- analyzing the ethical and societal challenges of self-driving vehicles. Refer back to the syllabus and utilize the Case Study requirements that explain expectations in length and in content. Consider who should be held responsible in the event of an accident, given the "problem of many hands" in technology development. Discuss how autonomous vehicles might approach moral dilemmas in unavoidable accident scenarios and what ethical principles should guide these decisions. Lastly, reflect on how self-driving vehicles might impact behavior and societal norms around road safety.

- 6.2 User interface (main.c) You will be using files for saving and loading dictionaries. For this, we will use the standard library, in which the "file object" is a pointer to a structure that you manipulate using some functions. This follows the pattern we've been using for the dictionary library: users do not know what is in that structure and only access it through an interface. 6.2.1 dmp This command does not manipulate files; it simply dumps the dictionary to the standard output. It should start by printing BEGIN_DUMP, then all the pairs key: value separated by newlines, then END_DUMP: > put abc:def > put 123:456 > dmp BEGIN DUMP abc:def 123:456 END_DUMP > To implement this, refer to the example file print.c in Section dict apply. The order in which the elements are printed is not important (it depends on how you implemented your dictionary).arrow_forwardI don't know how to solve thisarrow_forwardneed helparrow_forward
