FHTW Berlin Fachbereich 4 Internationale Medieninformatik PROG2: Programmierung II Sommersemester 2003

Solutions to Exercise 1

The first finger exercise was not about filling an array with characters - it was how to access an array (for example, one that counts characters. So instead of being able to do count[currentCharacter]++ we have to convert the character to a number, perhaps normalizing it by subtracting the value for a capital A from the value so obtained.

Normalization is converting to a normal form, for example in Strings making the string into UpperCase so that A and a are the same letter.

You should have discovered that inserting a row or deleting a column is difficult with an Array but easy using a Vector.

• Katja and Lars have a nice description of "Einfügen und Löschen von Reihen in einer Matrix". In "Rekapitulation des Pre-Lab" they also have a nice picture of a Matrix as an Array of Arrays. They have a nice Matrix implementation and they also do a "Star-Histogram"!
• Steffi and Hans have some nice test cases for their Matrix!
• Susanne and Stefan found a use for David's LittleDebugger for displaying the histogram!
• Tilman and Andreas also have a nice solution for the stars.
• Frank and Andreas were so bored that they also did the vertical bars for the histogram. Check it out!
• Doris and Ralf put their "star maker" in a method that will at least make it easy to scale to a particular window size.
• Also have reports from Susanne and Jorgen - Volker and Jeanette - Birol - Mariam and Jana - Markus and Daniel - Gregor and Jenny - Denis -
