- (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(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(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 declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().arrow_forward(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
- (Numerical) Given a one-dimensional array of integer numbers, write and test a function that displays the array elements in reverse order.arrow_forwardUse C++ programing language Write a modular program that analyzes a year’s worth of rainfall data. In addition to main, the program should have a getData function that accepts the total rainfall for each of 12 months from the user and stores it in an array holding double numbers. It should also have four value-returning functions that compute and return to main the totalRainfall, averageRainfall, driestMonth, and wettestMonth. These last two functions return the number of the month with the lowest and highest rainfall amounts, not the amount of rain that fell those months. Notice that this month number can be used to obtain the amount of rain that fell those months. This information should be used either by main or by a displayReport function called by main to print a summary rainfall report similar to the following: 2019 Rain Report for Springdale County Total rainfall: 23.19 inches Average monthly rainfall: 1.93 inchesarrow_forwardPointers reduce the length and complexity of programs. Demonstrate a program to find a maximum and minimum element from an array by passing an array into a function using a pointer.arrow_forward
- 3. Pointers – Arrays: initializing content • Using the pointer ptrArray, you now want to write values in those integers. Use a loop to go through each element in that array, and initialize them all to 42. This is done in the main. 4. Pointers – Arrays: printing • Write a function that will print the elements in the array-pointer. The function should accept a pointer to an integer, and the size of this array. The function should not return anything. Here is your function prototype: void printArray(int* ptr, int nb); • Your function needs to use a loop to go through all the elements in the array, and simply prints them on a new line. • In the main function, call this function with your pointer ptrArray and the size given by the user.arrow_forward""" HouseholdSize.py - This program uses a bubble sort to arrange household sizes in descending order and then prints the mean and median household size. Input: Interactive. Output: Mean and median household size. """ # Initialize variables. householdSizes = [] # Array used to store household sizes. numSizes = 0 total = 0.0 mean = 0.0 median = 0.0 # Input household size householdSizeString = input("Enter household size or 999 to quit: ") householdSize = int(householdSizeString) # This is the work done in the fillArray() function while (householdSize != 999): # Place value in array. householdSizes.append(householdSize) # Calculate total of household sizes numSizes += 1 # We have one more house householdSizeString = input("Enter household size or 999 to quit: ") householdSize = int(householdSizeString) # Find the mean # This is the work done in the sortArray() function # This is the work done in the displayArray()…arrow_forwardIn c++, write a function countletters that counts the number of times a particular letter occurs in an array. The function should have three arguments: the array that holds the characters; the letter you are searching for; and the number of characters in the array. It should return a count.arrow_forward
