Algorithms and Data Structures Dr. Andreas Nüchter September 29, 2009 284 Data Structures A Java/C/Pascal/… program is composed of an algorithmic part (the instructions) that describe, how the stored data is manipulated and a declaration part that contains the structure of the data. Niklaus Wirth (the inventor of Modula and Pascal) used the following formula: Now: Lets look at data structures and (abstract) data types
Algorithms and Data Structures Dr. Andreas Nüchter September 29, 2009 285 Data Structures Roughly spoken data structures are the construction of the co-domain from the variable used by a program. These co-domains are constructed from the co- domains of elementary data types (e.g. int , float , char ) using so-called constructors . From the math point of view they are: Cartesian products (array, record) Disjoint union (variant record) Recursion (pointer) Power sets (set of)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
