In C#, __________ are enclosed in single quotation marks.
- a. strings
- b. enumerators
- c. tokens
- d. character literals

In C#, quotation marks are used to represent “character literals”.
Hence, the correct answer is option “D”.
Explanation of Solution
Character literals:
- • In C#, the data type named char is used to store single character.
- • The character literals are enclosed in quotation marks.
- • Example to declare and assign the char variable.
Char letter = ‘a’
Explanation for incorrect options:
String:
String value is enclosed in double quotation and gets stored in string data type.
Hence, the option “A” is wrong.
Enumerators:
enum keyword is used to represent an enumerator and identifiers are enclosed in braces.
Hence, the option “B” is wrong.
Tokens:
Tokens are also enclosed in double quotations and items of data are separated by space or other characters.
Hence, the option “C” is wrong.

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.

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
