- (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++ 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_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_forward
- C++ programming Write a program that uses a two identical arrays of at least 100 randomly generated integers.

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_forwardSearch Benchmarks Design an application in pseudocode that has an array of at least 20 integers. It should call a module that uses the sequential search algorithm to locate one of the values. The module should keep a count of the number of comparisons it makes until it finds the value. Then the program should call another module that uses the binary search algorithm to locate the same value. It should also keep a count of the number of comparisons it makes. Display these values on the screen.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_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_forward4- Using “Def” keyword write a function that returns the mean element of the given array elements (The function name will be MeanofArrayElements)5- Using “Def” keyword write a function that returns the sum of each element for the given array (The function name will be SumofArrayElements)6- Using “Def” keyword write a function that compares two arrays, if both are the same it will return true, else it will return false. (The function name will be AreArraysEqual)arrow_forwardC++ language Write a program that asks a user to input 10 numbers. The numbers are stored in the array if itis not Odd and not already available. After creating the array, it asks the user to enter a numberand deletes it from the array.arrow_forward
