- Write a java program that specifies three parallel one dimensional arrays name length, width, and area. Each array should be capable of holding a number elements provided by user input. Using a for loop input values for length and width arrays. The entries in the area arrays should be the corresponding values in the length and width arrays (thus, area[i] = length [i]* width [i]) after data has been entered display the following output: Length Width Area -------- -------- ------- 25 2.6 65.00 18.2 4.9 89.18 Sample Run1 Enter the array size: 5 Enter the Length and Width for Rectangle 1: 25 2.6 Enter the Length and Width for Rectangle 2: 18 4.9 Enter the Length and Width for Rectangle 3: 100 3.27 Enter the Length and Width for Rectangle 4: 1.84 7.4 Enter the Length and Width for Rectangle 5: 56 9.5 Output1: Length Width Area -------- --------…Code language Java 1, Add a print statement to say “Multiplication Table” and then prompt theuser to enter an integer. Your program should then prints “times table” for thenumbers from 1 to the given integer (inclusive). That is, for input n, you would printa table of n rows (lines) each with n columns, where the cell at row i and columnj contains the value i × j. You do need separate rows, but don’t worry about thecolumns lining up nicely yet. 2. Add a print statement to say “Prime Testing”.Using the integer entered by the user above, print out all the prime numbers between2 and the number squared. E.g., if the user types 12 for the multiplication table part,you should print all the prime numbers that are not larger than 144.All integers are either prime or composite. A prime number is one that has no integerfactors other than itself or one. Examples are 2, 3, 5, 7, 11, 13, . . .. A compositenumber, by contrast, has multiple factors. Examples are 4, 6, 12, 15, 18, 21, . . ..Testing…2-D Array Using only one 2-D array (table) with equal odd sizes for its rows and columns, write a complete java program for a magic square.

Input: Enter size = 3 Output: 3 x 3 magic square 8 1 6 3 5 7 4 9 2 Note: All rows, columns, and diagonal sum = 15 Try again (Y/N) Y Input: Enter size = 5 Output: 5 x 5 magic square 17 24 1 8 15 23 5 7 14 16 4 6 13 20 22 10 12 19 21 3 11 18 25 2 9 Note: All rows, columns, and diagonal sum = 65 Try again (Y/N) N

The value of a word is the sum of each tile's points added to any points provided by the word's placement on the game board. Write a program using the given dictionary of letters and point values that takes a word as input and outputs the base total value of the word (before being put onto a board). Ex: If the input is: PYTHON the output is: 14 tile_dict = { 'A': 1, 'B': 3, 'C': 3, 'D': 2, 'E': 1, 'F': 4, 'G': 2, 'H': 4, 'I': 1, 'J': 8, 'K': 5, 'L': 1, 'M': 3, 'N': 1, 'O': 1, 'P': 3, 'Q': 10, 'R': 1, 'S': 1, 'T': 1, 'U': 1, 'V': 4, 'W': 4, 'X': 8, 'Y': 4, 'Z': 10 } ''' Type your code here.

- Write a program named as reverse.c that reads a message, then prints the reversal of the message. The output of the program should look like this: Enter a message: Don ’t get mad, get even. Reversal is : .neve teg ,dam teg t ’noD Hint: Read the message one character at a time (using getchar) and store the characters in an array. Stop Reading when the array is full or the character read is ‘\n’. The framework of reverse.c is as below: /* reverse.c */ #include #define N 50 int main(){ int arr[N],i=0; char ch; printf("Enter a message: "); /* Put code here to get input from user by using getchar() */ printf("Reversal is: "); /* Put code here to print out the reversal by using putchar()*/ printf("\n"); return 0; }2. JAVA Programming Arrays a1, a2… are populated as shown; display a[i] for each calls to arr; if a[i] less than or equal to 0 display a message indicating those conditions public static void arr(int[] a) { //Add the missing loop a[i] = a[i + 1] + a[i - 1]; // display a[i] } } a1 = 3, 7 a2 = 4, 7, 4, 2, 10, 9 a3 = 1, 5, 0, 0, 5, 0 a4 = 13, 0, -4, -2, 0, -1 a5 = 2, 4, 6, 8, 16The statement int *p;declares p to be a(n) [l1] . p will store an integer value p will store the address of an integer variable p will store the result of multiplication of two integers p will store the address of a variable of any type
- CODE IN JAVA design a program that grades arithmetic quizzes as follows: (Use the below startup code for Quizzes.java and provide code as indicated by the comments) 1. Ask the user how many questions are in the quiz. 2. Use a for loop to load the array. Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34, 7, 13, 100, 8 might be the key for a 5-question quiz. You will need to store the key in an array called "key". 3. Ask the user to enter the student's answers for the quiz to be graded. There needs to be one answer for each question. Note that each answer can simply be compared to the key as it is entered. If the answer is correct, add 1 to a correct answer counter. need this in a separate for loop from the loop used to load the array. 4. When the user has entered all of the answers to be graded, print the number correct…Interestingly some numbers can be perfectly represented in Base 10, but not in Base 2. An example is one-tenth (in Base 10, this is 0.1; in Base 2 this is a repeating decimal. Suppose we set both f and g to one-tenth using the statements below. f = 0.1; g = 0.1; Answer the following questions. For each, mark the best answer. Which will be closer to the actual value of one-tenth? f g Which can hold higher values? f g Which takes more memory? f g When using real values I should always use type double, to be safe. True FalseAssignment for Computer Architecture You are to write a program in MIPS that computes N! using recursion. Remember N! is the product of all the numbers from 1 to N inclusive, that is 1 x 2 x 3 x (N – 1) x N. It is defined as 1 for N = 0 and is undefined for values less than 0. The programs first requests the user to input the value of N (display a prompt first so the user knows what to do). If the input value is less than 0, the program is to display “N! undefined for values less than 0” and then requests the user to input the value of N again. If the value input is non-negative, it is to compute N! using a recursive function, that is one that calls itself. You are to have your name, the assignment number, and a brief description of the program in comments at the top of your program. Since this is an assembly language program, I expect to see comments on almost every line of code in the program. Also make the code neat: line up the command fields, the register fields, and the comment…
