Programming :: Unsigned Integers In C?

Mar 24, 2009

From what I understand, if I attempt to increment an unsigned int which is already at its max value, it will flip back to zero.Question: is this guaranteed to happen by the C language? That is, can I count on this happening on all platforms?(Of course, I recognize that the max value of the int will change from platform to platform...)

Programming :: Dynamic List With Different Type - C++

Jun 26, 2010

I'm quite new to c++ programming, so my concepts are not so increased yet...

I wanna to create a list to store my objects. I'll resume them here:

Code:

private:

And what I want to do is an event list:

Code:

Sometimes this works and sometimes I got "segmentation fault".

I think I'm doing it wrong, cause these objects have different sizes, so I don't know if I could have all of them in a single array.

Programming :: Ping A List Of Devices?

Jul 27, 2010

I would like to ping all my virtual hosts in virtual machine server with a oneliner. For example like this:

Code:

for i in $(seq 1 20); do if [[ $(ping host$i.virtualhostserver.com -c 2 2>/dev/null | grep "2 received") == "2 packets transmitted" ]]; then echo $i; fi; done

The problem is, that I'm afraid my if-sentence is somewhat wrong because it never gets a match even if I know, that host is up.

Programming :: Pyqt3 List Without Comma ?

Mar 21, 2010

I'm trying to compose a line of numbers each single digit taken from a variable eg: 1010001 each variable digit is either a 0 or 1 made from variable layer1 through 7. I need to add each layer variable to the last to compose the number with no commas or spaces and add it directly after the -p option in the show_command line. I used array and list and the commas mess up the command and inserting "pens" in the show command interpertes it literally instead of the list or array value? The insert should look something like 1000110

Programming :: Create Cvs From List Text File

Dec 21, 2010

I have a file with 5000 lines. it is a list of books authors, series and titles. all lines start with the author names, than there is a dash (-) than the series name, a dash again and the title of the book.

The problem I encounter is that sometime there is a series, sometime not, and as I try to enter this list in a database, I wanted to create a cvs file to import into mysql.

ex:

The best would be to be able to add in the second line, a "space dash space" just after the author name, but how to make sure it does not do it to the first line as well.

If I could separate all line with 2 dash, (grep ?) then I would be able to do a simple replace, and change the single dash into two.
