The System maintains the ID, Name, Residential address and the Phone number (must start with Area code) for N subscribers in one dimensional arrays. Write a menu-driven application for performing the following operations. a) Accept the Subscriber’s details b) Search for records based on one of the following and display the details. (i) Name (ii) Phone Number Note: User can enter either a part of a name or in full for searching. c) Sorts the records in the ascending order of one of the following fields based on user’s choice (i) Name (ii) Phone number d) Displays the subscribers’ details in a tabular form as shown below: Address List ID Name Address Phone Number 11 RAHUL BOSE 15TH CROSS ST. 06-234 5678 12 TARUN SHARMA 14TH AVENUE 06-456 7831 Note: Store three user names and their passwords in two arrays. When the program executes, accept a user name and a password from the user, if they are valid then allow the user to work with the system, otherwise display error message and exit the program.

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?

Use a physical stopwatch to record the length of time it takes to run the program. calculate the difference obtained by calls to the method system.currenttimemillis() just before the start of the algorithm and just after the end of the algorithm. calculate the difference obtained by calls to the method system.currenttimemillis() at the start of the program and at the end of the program so that the elapsed time includes the display of the result. use the value returned by the method system.currenttimemillis() just after the end of the algorithm as the elapsed time.
