Operator overloading in C++ allows us to write natural expressions like d = a + b / c; with our own classes. The above expression could be equal to d = a.add(b.divide(c)); which results in hard to read code. Operator overloading by Example This example will add basic arithmeti...
While OverLoading a Operator always give public static access specifiers. Operator Overloading should return a CLS type and not void. Atleast one operand to the operator must be of type UDC [User Defined Class] because we cannot overload a operator with two int operands and perform subtractio...
Operators Overloading in C++ Box operator+(const Box&); Box operator+(const Box&, const Box&);Following is the example to show the concept of operator over loading using a member function. Here an object is passed as an argument whose properties will be accessed using this object, the ob...
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--....

In this way, + is overloaded with different operations depending upon the data. Source Code using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace OperatorOverloading { class Rectangle { static void Main(string[] args) { Rectangle objRect1 = new Rec...
While using the plus (+) operator on the two yyy objects, C# is aware that IL does not support operator overloading. Therefore, it creates a function called op_Addition in the class yyy. Thus, operator overloading gets represented as a mere function call. The rest of the code is ...
Screen operator++(int); // 后置操作符 shall return value(before ++), but reference many times. Screen operator- - (int); 非虚函数是静态绑定的static binding / type-declared binding (in compiling time)(即使基类指针指向的是派生类对象),虚函数是动态绑定的。Dynamic binding(in run time). ...
