The overloads of operators & and || lose short-circuit evaluation.

The overload of operator -> must either return a raw pointer, or return an object (by reference or by value) for which operator -> is in turn overloaded.

It is not possible to change the precedence, grouping, or number of operands of operators.

operator + = ( "world" ) // same as str += "world" Overloaded operators (but not the built-in operators) can be called using function notation: Note: for overloading co_await, (since C++20) user-defined conversion functions, user-defined literals, allocation and deallocation see their respective articles.

In this table, is a placeholder representing all matching operators: all prefix operators in all postfix operators other than -> in all infix operators other than = in addition, for comparison operators =, ! =,, =,, overload resolution also considers the rewritten candidates generated from operator = or operator. Given std:: vector :: iterator i, i ++ calls i. Given std:: unique_ptr p, p - >bar ( ) calls p.

When an operator appears in an expression, and at least one of its operands has a class type or an enumeration type, then overload resolution is used to determine the user-defined function to be called among all the functions whose signatures match the following: 6) overloaded co_await operator for use in co_await expressions.
