2. write a c or c++ program to perform the simulation: • instruct the user to make the following selections:  d: display date and time  u: unblock the queue  p: print the current status of process  t: print the process time and exit • option t can be only selected once. you need to use program to control it. • in option d, use the format mm dd year in the date and current time display. • in options u and p, you only need to print a string to show the process. we can fill in more in the next two labs. • in option t, you should make the program wait for strings and/or character(s) to calculate the time interval between the first and second processes. • hint: it is best to use structure in c++.

This problem has been solved! see the answeran evil king has a cellar containing n bottles of expensive wine, and his guards have just caught a spy trying to poison the king’s wine. fortunately, the guards caught the spy after he succeeded in poisoning only one bottle. unfortunately, they don’t know which one. to make matters worse, the poison the spy used was very deadly; just one drop diluted even a billion to one will still kill someone. even so, the poison works slowly; it takes a full month for the person to die. design a scheme that allows the evil king to determine exactly which one of his wine bottles was poisoned in just one month’s time while expending at most o(logn) of his taste testers.you are not allowed to use n testers, one for each bottle, and see which one tester dies after 30 days.(no pseudocode needed. just answer in words, how many testers you use, how you use them and why you correctly identify the poisoned bottle in 30 days)

You are consulting for a beverage distributor who is interested in determining the benefits it could achieve from implementing new information systems. what will you advise as the first step?
