(C++) operator

Definition: A conventional notation for built-in operation, such as +, *, and & [1].

Also a keyword used for operator overloading. Preserve natural semantics for overloaded operators [2]. Consider overloading to avoid implicit type conversions [3].

List of overloadable operators:

• &, bitwise and operator
• |, bitwise or operator
• ^, bitwise xor operator
• ~, bitwise not operator
• ,, comma operator
• --, decrement operator
• delete
• delete[]
• /, divide operator
• /=, divide assign operator
• =, assign operator
• ==, equal operator
• >, greater than operator
• >=, greater than or equal operator
• ++, increment operator
• <, less than operator
• <=, less than or equal operator
• &&, logical and operator
• ||, logical or operator
• ., member access operator
• .*
• ->, member access operator
• ->*
• -, minus operator
• -=
• %, modulus operator
• *, multiply operator
• *=, multiply assign operator
• new operator
•  ?new[] operator
• !=, not equal operator
• +, plus operator
• +=, plus assign operator
• ::, scope operator
• ?:, questionmark colon operator
• [], index operator
