0) IntroductionMagik supports both procedural language and object oriented language.Procedural Language:In procedural language all code is in modular fashion. Each module is a collection of statements. Module takes input and executes all statements step by step and gives output.EX:area > pi*radius * radius _endprocIn the above example ,procedure is taking radius as input and returning the circle area as output value. If we want to calculate area of square again we have to write one more procedure with different procedure name, though the purpose of the procedure is to calculate area. In procedural language, maintenance is headache. We can overcome this in oop language.Object Oriented Programming Language: In oop, both data and functionality is combined in a class. We can write methods with same name in different classes. For example ,we can write method area() in different classes. Methods are accessed via their class name. Ex: Circle Class: def_slotted_exemplar(:circle, {})$_method circle.new() >> _clone.init()_endmethod$_method circle.init() _return _self_endmethod$_method circle.area(r) area > _clone.init()_endmethod$_method square.init() _return _self_endmethod$_method square.area(r) area circle.area(2)$12.57142857ALL INTER VIEW QUESTIONS Which method is used to generate id value?make_sysid().
