(a)
Explanation of Solution
Given: The values of the variable termed ‘number’ are 30 and 35, and the following expression:
if (number % 2 == 0)
cout << number << " is even." << endl;
cout << number << " is odd." << endl;
To find: The possible output of the code.
Solution:
When the value of the number is 30.
The possible outputs of the code can be “30 is even� and “30 is odd�. The condition in the ‘if’ statement will be true because (30 % 2 == 0) will be true. Therefore, the ‘if’ statement will be executed, and it will print the message “30 is even� on the console screen. After that, the third statement will also be executed because it is not written in any ‘if or else’ block...

Using Semaphores for synchronization, implement a multithreaded cook that performs the following recipe, with each task being contained in a single Thread: 1. Task 1: Cut onions. a. Waits for none. b. Signals Task 4 2. Task 2: Mince meat. a. Waits for none b. Signals Task 4 3. Task 3: Slice aubergines. a. Waits for none b. Signals Task 6 4. Task 4: Make sauce. a. Waits for Task 1, and 2 b. Signals Task 6 5. Task 5: Finished Bechamel. a. Waits for none b. Signals Task 7 6. Task 6: Layout the layers. a. Waits for Task 3, and 4 b. Signals Task 7 7.

Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1. Request for a contiguous block of memory 2. Release of a contiguous block of memory 3. Compact unused holes of memory into one single block 4.…arrow_forward
