Assignment 2 is done, i provided the source code for the main and header file as the assignments all build off the previous. Can you help?


Microsoft Word - assignment3.docx TCC CSCI 2843 Assignment 3 100 Points Due by Class 7 1) In this assignment, you will be designing and writing four classes. One of the classes will be the composite class with three members whose types are of the other three classes. 2) Each class should include a "reasonable" set of constructors to initialize their members. The composite class' constructor should take in enough information to initialize its members using their constructors in turn (in the initialization list, of course). 3) Each class will provide a public member function named output with the following signature: void output(std::ostream& s) const; The composite class' output function should be written in terms of calls to its members' output functions. 4) Overload the stream insertion operator (operator<) only="" for="" the="" composite="" class="" that="" simply="" calls="" the="" output="" function="" on="" the="" composite="" object.="" this="" can="" be,="" but="" does="" not="" necessarily="" have="" to="" be="" a="" friend.="" 5)="" each="" of="" the="" three="" member's="" classes="" must="" provide="" a="" function="" (of="" your="" own="" choosing)="" that="" "exercises"="" the="" functionality="" of="" the="" class.="" this="" exercise="" should="" involve="" some="" output="" to="" verify="" that="" the="" function="" was="" invoked,="" but="" can="" also="" manipulate="" the="" class'="" members="" in="" some="" fashion="" according="" to="" the="" design="" of="" the="" class.="" 6)="" the="" composite="" class="" must="" provide="" a="" single="" function="" that="" exercises="" its="" members="" by="" calling="" their="" functions="" that="" you="" supplied="" in="" (5)="" above.="" this="" is="" the="" delegation="" of="" the="" composite="" class="" to="" its="" individual="" members.="" 7)="" write="" a="" main="" function="" that="" instantiates="" an="" object="" of="" the="" composite="" type.="" after="" instantiation,="" output="" the="" object="" to="" cout.="" 8)="" invoke="" the="" composite="" class="" function="" you="" defined="" in="" (6)="" that="" will="" exercise="" all="" of="" its="" members="" as="" specified="" in="" (5).="" 9)="" place="" all="" classes="" in="" their="" own="" headers,="" protecting="" against="" multiple="" inclusion,="" and="" in="" a="" namespace="" of="" your="" own="" choosing.="" please="" turn="" in="" all="" source="" (and="" nothing="" but="" the="" source)="" on="" blackboard.="" assignment="" 4.pdf="" tcc="" csci="" 2843="" assignment="" 4="" 100="" points="" due="" by="" class="" 9="" 1.="" in="" this="" assignment,="" you="" will="" be="" using="" inheritance="" and="" polymorphism="" to="" implement="" a="" similar="" structure="" to="" the="" drawing/shape="" example="" in="" the="" lecture.="" for="" this,="" you="" will="" need="" to="" design="" and="" write="" a="" base="" class="" and="" three="" derived="" classes="" that="" inherit="" from="" the="" base="" (similar="" to="" the="" shape="" class="" and="" the="" derived="" shape="" classes).="" you="" will="" also="" need="" a="" “manager”="" class="" that="" will="" hold="" a="" (fixed)="" array="" of="" pointers="" to="" your="" base="" type="" (similar="" to="" the="" drawing="" class="" from="" the="" notes).="" 2.="" the="" base="" class="" may="" or="" may="" not="" have="" any="" member="" variables="" itself,="" depending="" on="" your="" design.="" the="" derived="" classes="" should="" have="" at="" least="" one="" member="" each="" to="" describe="" the="" structure/intent="" of="" that="" class.="" 3.="" you="" will="" provide="" one="" virtual="" function="" in="" the="" base="" class="" that="" each="" derived="" class="" will="" override.="" the="" base="" class’="" virtual="" function="" should="" be="" pure="" virtual="" (a.k.a.="" abstract)="" unless="" the="" base="" does="" indeed="" have="" an="" implementation.