    1) Put "sleep 300" in the perl file and run it infinitely
    2) Use shell script and use that

    These two are easier than C program. C++ - Never reinvent the wheel

    My recommendation is that you are wasting too much space for the unused characters.

    Re: Editing a single word in a file

    I agree with Lindley here. You can read the file with the censored words into an array or a Vector (safer option)

    Re: Editing a single word in a file

    You can actually create a Vector of a struct


    struct words
    {
    string word;
    int pos;
    };

    Re: Tips on getting C++ experience?

    Start redoing your Java stuff in C++ nothing different nothing new. This would mean you would end up spending less time defining and understanding the problem and more time on C++

    Re: Editing a single word in a file

    You can do the same by the following


    //GLOBAL DEFINITION
    int ast_length=0;
    char *ast;


    //WITHIN THE LOOP

    Its going to be easier to debug this using gdb or any other tool that you use. I would say the worst case once you have read both the strings print them to check the contents. This would then give...
  21. Re: Having trouble with program that reads and prints arrays

    I agree but what about the case where two distinct entries have the same number of votes which is equal to max votes.

  22. Re: Having trouble with program that reads and prints arrays

    int maxvotes=0;
    string max;
    while(!inStream.eof())
    {
    inStream >> name;
