Theless-thancomparison operator (operator<) is important to Standard Template Library operations such as sorting. We recommend that you implementoperator<if you develop a Windows Runtime component that you inten
and just return *this. ... // Deallocate, allocate new space, copy values... return *this; } Or, you can simplify this a bit by doing: MyClass& MyClass::operator=(const MyClass &rhs) { // Only
Learn how to overload a C# operator and which C# operators are overloadable. In general, the unary, arithmetic, equality and comparison operators are overloadable.
MyClass a = new MyClass(); MyClass b = new MyClass(); //equal1 is false since the operator is not called bool equal1 = a == b; //equal2 is true since the comparison operator is called from within C++\CLI bool equal2 = a.Equals(b); Run Code Online (Sandbox Code Playgroud)...

In addition, for comparison operators ==, !=, <, >, <=, >=, <=>, overload resolution also considers the rewritten candidates operator== or operator<=>. (since C++20)Overloaded operators (but not the built-in operators) can be called using function notation: std...
1As with all rules of thumb, sometimes there might be reasons to break this one, too. If so, do not forget that the left-hand operand of the binary comparison operators, which for member functions will be*this, needs to beconst, too. So a comparison operator implemented as a member fun...
Comparison operators:==,<,>,<=,>= Possibly, integer-indexed property access:[],[]= The definition of>,<=and>=is derived from<, and the definition of assigning operators like+=is derived their corresponding binary operator, for example+. ...
The comparison operators are rewritten asa.opCmp(b)op0and0opb.opCmp(a)and then the best match is used. The opCmp method must be implemented to return aintin order to be considered by the compiler. If the method argument is to be considered larger than the object then the method should...
