Topics: Structures, Arrays, Searching and Sorting Assume there is a small mobile computer device including a hard disk and a slot for a memory card. The device shall be used to backup photos e.g. during holiday. Every time a memory card is connected all photos of the card are copied into a new folder automatically. And your task is to develop some basic controlling software to show, add, remove, search and sort the directories of photos. Step by Step Implementation 1.Define two symbolic constants, one to hold the total volume of the disk (e.g. VOLUME) and another one to hold the number of entries the files system of the device can handle (MAXFOLD). 2.Define a new structure data type named DATE to store a date consisting of year, month and day as unsigned values. 3.Define an other structure data type FOLDER to store the information of one folder of photos: ◦A title as character array of appropriate length ◦The location (event) the photos are taken as character array of appropriate length ◦The date of the day the photos are copied to the disk using the just defined data type DATE ◦The number of photos as natural number ◦And the size of the folder in MB as floating point value 4.Define the following global variables and initialise them: ◦disk as an array with MAXFOLD elements of data type FOLDER ◦folders as natural value to count the number of folders currently stored at the disk (valid elements in the array) TEST: Now you should be able to compile the code the first time without any warning or error. In the menu only "p" to print and "q" to quit will work!. 5.Now complete the functions given by their prototype: float freeSpace ();The function has to calculate the sum of the size component of all elements currently stored in the disk array. The function shall return the free space of the disk by the difference between the available total volume and the calculated sum. TEST: To test this function you only need to uncomment printing the "statusline" at the function actionmenu(). Compare the calculated value with a manual calculation of the example values given above. unsigned isBefore (DATE, DATE);The function checks if one date is before the other. There are 3 different possibilities which have to be handled. Imagine for example these 3 different combinations of values: ◦2010-01-01 : 2010-01-02 ◦2010-01-01 : 2010-02-01 ◦2010-01-01 : 2009-01-01 The function shall just return the result of the comparison. unsigned isEqual (DATE, DATE);The function checks if one date is equal to the other, all components have to be compared. The function shall just return the result of the comparison. int findByDate (DATE);As the array is should be kept in order (sorted by date) implement a binary search for a folder by its date here. You need only to adapt the binary search we used in the exercise. Use the 2 comparing functions above where appropriate. The function shall return the index of the element which was found or -1. TEST: Now you can try searching a folder by date via the "s" in the menu. Activate the corresponding part in the main function. int isSpaceLeft (FOLDER);This function compares the free space of the disk with the size of folder given with the parameter list. The function shall return 1 if there is enough space to add the folder, otherwise 0 (just the result of the comparison). void SortByDate ();This function shall implement the InsertionSort using the component date as key. Use the provided algorithm/souce code of the exercise as template. If you need a comparison between dates, use the function isBefore you have written again. void addFolder (FOLDER);The function has to check if the disk has additional capacities to add the new folder (number of folders and space left). If at least one of these conditions is false print an error message and return -1. Else there has to be added an other test to avoid 2 folder elements with the same date (use the findByDate function here. If there is no folder with the new date simply attach the new folder at the end of the array and call the sorting algorithm afterwards to keep the order in the array. TEST: Now you can try to add a folder via the "a" in the menu. Activate the corresponding part in the main function. void delDir (int);This function removes one element of the disk array. The input parameter contains the index of the element to delete. Deletion can simply be done by moving all elements at the right one to the left (overwriting the element to delete. The function may get a -1. This has to be checked first (certainly there is nothing to delete then!) Don't forget to decrement the counter of elements at the end. TEST: Now you can try to remove a folder by date via the "r" in the menu. Activate the corresponding part in the main function. unsigned findAllOfLocation(char[], FOLDER[]);This is an optional additional task: The function shall find all elements with the given value for the component location (first input parameter). The array elements which are found have to be added to the FOLDER array (second input parameter). As this parameter is an array we can use the result later in the main function. There kernel of function implements a modified linear search on the disk array (it does not stop if one element is found bat continues search until the location of all elements is checked). The finally function shall return the number of elements found in the disk array. TEST: Now you can try to add a folder by date via the "l" in the menu. Activate the corresponding part in the main function.

