Binary operators, when overloaded, are given new functionality. The function defined for binary operator overloading, as with unary operator overloading, can be member function or friend function. The difference is in the number of arguments used by the function. In the case of binary operator...
The unary operators operate on the object for which they were called and normally, this operator appears on the left side of the object, as in !obj, -obj, and ++obj but sometime they can be used as postfix as well like obj++ or obj--....
Sr.No.Operators & Description 1 +, -, !, ~, ++, -- These unary operators take one operand and can be overloaded. 2 +, -, *, /, % These binary operators take one operand and can be overloaded. 3 ==, !=, <, >, <=, >= The comparison operators can be overloaded. 4 &&, ...

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: ...
For Binary public static ret-type operator op(parameter-type operand1, parameter-type operand1) { } C# Copy Example First we look at an example of a unary operator(++): class calculation { int a, b, c; public calculation() { a = b = c = 0; } public calculation(int x, int y,...
Unary operators The following example shows the syntax to overload all the unary operators, in the form of both global functions (non-member friend functions) and as member functions. These will expand upon the Integer class shown previously and add a new byte class. The meaning of your parti...
The following operators are rarely overloaded: The address-of operator, operator&. If the unary & is applied to an lvalue of incomplete type and the complete type declares an overloaded operator&, it is unspecified whether the operator has the built-in meaning or the operator function is ...
