![]() ![]() Unlike any other data type, a pointer data type is the only data type that can use data types not declared yet.īelow you will see a usage scenario, but let’s continue in the script. The domain restriction, the specification of targeted value’s data type, tells the compiler “how large” a memory block will be, and in consequence how to properly read and write, how to access it. There is no statement with respect to this block’s size, its length. This is because a pointer alone is just an address:Īn address merely points to the start of a memory block. In Pascal all pointer data types have to indicate the data type of the value the pointer is referring to. Program pointerDemo ( output ) type charReference = ^ char Ī variable of this pointer data type can point to a single char value (and no other data type). In Pascal, a pointer data type declaration starts with a ↑ (up arrow), or alternatively and more frequently the ^ (caret) character, followed by the name of a data type. It is pointing, but not making any statement as regards to “whom”, what variable this block of memory “belongs.” This address can then be used to access the memory it is referring to. The pointer data type is a value that stores an address. ![]() When you want to refer to a certain memory block, you use its address. ![]() ĭynamic variables, however, are, hence their name, dynamic in that they will be occupying different, unpredictable memory segments.Īn address is, in CS, simply a number, an integer value so to speak. While using static variables, the compiler already knows which memory chunk will be used in advance. That means, there is no static memory allocated, but the used memory space varies each time the program runs. They do not necessarily “exist” during the entire block. ![]() There is another kind called dynamic variables.while a program is running or just during execution of a routine. They exist during the entire execution of a block, e. g. So far we have been using static variables.lina knörr) the observer gets a view inside my impulsive, intense, overloaded and insecure world of my head.In Pascal there are two kinds of variable types. Through trying to escape those repeating thoughts i turned to painting and popmusic, where i tried to process those emotions and pain feels of the last months, something that seemed impossible through my usual outlet of playing the trumpet and jazz/contemporary music/composition.Ĭonnected with light installations, live processing of the structural/polyrhythmic research with emotionality (with the „theconsistencyofdestruction“) and performative elements (w. in this exhibition i will show paintings from my time in basel (at the stiftung bartels) and berlin, that represent my emotions in times of great personal changes.Īnxiety, dealing with my own toxic masculinity, lack of feelings of belonging in the working scene, overload, a heart-muscle soreness disease and basically the questioning of every element in my life led to a depression and complete social isolation. Most of y’all probably know me as a trumpet player and composer (for the wdr bigband, pascal klewer bigband, 222 festival etc). From 9th to the 11th of october i will for the first time publicly show my art (paintings, light installations, videos, music) in the gallery „bunkerk101“ in the körnerstraße 101 in ehrenfeld, köln under the title now i get why people kill themselves ![]()
