As some of you noticed, there is a little problem while creating an array and a pointer of it in C++. For doing that, you are supposed to write something like:

int data[50];		// declare an (static) array
int *p_data = data;	// make a pointer of it

// declare a function, which gets the pointer of the data array
void function(..., int* p_data, ...);

// Call-by-reference
function(..., p_data, ...)

If you don't want to have a static array but a dynamic one, you need to ask the user for the length and then reserve some memory for it.
Thanks to: Fred Swartz:

int* a = NULL;   // Pointer to int, initialize to nothing.
int n;           // Size needed for array
cin >> n;        // Read in the size
a = new int[n];  // Allocate n ints and save ptr in a.
for (int i=0; i<n; i++) {
    a[i] = 0;    // Initialize all elements to zero.
}
...  // Use a as a normal array
delete [] a;  // When done, free memory pointed to by a.
a = NULL;     // Clear a to prevent using invalid memory reference.

If you need it all over dynamic, to grow and shrink depending on what the user wants, you could use malloc and remalloc memory for an array (like you would do it in C). But you could also use std::vector (declared in vector.h) which does all what you need:

std::vector<int>  data;
std::vector<int>* p_data = &data;

// declare a function, which gets the pointer of the data vector
void function(..., int* p_data, ...);

// Call-by-reference
function(..., p_data, ...)

Spaeter am Abend verschlug es uns in die Cuba Bar. Richtig nette Location mit leckeren Cocktails. ;-)

Danach lief ich zurueck nach Bayenthal. 11 U-Bahn-Stationen zu laufen ist allerdings nicht gerade um die Ecke. ;-)

Angefangen hat alles mit der Anreise am Dienstag. Wir sind in einen elendlangen Stau geraten, der durch Nebel verursacht worden war. Nun standen wir dort und warteten 6 geschlagene Stunden.

In Koeln angekommen standen nun die WG-Besichtigungen auf dem Plan. Leider wussten meine Favouriten nur zur Haelfte Bescheid und so ueberrannte ich sie etwas mit meinem spontanen Einzug.
Dafuer sind hier alle super nett und ich freue mich wirklich hier gelandet zu sein. Koeln-Bayenthal ist auch eine wunderschoene, ruhige Gegend.

Mein Praktkikumsplatz fuer die naechsten Monate wird die undbitte entertainment GmbH sein. Es ist ein sehr angenehmes Arbeitsklima dort. :-)

The university marked it (together with a presentation) as 2.0. :-)

My highlight is that a downtime of a service will notify me via Twitter. Furthermore the Gentoo Nagios guide helped my very much. There exist several Nagios plugins to check ssh, jabber, irc and other tcp ports and many other things to monitor.

If somebody knows a free Nagios infrastructure I'll be interested in this. :-)

There were a lot of talks of several difference topics. But don't forget the social part of such events. I met several people, I never met before in real life. It was really fantastic.
