Assume one file has r =106 records. each record takes r = 100 bytes, of which 10 bytes are for the key of the record. suppose the key values range from 1 through 1,000,000, inclusive. assume the block size b is 1000 bytes for all files, and that an address (block pointer, tree node pointer, or data record pointer) takes 10 bytes.
3. multilevel index: (15 points)
i. what is the fan-out value if multi-level index is used?
j. how many levels are there so that top level index fits on a single block in multilevel index?
k. how many block accesses are needed to fetch a record by using multilevel index?
l. what is the key value of the 4th index record on the top level, assuming each index record points to the record with the highest key value in a block of the next level down?

Define a class named movie. include private fields for the title, year, and name of the director. include three public functions withprototypes void movie: : settitle(cstring); , voidmovie: : setyear(int); , void movie: : setdirector(string); . includeanother function that displays all the information about a movie. write a main() function that declares a movie object namedmyfavoritemovie. set and display the object's fields. this is what i have but know its wrong since it will notcompile: #include#includeusing namespace std; //class declarationclass movie{private: string movietitle ; string movieyear; string directorname; public: void settitle(string title); void setyear(string year); void setdirector(string director); void displayinfo(); }; //class implementationvoid movie: : settitle(string title){ movietitle = title; cout< < "what is the title of themovie? "< > temp; myfavoritemovie. settitle(temp); cout< < "enter movie year"< > temp; myfavoritemovie. setyear(temp); cout< < "enter director'sname"< > temp; myfavoritemovie. setdirector(temp); //display all the data myfavoritemovie. displayinfo(); system("pause"); return 0; this code is not entirely mine someone on cramster edited my firstcode but then i try manipulating the new code and i still get acompile error message : \documents\visual studio 2008\projects\movie\movie\movie. cpp(46) : error c2679: binary '< < ' : no operator found which takes aright-hand operand of type 'std: : string' (or there is no acceptableconversion)c: \program files (x86)\microsoft visual studio9.0\vc\include\ostream(653): could be'std: : basic_ostream< _elem,_traits> & std: : operator< < > (std: : basic_ostream< _elem,_traits> & ,const char *)w
