Now the+operator in the above code performs subtraction of points. Even though the program works without errors, you should absolutley avoid this. We should always use oeprators appropriately during operator overloading. Similarly, we can overload other operators as well. The special function that...
In this section we will look at + and *, but the technique can apply to any operator. Matrix addition Just to recap the basics of matrix algebra, the sum of two matrices: (abcd)+(efgh) is (a+eb+fc+gd+h) Overloading the addition operator You can override the addition operator ...
{1}i", real, imaginary)); } // Overloading '+' operator: public static ComplexNumber operator+(ComplexNumber a, ComplexNumber b) { return new ComplexNumber(a.real + b.real, a.imaginary + b.imaginary); } // Overloading '-' operator: public static ComplexNumber operator-(Complex...
Operator overloading involves many concepts, some of which will be covered later in the book (templates,auto ref, etc.). For that reason, you may find this chapter to be harder to follow than the previous ones. Operator overloading enables defining how user-defined types behave when used ...
Often operators are preferred over real names if the operators are already familiar to the users. In fields such as mathematics or physics, where operators are routinely used, it would be natural to also use operations in code where appropriate. For example, in the case of matrices, using the...

Learn how to overload a C# operator and which C# operators are overloadable. In general, the unary, arithmetic, equality and comparison operators are overloadable.
Computer Science - Programming LanguagesThe paper introduces a modular extension (plugin) for Java language compilers and Integrated Development Environments (IDE) which adds operator overloading feature to Java language while preserving backward compatibility. The extension use the idea of library-based ...
Welcome to your next lesson in Object-Oriented Programming in Python versus Java. In this lesson, we will take a look at operator overloading. You saw in your last lesson that Python provides a lot of built-in methods that objects inherit from…
作者: F Programming 摘要: Overloaded operators are a new feature in Visual Basic 2005 (VB 2005), providing the capability long available in C++ and C#. Just as you can overload methods, you can overload operators such as +, −, and *. In addition to overloading arithmetic operators, ...
