- Using C++ create a class Parent with Name & CNIC number as a private data members. Create a getinput & showinput functions & set values through getter & setters. Create another class Student with section as private data member & examscore as a protected data members. Class Student is a relationship with class Parent. Create a getdata & displaydata functions & set values through getter & setters. Create a third class Resultcard with remarksbyteacher as a private data members. Create a function getgrade which calculate the grade of students according to their marks and then display the report card of student. Class Resultcard is a relation with class Student.Computer Science UML is a standard language that allows you to capture different aspects of your system in well-defined graphical models. Some of the models capture static aspects for the system and one will capture dynamic behavior for the system. In this project, you are required to draw an activity diagram showing the actions and events involved in depositing a check to a bank account using a mobile app. In particular, your paper should provide the following: A simple pseudo-code that captures the sequence of that process A detailed activity diagram that maps to your pseudo code you identified Make sure to specify clearly any assumptions you feel important to understand your logic I'm a bit lost on what to do and really just need an example of what this is asking and then suggestions on how to go about doing the assignment.Design a class diagram for the following project description online retailer system The system will deal with a number of domain entities – including items, orders, and customers. The items that we sell fall into user-defined categories. Some categories, such as liquor, are flagged as being restricted – customers under the age of 18 are not allowed to buy restricted items, and the system should raise an exception if they attempt to. In addition, we have to maintain certain details on all items – such as the item name, description, price, and category The system also need to maintain customer information – including names, email addresses, and age. Each customer has to have an address, to be used for billing and delivery. Customers can change their details whenever they want When a customer places an order, the system will calculate a delivery fee by using delivery priority and distance from warehouse. Orders of more than $100 qualify for free delivery, at normal priority. Overnight…

Question half solution is here please write what is main disadvantages of this approach? Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }
