4.1.4 dict_put It is now time for: void dict_put (dict_t* dict, const char* key, const char* val); This function stores the pair key/val in the dictionary dict, possibly erasing the previous value associated with key. It should make private copies of key and val as required. This means that the function cannot use, for instance, my_element->val = val. To make a copy of a string s, one could: 1. allocate strlen(s) + 1 bytes using malloc(3) (strlen(3) returns the length of a string, not counting the end-of-string marker) 2. go through the strlen(s) + 1 bytes of s and copy each byte, using either a loop or the function memcpy(3) Again, the standard library provides a function for this: strdup (3)-remember that since its return value was malloc'd, it needs to be free'd. The function works as follows: •If key is found in dict, then the associated value should be freed and replaced by a copy of val. If key is not found in dict, then a new element is added to the list; that element's key is a…

The anchor from Part A can also fail in shear in the circular head, as shown (Figure 3). What is the minimum thickness tt required for the head to support the allowed load PallowPallow = 15 kNkN if the material fails in shear at τfailτfail = 30 MPaMPa ? Use a factor of safety F.S.F.S. = 2.2.

4.1.2 dict_create Equipped with these structures, start by implementing: dict_t* dict_create (); This function should allocate a new structure of type dict_t (aka struct dict), initialize its members, and return the newly allocated structure. To do so, you will call malloc to allocate a sufficient amount of memory: dict t* ret malloc (sizeof (dict_t)); Then, you should initialize the fields of ret. Since ret is a pointer, to access the object it points to, you should use *ret; hence the size field is accessed using (*ret).size. C has a shorthand notation for this very common construct: ret->size = 0; Now make sure to initialize head (since its value is garbage as it was just allocated) and you are done and can return ret. You will be implementing dict_destroy in Part 2; this is the function that will be in charge of freeing the memory that was just allocated: in C, memory that is malloc'd is never automatically freed. Memory allocation is the topic of Ch. 9. 4.1.3 dict_get Next, you…
