Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming 4. a. Create a program named WritePatientRecords that allows a doctor’s staff to enter  data about patients and saves the data to a file. Create a Patient class that contains  fields for ID number, name, and current balance owed to the doctor’s office.   b. Create a program named ReadPatientRecords that reads the file created in  Exercise 4a and displays each patient’s data on the screen.  c. Create a program named FindPatientRecords that prompts the user for an ID  number, reads the file created in Exercise 4a, and displays data for the specified record.   d. Create a program named FindPatientRecords2 that prompts the user for a  minimum balance due, reads the file created in Exercise 4a, and displays Using  console application, combine all four parts in one program and name it PatientRecords, please make sure to include exception handling in this program.

Assignment 1 University Library SystemIn this assignment you are going to implement your own version of university library system,The system will have two different sides , the first one is to help the librarian to do his job and the other side for admin to manage every one permissions in the system , so You should provide the following features in your system: Admin viewo Add/remove Studentso Add/remove librariano Add/remove other admins  Librarian viewo Add/Delete bookso Issue/Return bookso View bookso View Issued bookso Log in /log outo Search for the book(id/name) Simple backend for your system , You could use a file each row should represent item o Books File should be something like:Id , Book Name, Author Name, Available quantity, Issued Quantity 1,Oliver Twist, Charles Dickens,98,2In the previous the first row was the name of each column , you can do that orhandle it in your code , id =1 , Book Name =Oliver Twist ..Etc.  Tables neededo Books Id Book Name Author Name…

C++ Assignment Setup  Part 1: Working With Process IDs  Modify the getProcessID() function in the file named Processes.cpp The function must find and store the process's own process id The function must return the process id to the calling program. Note that the function currently returns a default value of -1.Hint: search for “process id” in the “System Calls” section of the Linux manual. Part 2: Working With Multiple Processes  Modify the createNewProcess() function in the file named Processes.cpp as follows: The child process must print the message I am a child process! The child process must then return a string with the message I am bored of my parent, switching programs now The parent process must print the message I just became a parent! The parent process must then wait until the child process terminates, at which point it must return a string with the message My child process just terminated! and then terminate itself. Hint: search for “wait for process” in…

IN C++ VISUAL STUDIO   Create two classes one to read data from file, and the other to write data into a file. The data can be about employees having information about employee name, id and designation. You must create a class for employee. There is  a total of 3 classes in your program. In the second class, which is about file writing, you have to write data about 10 employees in file. You can get data from user. In reading class, you have to read information about a specific employee whose id is given by user. Finally write a function to show data about employees whose designation is  “manager”.

Task 2: Printing the time that the file path was created (50 points) The stat system call can access a file by name and retrieve file status information. It is given by: int stat (const char *pathname, struct stat *buf); This system call retums a stat structure (both the function and struct are called stat), which contains the following fields: struct stat { dev_t st_dev; /* ID of device containing file */ ino_t st_ino; /* inode number */ mode_t st_mode; /* protection */ nlink t st nlink; /* number of hard links */ uid t st uid; /* user ID of owner */ gid_t st gid; /* group ID of owner */ dev_t st_rdev; /* device ID (if special file) */ off t st size; * total size, in bytes */ blksize_t st_blksize; blocksize for file system IO */ blkent t st blocks; /* number of 512B blocks allocated */ time_t st_atime; /* time of last access */ time_t st_mtime; * time of last modification */ time_t st_ctime; /* time of last status change */ On success, zero is returned. On error, -1 is returned, and…

C++ Visual Studio 2019 Instructions Complete #1 & #2.  Please submit just one file for the classes and main to test the classes. Just create the classes before main and submit only one cpp file. Do not create separate header files. Please note: the deleteNode needs to initialize the *nodePtr and the *previousNode. The code to do this can be copied from here: ListNode *nodePtr, *previousNode = nullptr;

Write the code in python  Create an application that can create, display, search and maintain the book information for a bookstore.  Requirements:  1) you need to use functions to write code for each menu item.  2) Information of books will be saved in a file, e.g,, books.txt.  3)User can add any number of books to the booklist. There can be 5 books or 500 books. In order for your program to handle it without any changes in the code, you cannot hardcode the number of books in your program.
