A class named CafeService contains  Two data members i. e. the orderID and the price of food item(s) served by
 A no-argument constructor to initialize both data fields with default values of “ord#0”, 0.0
 A parameterized constructor to initialize all data fields with user-defined values
Derive a class named StaffService from the class CafeService that holds the following:
 Two data members i. e.
o serviceFee,
o the cabinNumber to which the service has been made
 A function named totalCharges that returns total cost of an order (including serviceFee + price of food item(s) served)
 A parameterized constructor, which requires arguments for all of its own data fields as well as for the data fields of base class
 A member function named display() to show all the details of an order including orderID, price, and totalCharges
In the main() function, instantiate an object of class StaffService object and test the implementation of both classes through this object.

When making changes to optimize part of a processor, it is often the case that speeding up one type of instruction comes at the cost of slowing down something else. for example, if we put in a complicated fast floating-point unit, that takes space, and something might have to be moved farther away from the middle to accommodate it, adding an extra cycle in delay to reach that unit. the basic amdahl's law equation does not take into account this trade-off. a. if the new fast floating-point unit speeds up floating-point operations by, on average, 2ă—, and floating-point operations take 20% of the original program's execution time, what is the overall speedup (ignoring the penalty to any other instructions)? b. now assume that speeding up the floating-point unit slowed down data cache accesses, resulting in a 1.5ă— slowdown (or 2/3 speedup). data cache accesses consume 10% of the execution time. what is the overall speedup now? c. after implementing the new floating-point operations, what percentage of execution time is spent on floating-point operations? what percentage is spent on data cache accesses?
