If cell 5 in memory has the value 8, what is the functional difference between writing the value 5 into cell 6 and copying the contents of cell 5 into cell 6?
Step by step
Solved in 2 steps
- 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…What is the correct way to assign the pointer p to the address of x?. Single choice. p = %x; p = &x; &p = *x; *p = &x;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)
- Perform the given task.Problem Y: Implement the reader writer problem using pthreads and semaphores. You should allow multiple readers to read at the same time and only one single writer to write to the data set. You are required to use the following: 1. A semaphore rw_muter initialized to 1. 2. A semaphore muter initialized to 1. 3. An integer reader_count initialized to 0.Part 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…
- 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?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? Use your program to verify your answer #include <stdio.h>int main( ) { char c = ‘Z’; char *cp = &c; printf("cp is 0x%08x\n", cp); printf("The character…Write these in Pseudocode #1a – In pseudocode, write a call to a function that passes 1 Integer variable and 1 Integer array, and saves a Boolean value in return. #1b – In pseudocode, write the function that accepts 1 Integer and 1 Integer array and returns a Boolean. In the function, search the Integer array with a for-loop, and if the Integer parameter is found in the array, return false. If the Integer parameter is not found, return true. #2a – In pseudocode, write a call to a module that passes 1 Integer variable, 1 Real variable, 1 String constant, and 1 String literal as arguments. #2b – In pseudocode, write the module header that accepts 1 Integer, 1 Real, and 2 Strings as parameters. #3 – This pseudocode has multiple problems. Fix the calling statement and the definition below so that the routine accepts 3 grades as parameters and returns the average into a variable.…
- Write a complete program in x86 assembly language with irvine package that: 1. Prompt the user to enter 10 numbers. 2. save those numbers in a 32-bit integer array. 3. Print the array with the same order it was entered. 3. Calculate the sum of the numbers and display it. 4. Calculate the mean of the array and display it. 5. Rotate the members in the array forward one position for 9 times. so the last rotation will display the array in reversed order. 6. Print the array after each rotation. check the sample run. ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Don't use any shift or rotate instructions which we have not coveredyet. You need to use loops and any kind of addressing. All you work should be on the original array. Don't make a copy of the array at any time. Add comments to make your program easy to read.
