operator = must be overload as a member function NOTE2: An operator function must either be a member of a class or have at least one parameter ofclass type. //操作符重载,有一个最基本条件,就是一定有一个一元是一个自定义的C++类 //如果两个都是
with C++ programming language. Operator overloading adds new functionality to its existing operators. The programmer must add proper comments concerning the new functionality of the overloaded operator. The program will be efficient and readable only if operator overloading is used only when necessary...
No, an overloaded binary operator must be a standalone non-member function taking two parameters, or a non-static member function taking one parameter. It cannot be a static member function. Igor Tandetnik Monday, October 6, 2014 1:24 PM On 10/3/2014 10:11 AM, webJose wrote: As...
To declare a binary operator function as aglobal function, you must declare it in the form: ret-typeoperatorop(arg1,arg2) whereret-typeandopare as described for member operator functions andarg1andarg2are arguments.At least one of the arguments must be of class type. There is no restriction...
In addition, overload operators must use the defined operator name. The only exception is when you create aconversion operator, where the operator name matches the return type of the conversion. Duplicate overloads defined CS0111-Type already defines a member called 'name' with the same paramete...
You have the wrong number of parameters in the operator definition. In addition, overload operators must use the defined operator name. The only exception is when you create a conversion operator, where the operator name matches the return type of the conversion. Duplicate overloads defined CS...

define the operator in such a way that either an argument to it or the return type from it (or both) is the same type as the class that defines it. Your overloaded operators must furthermore use the "Return" keyword to return their results, and they do not support an "Exit" ...
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 operand/parameter for the operation. The class or struct involved in the operation must contain ...
