Consider the following implementation of a container that will be used in a concurrent environment. The container is supposed to be used like an indexed array, but provide thread-safe access to elements.
struct concurrent_container { // Assume it’s called for any new instance soon before it’s ever used void concurrent_container() { init_mutex(&lock); }
~concurrent_container() { destroy_mutex(&lock); }
// Returns element by its index. int get(int index) { lock.acquire(); if (index < 0 || index >= size) { return -1; }
int result = data[index]; lock.release(); return result; }
// Sets element by its index. void set(int index, int value) { lock.acquire(); if (index < 0 || index >= size) { resize(size); } data[index] = value; lock.release(); }
// Extend maximum capacity of the…
Write a C program using embedded assembler in which you use your own function to multiply by two without using the product.
Tip: Just remember that multiplying by two in binary means shifting the number one place to the left. You can use the sample program from the previous exercise as a basis, which increments a variable. Just replace the INC instruction with SHL.

- Answer the Java OOP question below: Explain the relationship between a superclass and a subclass. How do the principles of encapsulation and abstraction play a role in this relationship? In your experience, how do you decide what should be included in a superclass versus a subclass?
