* Was ist Aliasing?
*
* Aliasing tritt auf, wenn zwei oder mehr Referenzen, Zeiger oder Variablen
* auf denselben Speicherort verweisen. Das bedeutet, dass eine Änderung des
* Werts über eine Referenz auch den ursprünglichen Speicherort beeinflusst,
* auf den andere Referenzen zeigen. In diesem Beispiel wird Aliasing durch
* Referenzen demonstriert.

/* (Call By Reference vs Call By Value)?
* - Call By Value:
* * wird der Wert eines Arguments in die Funktion kopiert. (siehe Beispiel)
* Das bedeutet, dass Änderungen, die innerhalb der Funktion an dem Parameter vorgenommen werden, keine Auswirkungen auf das Original haben.
*
* - Call By Reference:
* * wird durch die Verwendung von Referenzen (&) oder Zeigern (*) möglich.
* Änderungen am Parameter wirken sich direkt auf die ursprüngliche Variable aus.
*
* * Wichtige Unterschiede:
* 1. Referenzen (int&):
* - Funktioniert als ein Alias für die ursprüngliche Variable. Die
* Funktion erhält direkten Zugriff auf die Variable, ohne dass
* die Adresse explizit übergeben werden muss.
* Kein &-Symbol beim Funktionsaufruf notwendig.
*
* 2. Zeiger (int*):
* - Ein Zeiger speichert die Adresse der Variablen. Damit die
* Funktion weiß, wo die Variable im Speicher steht, muss die Adresse übergeben werden.
* & ist beim Funktionsaufruf notwendig, da du die Adresse übergeben musst.
