  2. 3rd example review :
    compatiable only with turbo c++ 3.0 (bluecsreen) [in windows XP]but processor fault occurs in the line -> *bar=toupper(*bar) during runtime in turbo c++ 4.5 (white screen) [in windows 7]& also it runs in compiler named dev c++ 5.0.0.9[in windows XP] without waiting for getch() [I added #include before main() & getch() in main() in the source code] & in dev c++ 5.4.0 [in windows 7] before printing “MY SAMPLE STRING”, message box the “program has stopped working” comes.
    -more about 1st example if you have been seen this comment & reply me

  3. I tried your code to write greek in LaTex without changing anything. It didn’t work in my opensuse 13.1. I got the notification: fontspec.sty, mistake, line 41, “The fontspec package requires either XeTex or LuaTex to function. It seems it has to do with the new version of opensuse (13.1 is just released). With the older version 12.3 I had no problem writing in greek. I’m trying to find a solution. Thanks Leon!

    • Hi Leon,

      I am not confident with opensuse. However, in my editor ( MikTex I think it was..been a long time since I wrote in LaTex🙂 ), I remember that I should change something in the left upper corner, from the default option to something else (xeLaTex maybe).

      Sorry, for not being precise, but I am in a different OS at this period. My guess is, that you have to change your default option to XeTex or LuaTex. Google didn’t help me to find where is this option. I guess you should look for it in the toolbar.. I am just guessing, I do not know..

      In my editor, things would look like this http://www.tug.org/texworks/img/texworks-win7.png
      You can see the pdfLaTex option in the left upper corner. There, I would click on it and a drop down list would appear, containing the “correct” option I should use (in your case XeTex or LuaTex). Then I would recompile and everything would work.

      If I were you, I might consider not to upgrade now to opensuse 13.1, if the problems persist. I have the feeling that opensuse might be not an editor, but I do not know for sure!

      Hope you find the fix,
      George

  4. Hi. I am having problems in using scanf. Im pretty sure this is correct: scanf(“%c”,answer); when im trying to get a one-character input from the user. The problem is, when it is inserted into my code which involves files and structures, the program gets warnings, ive tried &answer but it only scans the character and does not do the rest of the code. Please enlighten me on how to do this. What could be the problem? Thanks!

  5. Hi George,
    I implemented your quick sort in my Filters class as SORT filter and it works fine for the first run but when I run SORT twice the second run is too slow, could you help me to understand if it is a bug in my code or in yours? Thanks.

    WRITE FILE ‘V2IBAVM.TEMP.T2’
    FILTERS (SORT 1.4 6.13 20.10 D )
    SELECT * FROM CPEHOLD.CAPACITY
    order by start_date;
    *** SORT CPU=0.0452 sec, 41675 recs, 1 calls, 57165 loops, 981877 compares — FAST!!
    *** VALUES (
    *** 1.4 — LOC (CHAR)
    *** , 6.13 — RESOURCE (CHAR)
    *** , 20.10 — START_DATE (DATE)

    *** , 49.17 — MIN_CAPACITY (DECIMAL)
    *** , 67.8 — PGM_ID (CHAR)
    *** , 76.26 — LAST_UPDATE (TIMESTAMP)

    • Hi Vladimir. Performance has to do with the order of the input. Notice that my implementation is for demonstrative purposes only, it is not much efficient. So, if you are looking for a fast implementation of quicksort(), you should search elsewhere.

      • Thanks George, I tried some implementations from other sites but they do not sort big files correct, your implementation is correct but slow on already sorted files, too many calls of a compare function…
        Looks like I should investigate how to use std::sort() of C++…

  6. *I Want to read a set of data contains in a file which are in different types ( int, double and string types) string type data contain more than one word ,

    file type is txt file

    It contains files in following pattern bookid (intiger) book category (string) book name ( string) book price ( double) each data is in seperate lines and no label is there as I types only values and names are there

    how to read them and print? please help me to fix this issues*

  7. On stackoverflow you made a reference to your isPrime.c program.

    Here is a somewhat shorter version:

    #include

    int isPrime (const int);

    int main(void)
    {
    int i;
    for (i = -1 ; i <= 15 ; ++i)
    printf("%d is %sprime\n", i, isPrime(i) ? "" : "NOT ");
    return 0;
    }

    int isPrime (const int number)
    {
    int i, prime = 1;

    if ( number <= 1 )
    prime = 0;

    for ( i = 2; (i <= number / i) && prime ; i += ( i == 2 ) ? 1 : 2 )
    if ( number % i == 0 )
    prime = 0;

    return prime;
    }

    This must have been one of your first programming efforts. You should, of course, also use booleans for prime and also for the value returned by the isPrime function.

    • ringzero, thank you, would you be so kind to post it here instead, since at this section, nobody will see it.

      And yes, you are right! This was hw in ip back in 2010!🙂
