C++ Questions Part 4(End)

Thank you for all your help.

26) Could you use the maximum finding function object you designed in #22 to help with processing the scores from 25? If so, how? If not, why not? 27) When a data file has a block structure such that each block has information about a particular item (e.g. a bank patron, a self-sealing stem-bolt, an inventory item, a sample taken at a geological dig, etc.), the file's data would be most effectively read by a loop: A) in the main program with each block going into parallel spots in many containers B) in the main program with each block going into a class-type variable, processing it before moving on to the next block C) in a class method with each block going into parallel member containers D) in a class method with each block going into member variables to be processed before reading the next block E) in the main program with each block going into an element of a class-type based container for later processing 28) How would you allow the user to place comments in a data file? Explain briefly. 29) Recalling that ' y can be rewritten as x.operator(y (when x is an object of a class for which operator+ has been overloaded as a member function taking an argument of y's type), rewrite each of the following expressions as operator function calls. Use non-member operator versions only when necessary. Assume all variables are objects with appropri- ate overloading available. Assume all class operations return a class object- where reasonable. (And, yes, all of these operators exist and are overload-able.) x=y*2 n q &S o(42, t-u, rh) 42. t-u 30) Write a two-line function to determine and return the length of a caller-specified input stream (measured in bytes). (Thought-provoker: The line count would be five if you cleaned up after yourself) (Thought-provoker: What should the return-type of your function be?)
