  1. Hei ! Er det noen her som kunne tenke seg å hjelpe meg med å lage et C++ program ? Takk på forhånd. Her er beskrivelser :

     

     

    You are to write a program to manage an engineering journal. An engineering journal is a record of a person’s activities and thoughts while they work on a project. Entries are added to a journal but they can not be deleted. An employer can read a worker’s engineering journal and see how they are going.

    The format of this journal will be simple. Each entry will have a one line title and a one paragraph text entry (an example text file is provided).

    Encoding and Decoding

     

    Entries in the journal are private, so the journal is encoded and protected using a pin.

    When the program is executed it will ask for a 4¬digit pin. The pin is to be stored in the

    program as an integer array. You are to use this pin to encode and decode the journal

    entries (but NOT the titles – they are to remain in plain text).

    When saving the file, each character in the journal paragraph is to have the integer value

    of the next digit in the pin added to the character to encode. When decoding the file, the

    next digit in the pin is subtracted from the character.

     

    To encode the entry when saving to file:

    The first digit will be added to the first character of the text.

    The second digit will be added to the second character of the text.

    The third digit will be added to the third character of the text.

    The fourth digit will be added to the fourth character of the text.

    … and so the cycle repeats.

    The first digit will be added to the fifth character of the text.

    E.g. if using the pin 1234, the entry abcdefgwould be encoded bdfhfhj

    Program Features

    The program is to provide the following facilities using a menu:

    • Display a list of the titles in the journal.

    • Display the contents of a selected entry (by number)

    • Add an entry to the journal

    • Quit

     

    Error Handling

    You are to handle the errors if a file fails to open for reading or writing (with appropriate

    error messages). You should also display an error and re¬prompt the user if they do not

    enter 4 characters for the pin, or if the pin contains a non¬numeric character.

    Note that you do not need to keep the list of titles or journal entries in memory. You can read them from the file each time entries or titles are displayed. The journal file provided for this assignment is the required format you must use.

    All files should be submitted by uploading them through LearnJCU. If you do your planning by hand, you should clearly label this paper and hand it in to your lecturer.

    Planning (one document – Word doc or PDF):

     

    • IPO charts for each function with the algorithm in either pseudocode or flowchart

     

    If you are doing a flowchart, it may be hand¬drawn, but it must be neat. See your textbook examples for the desired format. This part of the assignment can be shown to your tutor during the practical in week 10, when they will make comments or suggestions. You can show them again in week 11 to confirm.

    • A completed desk¬check table

     

    This only needs to be done for one run through the program – using logical values. Name this file: LastnameFirstnameA2.doc or .docx or .pdf

    Program (one code files):

    Hand in a single .cpp file (no projects or other files). You may like to show your tutor your code during the practical in week 11 in order to get appropriate feedback. Name this file: LastnameFirstnameA2.cpp

    Note that your code must work with the journal file provided, so do not upload a new journal text file.

    Sample Output:

    Note that the following runs of the program all use the same journal.txt file above.

    Engineering Journal – Your Name

    Please enter item number: 1

    Must read the program description thoroughly. I don't want to miss out on easy marks like I did in the previous assignment.

    Select Option ([L]ist Titles, [D]isplay Item, [A]dd Item, [Q]uit): a

    Enter Title: File I/O

    Enter new item: Must remember to close the file every time it is opened. I will also need error checking in case the file fails to open.

    Save new item [y/n]: Y

    Journal entry saved.

    4. File I/O Select Option ([L]ist Titles, [D]isplay Item, [A]dd Item, [Q]uit): d Please enter item number: 4 Must remember to close the file every time it is opened. I will also need error

     

    checking in case the file fails to open. Select Option ([L]ist Titles, [D]isplay Item, [A]dd Item, [Q]uit): Q

    Note that the pin “1234” was the right pin for decoding the entry thus the entry was displayed properly.

    Another run… (same file)

    Note that although the pin format was valid and was accepted, it was the wrong pin for decoding these entries. Note also that there is no display or pause after quitting.

  2. Har en bærbar Asus Celeron M 1,4 GHz

     

    Modell: S5613N-BP

    12.1 tommers XGA skjerm 1024x768

    1,4 GHz CELERON M CPU

    256MB DDR RAM (micro So-Dimm)

    40GB HD (4200rpm)

    64MB skjermkort

     

    Spm. er om jeg kan oppgradere den til Pentium M, 80 Gb Hd 7200rpm, 768 el 1 Gb DDR RAM (er det mulig med denne modellen??), for en billigere penge enn å prøve Å selge den og investere i en ny asus, s5a (ca.12500kr), el. en annen lignende ultraportabel?

     

    Har innbilt at det er billigere å oppgradere: prislapp ca 4000 kr til sammen?

     

    Ved salg av denne modellen nå får jeg nok kun 5000-6000 kr for den: 12 500-6000=6500 kr. Da må jeg nok punge ut med minst 6000 for en hel ny maskin.

     

    Har noen prøvd å oppgradere asus s5600n Cel M og kan fortelle meg hva slags hardware jeg trenger for hvilke priser og hos hvilke forhandlere? Om det er vanskelig ell lett? Har aldri prøvd slikt før...Har noe kjennskap til data og litt om hardware, men er nok ikke noe ekspert :(

     

    HJELP, FOLKENS!

     

    Har siklet litt etter en Packard Bell ENA8840 (10 995kr på lefdal-nettpris, 9995 på elkjøp-nettpris, men de har den ikke lenger tilgjengelig på nettlager hos elkjøp), som veier 2 kg, med:

    -1 GB DDR RAM,

    -80 GB HD

    -og Pentium M 840,

     

    men den 6-cellers batteri som medfølger kjøpet varer kun i 90 min?? i følge spes. Har packard bell forholdsvis dårligere batterikapasitet i forhold til asus og generelt?

     

    Enhver forslag er verdsatt , har kun brukt min asus til lettere programmer, men vil gjerne ha den raskere til tyngre programmer... :D
