- (Data processing) Write a C++ program that reads the file created in Exercise 4, permits the user to change the hourly wage or years for any employee, and creates a new updated file.arrow_forwardFill-in-the-Blank A pointer that contains the address 0 is called a(n) __________ pointer.arrow_forwardProgram language: C++ A publishing company markets both hardcopy and eBook versions of its work. Create a class publication that stores the title and price of a publication. From this class derive two classes: book, which adds a page count, and digital, which adds a storage capacity in MG bytes. Each of these classes should have a getdata() function to get its data from the user at the keyboard and put a putdata() function to display its data. Add a base class sales that hold an array of three floats so that it can record the dollar sales of a particular publication for the last three months. Include a getData() function to get three sales amounts from the user and a putdata() function to display the sales figures. Modify the book and digital classes so they are derived from both publication and sales. An object of the class book or digital should input and output sales data along with its other data. Write the main function to create a book object and a digital object and test their…arrow_forward

Where various types of medicines are sold! In this pharmacy, there will be 3 parts! Part-1: Admin In the admin part, the admin can add, delete medicines serially wherever he wants! (Medicine Name, Price)! All the added medicines will be stored in ‘Medicine.txt File’ there will be an admin id password! If the input password is wrong it will throw an exception! Part-2: Customer In the Customer Part, There will be 3 portions 1st one is for Sign Up, 2nd one is for Login and the last one is continuing as a guest! In Sign up part, the Customer needs to sign up for Shop Membership. After successful signup customers' data(name, age etc.) will be stored in a different file named ‘Customer Info.txt’! Then log in, in this portion customer needs to log in to his account to buy medicine! The customer will input the serial number and the quantity of the medicine which…arrow_forwardMemory Allocation: Select all of the following statements that are true. The basic idea of contiguous allocation is that each process is contained in a single contiguous section of memory. When using a single-partition allocation scheme, the main memory is usually divided into three partitions. Memory partitioning schemes allow for multiprogramming. When applying the multiple-partition allocation scheme "Fixed Partitions", all partitions always have the same size. When applying the multiple-partition allocation scheme "Variable Partitions", the FirstFit allocation strategy performs best in practice. The Buddy system is prone to internal fragmentation.arrow_forward

- C++ C++ C++arrow_forwardFill-in-the-Blank You should only use the delete operator to deallocate memory that was dynamically acquired with the __________ operator.arrow_forwardInstructions: You are strictly not allowed to use anything other than pointers and dynamic memory. One function should perform one functionality only. Task 1 Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task. Row wise Sum Column wise Sum Diagonal wise Sum Example data.txt 4 5 1.6 10.2 33.7 99 20.5 3 44 50 96.1 2 8 9 4 74 50 99 19.1 Output: Sum row wise: 165, 191, 17, 242.1 Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5 Sum diagonal wise: Not Possible Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.arrow_forward
