Binary Arithmetic Operators Comparison Operator Assignment Operators Unary Operators
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 ...
In this form,return-typeis the return type andopis one of the operators listed in the preceding table. To declare a unary operator function as a nonmember function, use this declaration form: return-typeoperatorop(class-type); In this form,return-typeis the return type,opis one of the ope...
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...
The postfix increment and decrement operators (++ and ––) are treated separately in Increment and Decrement. Conversion operators are also discussed in a separate topic; see Conversions. The following rules are true of all other unary operators. To declare a unary operator function as a nonstat...

The overloadable unary operators and the corresponding operator strings are the following: For example, the++operator forDurationcan be defined like this: structDuration{intminute;refDurationopUnary(stringop)()if(op=="++"){++minute;returnthis;}} ...
