Consider the following code: int x = 0x2020; int *y = &x; int **z = &y; *y += 8; int w = **z; Suppose the compiler puts x at address 0x2000, y at address 0x2008, z at address 0x2010, and w at address 0x2018. Use this code to answer the next questions. What value is in y after the code above runs? A. 0x2000 B. 0x2008 C. 0x2010 D. 0x2018 E. 0x2020 F. 0x2028 G. 0x2030 What value is in z after the code above runs? A. 0x2000 B. 0x2008 C. 0x2010 D. 0x2018 E. 0x2020 F. 0x2028 G. 0x2030 What value is in w after the code above runs? A. 0x2000 B. 0x2008 C. 0x2010 D. 0x2018 E. 0x2020 F. 0x2028 G. 0x2030

4. Implement a function fst(int, int) that takes two integers as parameters and returns the number of common bits in the binary of both the numbers. Language: Java

Part1: Java Programming Without using function 1. Write a program that reads in an integer and breaks it into a sequence of individual digits. For example, the input 16384 is displayed as 1 6 3 8 4

Write in Java: Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is: As long as x is greater than 0       Output x % 2 (remainder is either 0 or 1)       x = x / 2 Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string. Ex: If the input is: 6 the output is: 110 Your program must define and call the following two methods. The method integerToReverseBinary() should return a string of 1's and 0's representing the integer in binary (in reverse). The method reverseString() should return a string representing the input string in reverse. public static String integerToReverseBinary(int integerValue)public static String reverseString(String inputString) LabProgram.java: import java.util.Scanner; public class LabProgram {/* Define your method here */ public static void main(String[] args) {/* Type your code…

Given the following C code: int a[10] = {0,1,2,3,4,5,6,7,8,9};int *m = &a[0];int *p = &a[5];int *q = &a[1]; p = (int) m + (int) p - (int) q;    What is the value of *p?

Develop a C++ program to calculate the area, perimeter and diagonal of a rectangle. The program should also offer the option to display the rectangle. The main flow of the program is given as follows: The user should input the length and width of a rectangle. The user can decide to display the drawing of the rectangle or not. If user indicate yes, execute user's decision. Display the calculated area, perimeter and diagonal of the rectangle. The program should repeatedly ask if the user wants to process another rectan- gle. Your program should include two functions with the following function prototypes: void drawRec(int length, int width); A function that display a full rectangle with '+'. void calcRec (int a, int b, int *area, int *perim, float *diag); A function that returns the area, perimeter and diagonal through pointer parame- ter. Sample output:

Write a C++ program that takes an char array of size twenty. Take input a sorted array from the user. Display the char array on console such that each row has only five elements separated by spaces. Then, you are required to then take a char x from the user and use binary search to search for element x in the array. Display the index of the element on the console. Also display two elements before and after the element x. Note: Don't use functions and strings.

In C++, there is an equation, please read this problem carefully. 2. Write a program to declare an integer array A of size 5 and assign its content (elements) through user input from the screen. Then call a function called "Max" that will calculate z using the equation given below and return and print the value of z from the main function. Note that you can call the function and return the z value using the call-by-reference or call-by-value method. z=4. Σε 14.

7. We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different "digits" {0,1,.9). Sometimes though it is useful to write numbers in hexadecimal or base 16. Now there are 16 distinct digits that can be used to form numbers: {0,1,..,9,A,B,C,D,E,F}. So, for example, a 3 digit hexadecimal number might be 3B8. (a) How many 2-digit hexadecimals are there in which the first digit is E or F? Explain your answer in terms of the additive principle (using either events or sets). (b) Explain why your answer to the previous part is correct in terms of the multiplicative principle (using either events or sets). Why do both the additive and multiplicative principles give you the same answer? (c) How many 3-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)? Explain. (d) How many 3-digit hexadecimals start with a letter (A-F) or end with a numeral (0-9) (or both)? Explain.
