Parallel arrays: Arrays are used to group related data types together. The elements in two arrays with different variables that are related to their position are known as parallel arrays. Establishing relationship between two parallel arrays: Consider two arrays named “strMonth []” and “intBonus []” arrays are declared as follows: string strMonth[] = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"}; int intBonus[] = {25000, 26000, 27000, 29000, 31000, 34000, 36000, 37000, 38000, 40000, 41000, 45000}; Based on the above example, the relationship is established by using the same subscript for both the arrays. “strMonth[index]” have relationship on “intBonus[index]”. That is, the bonus amount of January month is 25000, February month is 26000, and so on.

Question

Program Plan Intro

Parallel arrays:

Arrays are used to group related data types together. The elements in two arrays with different variables that are related to their position are known as parallel arrays.

Establishing relationship between two parallel arrays:

Consider two arrays named “strMonth []” and “intBonus []” arrays are declared as follows:

string strMonth[] = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"};

int intBonus[] = {25000, 26000, 27000, 29000, 31000, 34000, 36000, 37000, 38000, 40000, 41000, 45000};

Based on the above example, the relationship is established by using the same subscript for both the arrays. “strMonth[index]” have relationship on “intBonus[index]”. That is, the bonus amount of January month is 25000, February month is 26000, and so on.

In C++Monkey Business A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 × 5 array, where each row represents a different monkey, and each column represents a different day of the week. The program should first have the user input the data for each monkey. Then, it should create a report that includes the following information: Average amount of food eaten per day by the whole family of monkeys. The least amount of food eaten during the week by any one monkey. The greatest amount of food eaten during the week by any one monkey. Write functions: average() least() greatest() main()

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.…
