A hash table is an array of items, which are { key: value } pairs. First, define the item structure: HashTable.cpp. // Defines the HashTable item. typedef struct Ht_item { char* key; char* value; } Ht_item; Now, the hash table has an array of pointers that point to Ht_item, so it is a double-pointer. HashTable.cpp.

Example explained. Statement 1 sets a variable before the loop starts (int i = 0). Statement 2 defines the condition for the loop to run (i must be less than 5). If the condition is true, the loop will start over again, if it is false, the loop will end. Statement 3 increases a value (i++) each time the code block in the loop has been executed.Graduates of coding bootcamps are gaining on computer science majors—just one example of how the working world is undergoing its biggest change in generations.
