It should be possible to rendezvous with CountDown and start a countdown with a specified period (for example 20 seconds) and display the countdown (20, 19, 18 ... etc.) at a specified place on the screen as time elapses until either:zero is reached when audible and visible indications should be given that the countdown has expired,orthe task accepts a entry request from another task to end the countdown. Develop a program (which employs the above tasks) which displays the current time of day at a suitable position on the screen and reads multiple choice questions from a file whose name should be supplied on the command-line when the program is invoked. The program should display the questions on the screen one at a time and start a countdown for each question.The format each question in the file is to be as follows: a single character denoting the correct answer a positive integer identifying the countdown time in seconds allowed for this question the text of the question (on one or more lines) terminated by a line containing only the string END_OF_QUESTION. This terminator should not, of course, be displayed with the question. the possible answers (one per line) terminated by a line containing only the string END_OF_ANSWERS.For example a typical question in the file might have the form:b 10What is the capital of Slovenia?END_OF_QUESTION(a) Bratislava(b) Ljubljana(c) Sarajevo(d) ZagrebEND_OF_ANSWERSIf the user presses a key before the countdown time (10 seconds in the above example) has expired, the program should respond by outputting either Correct! or Wrong. The correct answer was (b).as appropriate. The case of the character typed should be ignored in determining whether the answer is right or wrong. If no key is pressed before the countdown expires, a suitable message including the correct answer should be output. This message should be left on the screen for a suitable time to enable the user to read it.The screen should then be cleared, another question displayed and a new countdown started and so on until the end of the questions file is reached. The program should then display a summary of the user's performance on the test, that is the number of correct answers obtained, the number of incorrect answers, the total number of questions in the test and the total time taken in minutes and seconds to complete the test. The program should then terminate.
Submission requirements:1. A line-printer listing of your Ada program.2. A brief word-processed account (no more than 300 words) of the structure of your program including a discussion of any requirements for synchronisation of execution, data access/update and I/O operations.3. An account of any 'bugs' or 'features' of your program that you have been unable to correct. Additional marks will be deducted if your program contains obvious 'bugs' and 'features' that are not properly documented. Hence it is in your interests to thoroughly test your program and to document truthfully any such uncorrected bugs that have come to light in your testing.Submit your work to Computer Science Reception, room MB216C, by: 4.30 pm on Thursday May 8th, 2003Work handed in after the due date will incur a penalty of 1 marks (from a total of 25 marks) per working day. A Computer Science Coursework Submission Form (available from CS Reception) must be completed and attached to the front of your submission. No submissions will be accepted after 4.30 pm on Friday May 23th, 2003.Important notes:Your documentation should be word-processed.Your program MUST be printed: directly from files stored in your UNIX user area on a University line-printer using continuous sheet perforated paper with the perforations unbroken AND with the leading banner page still attached to each listing (this contains your UNIX userID, the name of the file and the date of printing, etc.).If you fail to hand in the listing in the form specified, you will be awarded a zero mark for the assignment. You must retain a copy of the program that you submit in your UNIX user area. The marker coursework may wish to inspect this at a later stage.Although you are welcome to discuss the coursework with your colleagues and raise any problems you may have relating to this assignment with the lecturing, tutorial and demonstrating staff, your final submission must be prepared on an individual basis.It is an offence under University regulations to submit work which has been plagiarised (copied) or produced by collusion (working together). Disciplinary action is always taken against students whose coursework submissions infringe these regulations. Students are advised to read the notice on Doing Coursework for Computer Science Modules which is posted on all relevant Computer Science programme notice boards.If your program doesnt workSome credit will be given for partial solutions. Thus, even if your program is incomplete or does not execute correctly, you should hand in what you have done. If your program fails to compile, you should also hand in a full compilation listing (a listing as produced by the compiler gnatmake when invoked with the option -gnatl). If your program fails to execute correctly and terminates with a run-time error, you should also hand in a description of what actions you have taken to identify the cause of the run-time error (e.g. use of the run-time debugger), together a statement of what you think is causing the error.
