Create – posaverage. java (do-while-loop) implement the following using a do-while-loop since this program will ask for a number at least one time. this is a prototypical reason for using a do-while-loop over the other two types of loops. this program asks the user to enter any number then do the following: • it adds the user input to the total if the number is positive.

Three out of five seniors remain undecided about a college major at the end of their senior year.

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?

For the following example of making a peanut butter and jelly sandwich, identify which are inputs, processes, or outputs: bread scooping and spreading peanut butter plate scooping and spreading jelly finished sandwich putting two pieces of covered bread together dirty plate crumbs
