(Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().

IN C# Q. Lucky Number Definition:● A lucky number is a number whose value is equal to the occurrence of that number in anarray.○ [2, 2, 3, 3] => 2● If there is more than one number whose value is equal to the occurrence of that numberin an array, then the lucky number will be the one with the maximum value among alllucky numbers.○ [1, 2, 2, 3, 3, 3, 4] => 3● If there is no number in an array whose value is equal to the occurrence of that numberin the array then the lucky number will be -1.○ [5] => -1Implement a function getLuckyNumber(numbers) that takes an array of positive integers asinput and returns the lucky number from the array.Test Cases:● getLuckyNumber([2, 2, 3, 3]) => 2● getLuckyNumber([1, 2, 2, 3, 3, 3, 4]) => 3● getLuckyNumber([5]) => -1getLuckyNumber(numbers){// function implementation// return number whose value is equal to the occurrence of the number in the array// e.g [2, 2, 3, 3] => lucky number = 2// in case there are multiple lucky numbers…
Input Parameters: sea: an array of integers indices': an array of integers (each of which may or may not be a valid index for sea") Assumptions: sea may be empty. indices may be empty. *indices may contain duplicates. What to return? - For each integer value in 'indices', if it is a valid index for input array ssa', then use it to index into 'sea' and include the result in the output array. For example: Say ssa' is (23, 46, 69} and indices' is (2, -1, 0, 3, 0, 2} (where indices -1 and 3 are invalid, so only indices 2, 0, 0, 2 are used) Then the method should return (69, 23, 23, 69} Note: Order of elements in the output array corresponds to the order in which valid indices in the 'indices' array are arranged. That is, the output array may be empty if the input array sea is empty, or if the input array indices does not contain any valid indices. See the JUnit tests related to this method. */ public static int () task1(int ) seq, int () indices) { int (] result - null; return result;

Then let the teacher fill the array by students IDs and courses marks for each student. And print the following: 1- Print the array. 2- Print the marks that are less than 50 (mark < 50)
Task 3: Statistics using arrays: by java programming With the spread of COVID 19, the HR department in a company has decided to conduct some statistics among the employees in order to determine the number of infections according to some conditions. For each employee, they have to record the code, name, age, whether he/she was infected or no and the remaining days of leaves for him/her. You are requested to write the program that maintains the lists of details for the employees as mentioned above using the concept of arrays. The program repeats the display of a menu of services until the user decides to exit. 1. Start by initializing the employee details by reading them from the keyboard. 2. Repeat the display of a menu of 4 services, perform the required task according to the user’s choice and asks the user whether he/she wants to repeat or no. You need to choose one service from each category (‘A’,’B’,’C’,’D’) a. A. Display the total number of employees that were infected b. B.…

X482: Make Perfect Array The mere presence of oversized arrays makes Priscilla Perfect sick to her stomach. Such wasted space is an imperfection she cannot bear. As her oldest and dearest friend this worries you greatly. If you were a doctor you might try to find a cure to her sickness, but you are a programmer. A program must be written to alleviate her pain! For any array given that has empty slots create a new array that is perfect. Unused slots will have a value of 0. All unused slots are guaranteed to be at the end of the array. There will never be unused slots in the middle. java.util.Arrays has been enabled. Examples: makePerfect({1, 1, 4, 5, 6, 0, e, e, 0}) -> {1, 1, 4, 5, 6} makePerfect({1, 3, 4, 2, 6, 0, e, e, 0}) -> {1, 3, 4, 2, 6}

Programming: Multi-Array Assignment Instructions Overview Using a two-dimensional array, you will create the game battleship using a text file that contains the board. The user will enter coordinates to try and find ships and sink them. Instructions Imagine you are using a two-dimensional array as the basis for creating the game battleship. In the game of battleship, a `~' character entry in the array represents ocean (i.e., not a ship), a `#' character represents a place in the ocean where part of a ship is present, and a `H' character represents a place in the ocean where part of a ship is present and has been hit by a torpedo. Thus, a ship with all `H' characters means the ship has been sunk. Declare a two-dimensional array that is 25 x 25 that represents the entire ocean and an If statement that prints "HIT" if a torpedo hits a ship given the coordinates X and Y. Create a text file of 25 line. Each line has 25 characters. ~ represents water and # represents part of…
