The program asks the user to enter the time the call is made (day, evening, or night) and the duration of the call (a number that can have one digit to the right of the decimal point). If the duration of the call is not an integer, the program rounds up the duration to the next integer. The program then displays the cost of the call. Run the program three times for the following calls: (a) 8.3 min at 1:32 P. M. (b) 34.5 min at 8:00 P. M. (c) 29.6 min at 1:00 A. M.

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?

While inserting images, the picture command is usually used to insert photos from a digital camera, and the clip art command is usually used to a.edit the sizes and other characteristics of photos that have been inserted. b.take a screenshot of an image and copy it to the clipboard for pasting. c.search for drawings or other images from a library of prepared pictures. d.make illustrations using lines and shapes that are easy to manipulate.
