These operators are sometimes implemented as friend functions. // compound assignment (does not need to be a member, // but often is, to modify the private members), /* addition of rhs to *this takes place here */, // friends defined inside class body are inline and are hidden from non-ADL lookup, // passing lhs by value helps optimize chained a+b+c, // otherwise, both parameters may be const references, // return the result by value (uses move constructor), // records can now be compared with ==,!=, <, <=, >, and >=, // print out as 3D array using the order: X -> Z -> Y. 1 Triangle tri1 = new Triangle(2,3,4); 2 Triangle tri1 = new Triangle(10,15,20); 3 4 Triangle result = tri1 + tri2; csharp. arg: It defines the argument passed to the function.