="" each="" derived="" type’s="" override="" of="" the="" virtual="" function="" should="" cause="" some="" output="" to="" std::cout="" to="" indicate="" that="" it="" was="" invoked.="" 4.="" each="" class="" should="" include="" a="" full="" set="" of="" constructors="" to="" initialize="" their="" member(s)="" as="" well="" as="" the="" base="" class.="" each="" derived="" class="" should="" call="" the="" base="" class’="" constructor="" in="" their="" initialization="" lists="" if="" needed.="" 5.="" your="" “manager”="" class="" will="" have="" an="" array="" of="" pointers="" to="" the="" base="" type="" that="" it="" manages="" and="" a="" method="" to="" add="" objects="" (by="" pointer-to-base)="" into="" the="" array="" and="" track="" how="" many="" items="" have="" been="" added.="" 6.="" include="" a="" function="" in="" the="" manager="" class="" that="" will="" loop="" through="" all="" of="" the="" objects="" in="" the="" array="" and="" invoke="" the="" virtual="" function="" for="" each="" element="" (just="" like="" drawing::draw="" looped="" through="" all="" of="" its="" shapes).="" 7.="" in="" your="" main="" function,="" instantiate="" a="" “manager”="" object.="" 8.="" add="" several="" objects="" of="" your="" types="" to="" the="" manager="" object.="" these="" objects="" will="" have="" to="" be="" created="" dynamically="" (with="" new)="" and="" passed="" into="" the="" function="" you="" made="" in="" (5)="" that="" will="" add="" the="" objects="" to="" the="" array.="" 9.="" call="" the="" manager="" object’s="" function="" from="" (6)="" that="" will="" loop="" through="" all="" objects="" you="" just="" added.="" 10.="" make="" sure="" that="" the="" manager’s="" constructor="" cleans="" up="" all="" of="" its="" objects="" when="" the="" manager="" object="" goes="" out="" of="" scope.="" 11.="" place="" all="" classes="" in="" their="" own="" headers=""

employee { private: std::string first_name; std::string last_name; float monthly_pay; public: . . . }; You should provide any and all required constructors, access functions, and the operator<. 2)="" write="" a="" main="" function="" that="" opens="" a="" std::ifstream="" on="" the="" input="" file,="" "employee.dat"="" and="" a="" std::ofstream="" on="" an="" output="" file,="" "update.dat".="" if="" either="" stream="" cannot="" be="" opened,="" throw="" an="" exception="" and="" exit="" (hopefully="" with="" a="" useful="" diagnostic="" message).="" the="" file="" format="" is="" line-oriented="" and="" comma-delimited="" in="" the="" following="" format:="" last_name="" comma="" first_name="" comma="" monthly_pay="" newline="" 4)="" write="" a="" loop="" that,="" for="" each="" line="" in="" the="" file,="" reads="" from="" the="" std::ifstream="" and="" creates="" an="" employee="" object="" (i.e.="" first="" name,="" last="" name,="" and="" pay).="" on="" detecting="" end-of-file,="" exit="" the="" loop="" and="" end="" the="" program.="" if="" there="" is="" an="" error="" reading="" the="" information,="" throw="" an="" exception="" and="" exit="" the="" program.="" for="" each="" employee="" read,="" increment="" their="" monthly_pay="" by="" $50.00="" (everybody="" gets="" a="" raise).="" 5)="" while="" in="" the="" loop,="" after="" they="" get="" their="" raise,="" output="" each="" employee="" to="" std::cout="" and="" to="" the="" output="" file="" using="" the=""><. use the given file, employee.dat, for example input, but you should try some exceptional cases to make sure your code can detect and properly handle them. note - do not store the employee information – this is just an exercise in i/o – we will store objects that we have read in a later assignment. once the employee has been output, just let it go out of scope. 6) for all exceptions, make sure an error message detailing the cause of the exception is printed to the console before exiting the program. any further information (i.e. file and line number of exception) is purely optional. employee.dat horowitz,jake,1200.24 flabitz,bubba,1712.38
