Cheatsheet: Operators

Your everyday family of operators.

Arithmetic

+ - * / % (% is modulo)

Assignment

• = basic
• += add-and-assign
• *= multiply-and-assign

Comparison

• == equals
• != not equals
• < > <= >=

Logical

• && AND
• || OR
• ! NOT

Bitwise

• & AND | OR ^ XOR ~ NOT
• << left shift >> right shift

Address

• & address-of
• * dereference
• -> struct member via pointer

TL;DR

• == for equality, = for assignment.
• && and || combine conditions.
• % is modulo.
• & gets addresses; * dereferences.
