): Divides the left operand by the right (integer division if both are integers).
• Modulus (%): Returns the remainder of the division of two integers.

2. Relational Operators

• Equal to (==): Checks if two operands are equal.
• Not equal to (!=): Checks if two operands are not equal.
• Greater than (>): Checks if the left operand is greater than the right.
• Less than (<): Checks if the left operand is less than the right.
• Greater than or equal to (>=): Checks if the left operand is greater than or equal to the right.
• Less than or equal to (<=): Checks if the left operand is less than or equal to the right.

3. Logical Operators

• Logical AND (&&): Returns true if both operands are true.
• Logical OR (||): Returns true if at least one operand is true.
• Logical NOT (!): Inverts the truth value of the operand.

4. Bitwise Operators

• Bitwise AND (&): Compares each bit of two operands and returns 1 if both bits are 1.
• Bitwise OR (|): Compares each bit and returns 1 if at least one bit is 1.
• Bitwise XOR (^): Compares each bit and returns 1 if the bits are different.
• Bitwise NOT (~): Flips all the bits in the operand.
• Left Shift (<<): Shifts bits to the left, filling with zeros.
• Right Shift (>>): Shifts bits to the right.

5. Assignment Operators

• Assignment (=): Assigns the value of the right operand to the left operand.
• Add and assign (+=): Adds right operand to left operand and assigns the result.
• Subtract and assign (-=): Subtracts right operand from left operand and assigns the result.
• Multiply and assign (*=): Multiplies left operand by right operand and assigns the result.
• Divide and assign (/=): Divides left operand by right operand and assigns the result.
• Modulus and assign (%=): Applies modulus operator and assigns the result.

6. Increment and Decrement Operators

• Increment (++): Increases the value of the operand by 1. Can be prefix (++a) or postfix (a++).
• Decrement (--): Decreases the value of the operand by 1. Can be prefix (--a) or postfix (a--).

7. Conditional (Ternary) Operator

• Ternary (? :): A shorthand for if-else. Syntax: condition ? expression_if_true : expression_if_false.

8. Comma Operator

• Comma (,): Evaluates two expressions and returns the value of the second expression.

9. Sizeof Operator

• Sizeof: Returns the size (in bytes) of a data type or variable.

10. Pointer Operators

• Address-of (&): Returns the memory address of a variable.
• Dereference (*): Accesses the value at the address specified by a pointer.

Each operator serves a specific role in C programming, enabling a wide variety of operations and manipulations to be performed on data. Understanding these operators is crucial for effective programming in C.

Arithmetic Operators

• Addition (+), Subtraction (-), Multiplication (*) perform standard mathematical operations.
• Division (/) performs integer division if both operands are integers, meaning it only returns the whole number part of the result.
• Modulus (%) returns the remainder after integer division.

Relational Operators

• Equal to (==) and Not equal to (!=) compare if two operands are the same or different.
• Greater than (>), Less than (<), Greater than or equal to (>=), and Less than or equal to (<=) compare the values of two operands.
