Initial-git, Aufgabenstellung, Belegdaten
Backup with extension of thoughts. First programming can begin, presumably on 01.05.2013
First attempt, copy of dev_field, open_and_read() works, needs malloc() and free()
Deleted unused dev_field-stuff
open_and_read() now scanning line by line instead of char by char, still needs dynamic memory allocation, see malloc_kram(), get it to work!
Counting rows, too! Found a nice example of malloc() to go alling with strtok(), should definitely implement!
open_and_read() changed to count not only the lines, but now also the rows. Needed for assigning an array to work with the extracted int's
Implemented malloc(), works like a charm. Using file_name_create() to generate filenames, passed to open_and_read().
Slightly extended thoughts. Different *.dat-size have to bea handeled.
Now establishing the min_~ and max_column_value, needed for dimensioning value_array.
make_array() functionable, need to make it return the pointer to the array
2D-Arrays working, neet to run make_array() ONCE in the working-funktion, and then speparately work through the files with a while-loop in the working-function
passing of 2D-Array almost works, need to figure out how to use its pointer is passend over to a function
Fixed a severe bug in dimensioning the array. In open_and_copy_in_array(): Fill the array with values and let the calculations begin! Also: Check the later mentioned SO-Link to free() the complete array
make_array() working, open_and_copy_in_array() working. Array is correctly built. Next step: implementing calculations
Changed the returns to not be errors anymore
Added second make_array(), filling everything with 0's. Added Histogramm(), mittlere_Hoehe(). Works quite well. Every calculation-task is handeled. Just needs to generate output, and conversion for Windows-OS's.
Added preprocessor-directives for debugging; #define DEBUG and #ifdef DEBUG [...] #endif
html-output outsourced to outputc for testing purposes. Works well, needs implementation of CCS.
Added CSS-File, works great! Output tables can now be generated!