If one always ought to act so as to produce the best possible circumstances, then morality is extremely demanding. No one could plausibly claim to have met the requirements of this "simple principle." . . . It would seem strange to punish those intending to do good by sentencing them to an impossible task. Also, if the standards of right conduct are as extreme as they seem, then they will preclude the personal projects that humans find most fulfilling. From an analytic perspective, the potential extreme demands of morality are not a "problem." A theory of morality is no less valid simply because it asks great sacrifices. In fact, it is difficult to imagine what kind of constraints could be put on our ethical projects. Shouldn't we reflect on our base prejudices, and not allow them to provide boundaries for our moral reasoning? Thus, it is tempting to simply dismiss the objections to the simple principle. However, in Demands of Morality, Liam Murphy takes these objections seriously for at least two distinct reasons. First, discussion of the simple principle provides an excellent vehicle for a discussion of morality in general. Perhaps, in a way, this is Murphy's attempt at doing philosophy "from the inside out.". . . Second, Murphy's starting point tells us about the nature of his project. Murphy must take seriously the collisions between moral philosophy and our intuitive sense of right and wrong. He [must do so] because his work is best interpreted as intended to forge moral principles from our firm beliefs, and not to proscribe beliefs given a set of moral principles. [Murphy] argues from our considered judgments rather than to them. . . For example, Murphy cites our "simple but firmly held" beliefs as supporting the potency of the over-demandingness objection, and nowhere in the work can one find a source of moral values divorced from human preferences. Murphy does not tell us what set of "firm beliefs" we ought to have. Rather, he speaks to an audience of well-intentioned but unorganized moral realists, and tries to give them principles that represent their considered moral judgments. Murphy starts with this base sense of right and wrong, but recognizes that it needs to be supplemented by reason where our intuitions are confused or conflicting. Perhaps Murphy is looking for the best interpretation of our convictions, the same way certain legal scholars try to find the best interpretation of our Constitution. This approach has disadvantages. Primarily, Murphy's arguments, even if successful, do not provide the kind of motivating force for which moral philosophy has traditionally searched. His work assumes and argues in terms of an inner sense of morality, and his project seeks to deepen that sense. Of course, it is quite possible that the moral viewpoints of humans will not converge, and some humans have no moral sense at all. Thus, it is very easy for the moral skeptic to point out a lack of justification and ignore the entire work. On the other hand, Murphy's choice of a starting point avoids many of the problems of moral philosophy. Justifying the content of moral principles and granting a motivating force to those principles is an extraordinary task. It would be unrealistic to expect all discussions of moral philosophy to derive such justifications. Projects that attempt such a derivation have value, but they are hard pressed to produce logical consequences for everyday life. In the end, Murphy's strategy may have more practical effect than its first-principle counterparts, which do not seem any more likely to convince those that would reject Murphy's premises. 1) The author suggests that the application of Murphy's philosophy to the situations of two different groups: a) would help to solve the problems of one group but not of the other. b) could result in the derivation of two radically different moral principles. c) would be contingent on the two groups sharing the same fundamental beliefs. d) could reconcile any differences between the two groups. 2) Suppose an individual who firmly believes in keeping promises has promised to return a weapon to a person she knows to be extremely dangerous. According to Murphy, which of the following, if true, would WEAKEN the notion that she should return the weapon? a) She also firmly believes that it is morally wrong to assist in any way in a potentially violent act. b) She believes herself to be well-intentioned in matters of right and wrong. c) The belief that one should keep promises is shared by most members of her community. d) She derived her moral beliefs from first-principle ethical philosophy. 3) The passage implies that a moral principle derived from applying Murphy's philosophy to a particular group would be applicable to another group if: a) the first group recommended the principle to the second group. b) the moral viewpoints of the two groups do not converge. c) the members of the second group have no firmly held beliefs. d) the second group shares the same fundamental beliefs as the first group. 4) According to the passage, the existence of individuals who entirely lack a moral sense: a) confirms the notion that moral principles should be derived from the considered judgments of individuals. b) suggests a potential disadvantage of Murphy's philosophical approach. c) supports Murphy's belief that reason is necessary in cases in which intuitions are conflicting or confused. d) proves that first-principle strategies of ethical theorizing will have no more influence over the behavior of individuals than will Murphy's philosophical approach. 5) Which of the following can be inferred about "doing philosophy from the inside out?" a) Murphy was the first philosopher to employ such an approach. b) It allows no place for rational argument in the formation of ethical principles. c) It is fundamentally different from the practice of first-principle philosophy. d) It is designed to dismiss objections to the "simple principle." 6) A school board is debating whether or not to institute a dress code for the school's students. According to Murphy, the best way to come to an ethical decision would be to: a) consult the fundamental beliefs of the board members. b) analyze the results of dress codes instituted at other schools. c) survey the students as to whether or not they would prefer a dress code. d) determine whether or note a dress code has ever been instituted in the school's history
