Binary Arithmetic Operators Comparison Operator Assignment Operators Unary Operators
The following rules apply to all prefix unary operators. To declare a unary operator function as a non-static member function, use this declaration form:return-type operator op (); In this form, return-type is the return type and op is one of the operators listed in the preceding table....
where ret-type and op are as described for member operator functions and the arg is an argument of class type on which to operate.备注 There is no restriction on the return types of the unary operators. For example, it makes sense for logical NOT (!) to return an integral value, but ...
There is no restriction on the return types of the unary operators. For example, it makes sense for logical NOT (!) to return an integral value, but this is not enforced. 2.重载二元操作符 To declare a binary operator function as anonstatic member, you must declare it in the form: ret...
|| Logical OR Binary ~ One's complement Unary delete Delete — new New — conversion operators conversion operators Unary 1 Two versions of the unary increment and decrement operators exist: preincrement and postincrement. See General Rules for Operator Overloading for more information. The constra...
There are mainly three types of overloadable operators called unary, binary, and conversion. But not all operators of each type can be overloaded. Let us cover each type of operator in more detail below. Overloading Unary Operators Unary operators are those which require only a single ...
Learn how to overload a C# operator and which C# operators are overloadable. In general, the unary, arithmetic, equality and comparison operators are overloadable.

Unary operators: +, -, !, ~, ++, --, true, false Binary operators: +, -, *, /, %, &, |, ^, <<, >>, ==, !=, >, <, >=, <= The following code example creates a ComplexNumber class that overloads the + and - operators: ...
