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.…
1. Display Function
Implement a function to display the contents of the patient_list array.
Add code to call this function. Note that there are multiple places where this function needs to be called. Look for the // TODO comments to find the correct locations.
2. Sorting the array by Age
Implement the code to sort the contents of the patient_list array based on the value stored in the age field. To do this you will need to implement code that relies on the qsort function from the C Standard library
A function that compares two patient elements, based on the value stored in the age field.
A call to the qsort function, which includes the array to be sorted, the number of elements in the array, the size of each array element and the function used to compare the array elements.
Add code to call the qsort function, using the age comparison function that you implemented. This code should be placed just under the appropriate // TODO comment in main().
Sorting the array by…
The Problem: Matching Group Schedules
The group schedule matching takes two or more arrays as input. The arrays represent slots that are already booked and the login/logout time of group members. It outputs an array containing intervals of time when all members are available for a meeting for a minimum duration expected.
Sample Input
Enter person1_Schedule =[[ ‘7:00’, ’8:30’], [’12:00’, ’13:00’], [’16:00’, ’18:00’]]
person1_DailyAct = [‘9:00’, ’19:00’]
Enter person2_Schedule = [[ ‘9:00’, ’10:30’], [’12:20’, ’13:30’], [’14:00’, ’15:00’], [’16:00’, ’17:00’ ]]
person2_DailyAct = [‘9:00’, ’18: 30’]
Enter duration_of_meeting =30
Sample output
[[’10:30’, ’12:00’], [’15:00’, ’16:00’], [’18:00’, ’18:30’]]
Implementation
Have following files
Project1_starter.py or project1_starter.cpp that defines functions for the algorithm described above. You will need to develop and write the functions. Describe how to run your program in the ReadMe file

- (Statistics) a. Write a C++ program that reads a list of double-precision grades from the keyboard into an array named grade. The grades are to be counted as they’re read, and entry is to be terminated when a negative value has been entered. After all grades have been input, your program should find and display the sum and average of the grades. The grades should then be listed with an asterisk (*) placed in front of each grade that’s below the average. b. Extend the program written for Exercise 1a to display each grade and its letter equivalent, using the following scale: Between90and100=AGreaterthanorequalto80andlessthan90=BGreaterthanorequalto70andlessthan80=CGreaterthanorequalto60andlessthan70=DLessthan60=Farrow_forward(List maintenance) The following letters are stored in an alphabet array: B, J, K, M, S, and Z. Write and test a function named adlet(), which accepts the alphabet array and a new letter as arguments, and then inserts the new letter in the correct alphabetical order in the array.arrow_forward(Electrical eng.) Write a program that specifies three one-dimensional arrays named current, resistance, and volts. Each array should be capable of holding 10 elements. Using a for loop, input values for the current and resistance arrays. The entries in the volts array should be the product of the corresponding values in the current and resistance arrays (sovolts[i]=current[i]resistance[i]). After all the data has been entered, display the following output, with the appropriate value under each column heading: CurrentResistance Voltsarrow_forward
- Code in Perl Create an array which holds a list of Video Games, consisting of title, the year it was released (guess if you don’t know) , platform (NES, XBOX One, etc) and publisher (in that order). Add at least ten albums to the list. Then, use the split function and a for or foreach loop to display the publisher followed by the title and platform for each list element.arrow_forwardFinding the common members of two dynamic arrays: Write a program that first reads two arrays and then finds their common members (intersection). The program should first read an integer for the size of the array and then should create the two arrays dynamically (using new) and should read the numbers into array1 and array2 and then should find the common members and show it. Note: The list of the common members should be unique. That is no member should be listed more than once. Tip: A simple for loop is needed on one of the arrays (like array1) and one inner for loop for on array2. Then for each member of array1, if we find any matching member in array2, we record it. Sample run: Enter the number of elements of array 1: 7 Enter the elements of array 1: 10 12 13 10 14 15 12 Enter the number of elements of array 2: 5 Enter the elements of array 2: 17 12 10 19 12 The common members of array1 and array2 are: 12 10arrow_forwardModule/Week 8 ASSIGNMENTImagine you are using a two-dimensional array as the basis for creating the game battle- ship. 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.

First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen.
