Given an application program where it shares a variable X for its tasks' execution, one of the program tasks calls Add method to add value to the variable X. Before the new value of X is saved, another task of the program calls Subtract method to subtract value from the shared variable X. This can cause race condition and arrive incorrect value of the shared variable X. Discover and explain what can be added to this application program in order to prevent race condition from occurring.

Why must a library interface file's inclusion guard symbol or name be distinct? To demonstrate what happens when two libraries #included in the same program share the same symbol, utilize the proof by contradiction technique.
We wish to implement a system that allows the management of Employees and Students. As a first step. you need to implement the above UML diagrams Notes: . ZOOM . PERSON, EMPLOYEE and STUDENT should be public static constants The no-arg constructor will initialize ID, firstName and lastName to their respective null values. It will set personType to PERSON, and sortorder to LAST_NAME The overloaded constructor will assign each parameter to its respective field. sortorder will also be set to LAST_NAME toString() will output type, ID, firstName and lastName, all tab separated. This is an override method equals() will compare if the current object and the parameter contain the same values. This is an override method compareTo() compares the current object and the parameter. This is an override method. It will be used to sort objects Needs the Comparable interface O Will only compare fields depending on the sortorder. For example, if the sortorder is TYPE, it should then compare the…
In C Programming: Write a function printCourseRow() which receives a course pointer and prints all its fields as a single row. Use proper formatting so that when we print 2 or more courses as rows, the same members align below each other. Test the function, but don’t include the testing code in your homework.Upload a screenshot of a sample output.

I want code in MATLAB In this part, you are required to implement Quiz Application. Add 10 questions in your program of any domain with their answers. You many use strcmpi function to compare user answer with the saved answer. If the answer is correct/matched with the saved answer user score 1 point. Functionalities that need to be implemented in Quiz application are: - 1. The user will be asked to enter the name and then asked questions one by one. 2. The user should be given the choice to pass any question. If a user passes any question, no marks will be added or deducted. 3. The user should be able to see his/her total score after every question. 4. If 70% of the answers by the user are correct, then the user passes the Quiz otherwise, the user fails the Quiz. In both cases, the user will be displayed with a message, for example, “Congratulations, you got 8/10 correct, You Pass the Exam” or “Unfortunately, you got only 4/10, You failed the Exam”. 5. At the end of the Quiz, a user…
Use reflection function to write a Data Marshaler go language.
Follow the instructions from your instructor to accomplish the following in-class lab assignment. The Problem to Solve: The user needs a program to interact with employee records. The kinds of interactions are "Add an Employee" (Create record), "Show All Employees" (Read records), "View an Employee" (Read one record), "Update an Employee" (Update or change a record), and "Delete an Employee" (Delete a record). These interactions form the standard data processes in much of business software Create, Read, Update, and Delete, which are known by the acronym CRUD. The user needs to continue working with records until they are ready to tell the program. To do this, the program will present a menu of CRUD options and an option to Quit. The user will choose an option and the program will react accordingly. For this lab, the program will only print out which option the user chose. In later labs, we will add more functionality. Questions: What are the inputs needed to solve this…
FOR JAVA Write an API, an implementation and a typical client code for a Multiple Counter abstract data type which can act like multiple independent counters. Your implementation should not use or contain multiple instances of another Counter type, you should host the necessary data representation directly in your implementation. The constructor must take a parameter which indicates how many counters will be hosted in the object. There should be an instance method which increments the value of the counter specified by the integer index passed as argument. There should be an instance method which decrements the value of the counter specified by the integer index passed as argument, but it should not let the counter to take a negative value, a counter with value 0 should stay the same (without any error) if decrement is called. There should be an instance method which returns the value of a counter specified by the integer index passed as argument. On your client code; ▪…
