pos1.x + pos2.x = 8 pos1.x + pos1.y = 4 It does NOT mean: pos1.x + pos1.y, because pos1 and pos2 have both x and y values */ std::cout << "\n\nExample 2 - pos1 + pos2 with Operator Overloading" << std::endl; std::cout << "\tx + x = " << new_pos...
When look into the above snapshot,it had invoked the overloaded assignment method and print the identical information. But to my surprise,their addresses are different as below,think further,because they are different objects and called constructor respectively....
When a user-defined class overloads the function call operator operator(), it becomes a FunctionObject type. An object of such a type can be used in a function call expression: // An object of this type represents a linear function of one variable a * x + b. struct Linear { ...
// assignment operator, generated by compiler Complex<T>& operator=(Complex<T> const& other) = default; // addition Complex<T> operator+(Complex<T> const& rhs) const; // this could be a template method with any Complex<S> convertible to Complex<T> Complex<T>& operator+=(Complex<T>...

Operator() is sometimes overloaded with two parameters to index multidimensional arrays, or to retrieve a subset of a one dimensional array (with the two parameters defining the subset to return). Anything else is probably better written as a member function with a more descriptive name. ...
您的运算符需要non-constant个引用: complex operator^(complex& lhs, complex& rhs); 在表达式return a ^ complex(1/2)中,第二个运算符是r-value。尝试使用常量引用定义...
1) 成员候选:如果 T1 是完整类或当前正在定义的类,那么成员候选集是对 T1::operator@ 进行有限定的名字查找的结果。所有其他情况下,成员候选集为空。2) 非成员候选:对于运算符重载容许非成员形式的运算符,为在表达式的语境中对 operator@ 进行无限定名字查找(可能涉及 实参依赖查找)所找到的所有声明,但忽略成员...
