Operators

Operators are special symbols or keywords that perform operations on one or more operands (variables, literals, expressions).

Operator	Name	Example	Result	Notes
`+`	Addition	`5 + 3`	8	Also string concatenation
`-`	Subtraction	`10 - 4`	6	Unary minus: `-x`
`*`	Multiplication	`6 * 7`	42	—
`/`	Division	`10 / 3`	3	Integer division truncates toward zero
`%`	Modulus	`10 % 3`	1	Remainder

Compound assignment (shorthand): += -= *= /= %=

Operator	Meaning	Example	Result
`==`	Equal	`5 == 5`	`true`
`!=`	Not equal	`5 != 3`	`true`
`<`	Less than	`4 < 10`	`true`
`>`	Greater than	`15 > 7`	`true`
`<=`	Less than or equal	`5 <= 5`	`true`
`>=`	Greater than or equal	`8 >= 10`	`false`

Operator	Name	Example	Result when...	Short-circuit?
`&&`	AND	`true && false`	`true` only if both are true	Yes
`		`	OR	`true
`!`	NOT	`!true`	Reverses the value	—

Example combining operators

int a = 17, b = 5;
bool isBig = a > 10 && (a % 2 == 1);          // true
bool safeDivide = b != 0 && (a / b > 3);      // short-circuit prevents /0
