- (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.(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=FIn 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.
- 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…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"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 =…
- 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 twice the size of the argument array. The function should copy the contents of the argument array to the new array and initialize the unused elements of the second array with 0. The function should return a pointer to the new array. Demonstrate the function in a complete program.38. To pass a scalar variable by reference in C++, you need to include the ____ operator before the formal parameter’s name in the receiving function’s header. a. & c. $ b. * d. @ 42. A simple, or ____ variable, is one that is unrelated to any other variable in memory. a. scalar b. vector c. independent d. dependent 43. You may use an assignment statement or the ____ operator to enter data into an array element. a. comparison b. arithmetic c. extraction d. insertion 44. Each of the ____ (variables) in an array has the same data type. a.elements b.objects c.structures d.subscriptsIn C++ Create a function called CopyAndInsertArray. It should take in two arrays (the first array should be of size n and the second array should be of size n+1). The function should also take in a position and a number. It should copy the first array into the second array and place the new number at the proper position. In other words, you are creating a function that inserts a value into an array.
- Part 1 //Program Statment: Write a program(in c++) that first reads an integer for the array // size , then reads numbers into the array, and displays distinct numbers (i.e.// if a number appears multiple times, it is displayed only once). (Hint: Read // a number and store it to an array if it is new. If the number is already in // the array, discard it. After the input, the array contains the distinct numbers.) Part 2 //Program statment: When array is created, its size is fixed. Occasionally, you//need to add more values to an array, but the array is full. In this case , you //may create a new larger array to replace the existing array. Write a function //with the header;// // int * doubleCapacity(const int *list, int size)// //The function returns a new array that doubles the size of the parameter list.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.I need help writing a C++ code. I need help writing a that dynamically allocates an array enough to hold a user-defined number of test scores. Once all the scores are entered the array needs to be passed to a function that sorts them in ascending order. Another function should be called that calculates the average scores. Finally, the program should display the sorted list of scores sorted from ascending to descending and averages them with proper headings. Please use a use pointer rather than an array notationion. also please don't allow negative scores.
