允许定义多个操作符,根据参数类型不同匹配不同的操作符:例如+操作符可以匹配String、Int,只需要定义对应的plus 即可 子类的操作符允许通过override进行重载,重新定义操作符 get操作符则是通过[]来实现的 例如下方ElementOperator定义了get、minus、plus三个操作符,在main函数中对element对象进行-、[]、+的操作,对应着...

Learn: How to overload pre-decrement operator by using the concept of nameless temporary objects in C++, this articles contains solved example on this concept? Prerequisite: operator overloading and its rulesWhat are nameless temporary objects in C++?
You cannot have two operator + overloads which only differ in return types. Also the error messages change the name of the operator from + to op_Addition. When we overloaded functions, the return type was not considered part of the function signature. The same applies for operators. ...
Operator overloading should be a way of 'explaining the language' and providing hooks into something that's already there, rather than adding something which is a very different pattern from built-in operator definitions. Avoiding classic pitfalls of operator overloading and readability ...

Operator precedence is unaffected byoperator overloading. For example,std::cout<< a? b: c; parses as(std::cout<< a)? b: c; because the precedence of arithmetic left shift is higher than the conditional operator. Notes Precedence and associativity are compile-time concepts and are independe...
