- (Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().arrow_forward(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.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
- (Numerical) Write and test a function that returns the position of the largest and smallest values in an array of double-precision numbers.arrow_forwardC++ LANGUAGE Search Metrics In this exercise you will explore the performance difference between sequential search and binary search. To do so write a program that performs the following tasks: Prompt the user for a file containing 100,000 unsorted integers Read those integers into an array Prompt the user for a search item Search for that item (using sequential search) and report the number of comparisons required. Sort the array. Note that this might take a few minutes. Search for that item again (using binary search) and report the number of comparisons required. You will need to modify both of the search functions to report the number of comparisons that were made during the search. Use your program and the file of 100,000 integers provided here to answer the six questions in the quiz. May i know whats the program please?arrow_forwardMovie Data Write a program that will be used to gather statistical data about the number of movies college students see in a month. The program should ask the user how many students were surveyed and dynamically allocate an array of that size. The program then should allow the user to enter the number of movies each student has seen. It should then sort the scores and calculate the average. Modularity: Main: The main function should accept the number of students from the user and dynamically create an array large enough to contain number of movies watched for each student. Input validation: The number of students should be a positive integer. Print the average and free the allocated array when complete. Get the data: This function should get the number of movies watched by each college student. Input validation: The number of movies should be a positive integer. Sort the data: This function should sort the array in ascending order. Note you may use the Standard Template Library sort…arrow_forward
- C++ Visual 2019 Write a program that uses a two identical arrays of at least 100 randomly generated integers. It should call a function that uses the bubble sort algorithm to sort one of the arrays in ascending order. The function should keep a count of the number of exchanges it makes. The program then should call a function that uses the selection sort algorithm to sort the other array. It should also keep count of the number of exchanges it makes. Display these values on the screen with appropriate descriptions.arrow_forwardPROGRAMMING LANGUAGE: C++ Write a program that accepts up to 20 test-match scores of a batsman in the range of 0 to 100 from the user and stores them in an array. Then main should report how many perfect scores (i.e., scores of 100) and ducks (i.e., scores of 0) were enteredarrow_forwardC programming using Arraysarrow_forward
- Sorting is a basic issue with arrays in which the goal is to find the target element in the array. Choose from the following options: Falsearrow_forwardTask 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.…arrow_forwardC++ programming language please use <iostream> Please include explanations when writing the program using //arrow_forward
