Chapter 1.2, Problem 2QE
Explanation of Solution
Given Steps:
- Step 1:
- Move the contents of cell number 2 to cell number 3.
- Step 2:
- Move the contents of cell number 3 to cell number 2.
Errors in given sequence of steps:
- The Step 1 moves the contents of cell number 2 to 3.
- It deletes the value in cell number 2 and is been copied into cell number 3.
- The Step 2 moves contents of cell number 3 to cell number 2.
- It moves the value in cell number 3 to 2.
- In this case, the old value of cell number 2 only will get copied in this case.
- To rectify this, a cell is to be considered for temporary storage, suppose the cell is cell 4...

Let's assume the number 8 is stored in memory location 5. What's the difference between copying the contents of cell 5 into cell 6 and typing the value 5 into cell 6?
Numbers between 0 and 15 are stored in the memory location starting from physical address B000Fh randomly. Write a program which finds the element order number in the string starting from 0 to 15 and writes to physical address C000Fh. (Eg: "1" is 2nd element in the first string, "2" is 4th element, ....etc)
Write a program that will take n floating point numbers as input and print the sum, average and maximum of the numbers. Use dynamic memory allocation and pointers to do the task. Sample input file: 5 12 24 34 45 56 Sample output file: Sum : 171.0 Average : 34.2 Maximum : 56

- A common memory matching game played by young children is to start with a deck of cards that contain identical pairs. For example, given six cards in the deck, two might be labeled 1, two labeled 2, and two labeled 3. The cards are shuffled and placed face down on the table. A player then selects two cards that are face down, turns them face up, and if the cards match, they are left face up. If the two cards do not match, they are returned to their original face down position. The game continues until all cards are face up. Write a program that plays the memory matching game. Use 16 cards that are laid out in a 4 4 square and are labeled with pairs of numbers from 1 to 8. Your program should allow the player to specify the cards that he or she would like to select through a coordinate system. For example, in the following layout: 1 2 3 4 1 8 * * * 2 * * * * 3 * 8 * * 4 * * * * all of the face down cards are indicated by *. The pairs of 8 that are face up are at coordinates (1,1) and…arrow_forwardPerform the given task.arrow_forward*Student information is being held in a data area, where each student record has the following format: The first nine bytes are the student number, held in ASCII The next byte is the course mark The next word is the section identifier 10009. There are well over three hundred such student records that have been loaded sequentially into memory starting at address $10000. The last record loaded is a dummy record with a section identifier of $FFFF, to show the end of the rècords.

- : A monochrome screen is stored as a single array of bytes, allowing eight consecutivepixels to be stored in one byte. The screen has width w, where w is divisible by 8 (that is, no byte willbe split across rows). The height of the screen, of course, can be derived from the length of the arrayand the width. Implement a function that draws a horizontal line from (xl, y) to (x2, y).The method signature should look something like:drawLine(byte[] screen, int width, int xl, int x2, int y)arrow_forwardPart 2: Binary Arithmetic One of the most common operations we perform on binary numbers (and all numbers) is addition. It can be cumbersome to convert your binary numbers to decimal just to add them and convert them back, so instead we will be learning how to add binary numbers directly. Binary addition works the same way as decimal addition, with the added restriction that each digit can only go up to 1. Let's consider the possibilities for adding the values of any 2 single digits together: 0 + 0 0 + 1 1 + 0 1 + 1 0 1 1 10 (remember that 10 in binary represents the number 2) In that last case, the result is larger than a single digit. When adding larger binary numbers, that means we have to carry the 1 over to the next column. This presents us with another new case: what happens if we have 1 + 1 + carried 1? In that case, the result is 11, which means that column's result is 1, and we carry 1 to the next column. Below is an example of adding two binary numbers that shows all…arrow_forwardProblem Y: Implement the reader writer problem using pthreads and semaphores.

- 3. I/O Management: Disk Arm Scheduling & RAIDa. It is known that a disk drive has 256 cylinders, with cylinder numbers starting from 0 and ending at 255. The position of the needle on the disk drive currently stops at 128. It is also known that the needle always “goes to the cylinder with the smaller number first”. The order of the positions visited sequentially is: 254, 64, 32, 100, 50, 70. From the 3 choices of algorithms below, which one is the best algorithm? Make each image and determine the seektime.i.

The pointers we studied were mainly variables. O A pointer can be initialized with a special value called nullptr. In the material we studied, we saw that a pointer can contain an entire array. This definition: double * dp; means that the dp variable can contain a double. Assume this is a function heading for the code you will write: void somthing10 (int * ptr) a. In one line of code, how could you add 10 to what ptr points to? b. Assume ptr points to the first element in an array of ints, each of which takes up 4 bytes of memory in RAM. In one line of code, how could you store 10 into the third element in the array?

The second list should only contain uppercase letters. The third list should only contain numbers. Each list stored in the dictionary should be stored in ascending order. Use the following naming convention when creating your lists: numbers uppercase lowercase Make sure that you adhere to the above instruction, as the name of your lists will be used to mark your function. Arguments: character_list: (list) →→ list of alphanumeric characters. Return: dictionary (dict) →→ dictionary containing all three lists. Expected outputs lst = [2,'j','K','o',6,'x',5,'A',3.2] create_dictionary(lst) {'numbers': [2, 3.2, 5, 6], 'uppercase': ['A', 'K'], 'lowercase': ['j', 'o', 'x']}arrow_forward
- The program below uses pointer arithmetic to determine the size of a 'char' variable. By using pointer arithmetic we can find out the value of 'cp' and the value of 'cp+1'. Since cp is a pointer, this addition involves pointer arithmetic: adding one to a pointer makes the pointer point to the next element of the same type. For a pointer to a char, adding 1 really just means adding 1 to the address, but this is only because each char is 1 byte. Compile and run the program and see what it does. Write some code that does pointer arithmetic with a pointer to an int and determine how big an int is. Same idea – figure out how big a double is, by using pointer arithmetic and printing out the value of the pointer before and after adding 1. What should happen if you added 2 to the pointers from exercises 1 through 3, instead of 1?

Then, write another program named “oddeven.c” which will take some numbers from the command line, then check and print whether the numbers in the array are odd or even. Now, you have to write a program that will create a child process and the child process will first sort the array that you have declared in this program. And then, the parent process will print the odd/even status for each number in the array.arrow_forward
