- (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.C++ Write a function that accepts an array and its size as arguments, creates a new array that is a copy of the argument array, and returns a pointer to the new array. Display the array in main(). The function will work as follows: Accept an array and its size as arguments. Dynamically allocate a new array that is the same size as the argument array. Copy the elements of the argument array to the new array. Return a new pointer to the new array. // This program uses a function to duplicate// an int array of any size.#include <iostream>using namespace std;// Function prototype_________________________________________________int main(){ // Define constants for the array sizes. const int SIZE1 = 5, SIZE2 = 7, SIZE3 = 10; // Define three arrays of different sizes. int array1[SIZE1] = { 100, 200, 300, 400, 500 }; int array2[SIZE2] = { 10, 20, 30, 40, 50, 60, 70 }; int array3[SIZE3] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; // Define three pointers for the duplicate arrays. int *dup1 =…In c++, please and thank you! Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.
- 1. Write a function called void swap with two parameters, which will receive the addressof x and y as pointer. The function should swap the value of x and y only if x is larger thany. Print the value of x and y after the function call. 2. Write a function called double getAverage(int *array, int SIZE), whereit accept the array as pointer, and return the average of the array. Print the returnedvalue from this function. Always use *array rather than subscript to access the arrayvalue.In 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.C Program Functions using Pointers Create a function modify that accepts an integer and divides the integer by 2 if it is even. If the integer is odd, add one and divide it by 2. The function does not return anything. In the main function, write a program that asks for an integer input and call the modify function by passing in the reference of that variable as a parameter. An initial code is provided for you. Just fill in the blanks. Input 1. One line containing an integer input Output Enter a number: 5 Before: 5 After: 3
- C++ Write the function with function header double searchId( int idl[], double scorel[], int id, int size) that recieves as arguments the arrays idl (array containing student's IDs) and scorel (array containing their test scores), a student's ID, and the size of the arrays. The arrays are such that the score of the student with ID idl[j] is score [j]. This function searches the array idl for the ID recived, and if it is found, it returns the corresponding test score; otherwise it returns -1. write the function main that does the following: 1.Define the arrays idlist to hold the IDs of 20 students (integer values), and scorelist to hold their test scores (double precision values) 2.Read the 20 student's IDs and their test scores from the standard input into the arrays idlist and scorelist respectively. Each input line will have an ID and a corresponding score. 3.Read the ID of a student and look for their test score (by calling function searchId(). 4.If the ID is found in the list (the…1- Write a user-defined function that accepts an array of integers. The function should generate the percentage each value in the array is of the total of all array values. Store the % value in another array. That array should also be declared as a formal parameter of the function. 2- In the main function, create a prompt that asks the user for inputs to the array. Ask the user to enter up to 20 values, and type -1 when done. (-1 is the sentinel value). It marks the end of the array. A user can put in any number of variables up to 20 (20 is the size of the array, it could be partially filled). 3- Display a table like the following example, showing each data value and what percentage each value is of the total of all array values. Do this by invoking the function in part 1.use C++ programming 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 inches The least rain fell in January with 0.24 inches. The most rain…
- C++ Write a definition of a function called MAX which receives an integer array and its size parameters. It will return the max value of the parameter array.9.12: Element Shifter C++Write a function that accepts an int array and the array’s size as arguments. The function should create a new array that is one element larger than the argument array. The first element of the new array should be set to 0. Element 0 of the argument array should be copied to element 1 of the new array, element 1 of the argument array should be copied to element 2 of the new array, and so forth. The function should return a pointer to the new array. Demonstrate the function by using it in a main program that reads an integer N (that is not more than 50) from standard input and then reads N integers from a file named data into an array. The program then passes the array to your element shifter function, and prints the values of the new expanded and shifted array on standard output, one value per line. You may assume that the file data has at least N values. Prompts And Output Labels. There are no prompts for the integer and no labels for the reversed array…IN C NOT C++ please Write a header file that a) defines a struct called car, which has a double for the weight of the car and a double for its gas mileage (miles per gallon) and b) declares a prototype for a function called get_avg_mpg, which takes a pointer to a car and an int for the length of an array, and returns a double. defines the function get_avg_mpg that was declared in the header file. The function should use pointer arithmetic to iterate through the array of cars and calculate and return the average (mean) mpg. Don't print anything in this function. has a main() that creates an array of three cars on the heap using malloc() and uses pointer arithmetic to iterate through the array and set values for the weight and mpg of each car, then calls get_avg_mpg and prints the result using printf (use the formatting code %.2f). You do not need to take user input; the values for the cars can be hard-coded. #include #include #include "guide.h"
