Problem 2: Create a ticket spin lock Complete the functions in ticket_spin_lock.cpp to implement a ticket lock that spins while waiting. Some useful hints: • The lock_t* lock struct containts the variables int ticket and int turn. • Use the atomic function_sync_fetch_and_add( int* ticket, int addition ). This function will atomically fetch the value in ticket and add addition to this value. • You may not need to do anything in the destroy function.
