- INTRODUCTION: In this assignment, you will demonstrate using a database with a menu based program HOW TO SUBMIT YOUR ASSIGNMENT At the top of each of your C++ programs, you should have at least four lines of documentation: Program name (the C++ file name(s)), Author (your name), Date last updated, and Purpose (a brief description of what the program accomplishes). Here is an example: /* Program name: jbtictactoe.cpp* Author: John Doe* Date last updated: 5/1/2017* Purpose: Play the game of Tic-Tac-Toe*/ ASSIGNMENT: SaleCo Write a program that continues a menu based program for the SaleCo database. You have been given a starter file SaleCo.cpp download. This file contains code for running a query to view an invoice. Add to the starter file the code to connect to SaleCo.db download, and to view the information for a customer. You should fill in the viewCustomer function. This function should run a query that gets the customer ID and first and last names for all customers in the database…Analyze the problems carefully. Create the programs of the following. 1.

- Non-homogeneous data items are not allowed to be stored in which of the following data structures?3.Explain the data types: EDT, DDT, IO Derived Variables. Please answer for above question(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.
