In lecture today, we covered the following topics:
- an overview of the GDB gnu-debugging tool. A short manual of the basic keywords/functionality has been added to the left hand toolbar.
- Discussion of the notion of char* C-strings (char arrays ended with a null character ‘\0’)
- Writing two functions that deal with C-strings - string length (strlen) and string equal
- Noting the useful idea - when dealing with memory-addressed data, a fast easy first check for equality is to test whether the pointers are pointing to the same place.
Example programs we saw:
- nullTerminatedCharArray.cpp (example programs to work with null terminated char arrays as strings - includes a length and an equals function; multiple version of the functions are in the file, including some of the ones we arrived at on the board in class today)
