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
- Final review ch6-7 C language Using arrays create a personal phone directory that contains room for first names and phone numbers for 20 people. Using the "names.txt" retrieve the first name and phone number for each person and store in arrays (parallel). Prompt the user for a name, search for the name, and if name is found in the array, display the corresponding phone number. If the name is not found, prompt the user to enter a phone number, and add the new name and phone number to the list. Continue to prompt the user for names until the user enters quit or until arrays are full. After the arrays are full (containing 20 names), do not allow the user to add new entries.

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_forward

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 a ship. This file is the battleship game board. An example file might look like: Then write a C++ program that will read in the file representing the game board with 25 lines where each line has 25 characters corresponding to the description…arrow_forward
- CorrectFormation Create a program and locally declare in main fname and Iname and completeName. Ask the user for their first and last name. Put the values into fname and Iname. You will create a function that is called as followed. joinNames( fname, Iname, completeName ); You will pass the first name array, the last name array, and the array that will contain the complete name. The function named joinNames should put the first and last names together in completeName. Make sure that the first and last names begin with capital letters, and that ll others are lower case.
