Operators in C

Operators are symbols used to perform operations on operands (values or variables). C provides a wide range of operators for arithmetic, logical, relational, bitwise, and other operations.

Arithmetic Operators:

• +: Addition
• -: Subtraction
• *: Multiplication
• /: Division
• %: Modulus (remainder)

Example:

int x = 10;
int y = 5;

int sum = x + y;
int difference = x - y;
int product = x * y;
int quotient = x / y;
int remainder = x % y;

Relational Operators:

• ==: Equal to
• !=: Not equal to
• <: Less than
• >: Greater than
• <=: Less than or equal to
• >=: Greater than or equal to

Example:   

int age = 25;

if (age >= 18) {
    printf("You are an adult.\n");
}

Logical Operators:

• &&: Logical AND
• ||: Logical OR
• !: Logical NOT

Example:

int x = 10;
int y = 5;

if (x > 0 && y > 0) {
    printf("Both x and y are positive.\n");
}

Bitwise Operators:

• &: Bitwise AND
• |: Bitwise OR
• ^: Bitwise XOR
• ~: Bitwise NOT
• <<: Left shift
• >>: Right shift

Example:

int a = 5; // 0000 0101
int b = 3; // 0000 0011

int result = a & b; // 0000 0001

Other Operators:

• ?:: Ternary operator (conditional expression)
• sizeof: Sizeof operator (returns the size of a data type or variable)
• *: Dereference operator (used with pointers)
• &: Address-of operator (used to get the address of a variable)
• ->: Member access operator (used with structures and unions)
