- please write with proper explanation. 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*/ }2- Design a system which keeps track of the jobs that it is performing an a company. • Each job is of a certain type, which is also identified by a type name. • Each job performed is given a number, a starting date and a promised finishing data. The customer of a job is noted. Any job of a given type is done in one or more steps, each of which is identified by a code and name. The steps are numbered as 1, 2, .... The average time to complete a step is also recorded. • It is possible for a given job step to be used in several types of jobs. When a job is accepted, the required steps to complete the job are scheduled and the estimated start and completion dates are recorded for each step. • What are the entities in this database and what are their attributes? What are the keys? What are the relationships and their attributes? Indicate both the cardinality and participation of each relationship. Draw an extended entity-relationship (EER) diagram for this database.Create a PAYROLL MANAGEMENT SYSTEM IN C++ There will be two Log in cases: log in as: Admin-employer User-employee Functions of Admin Login: 1.Add new record of employee 2.Edit a record 3.Delete a record 4.Search a record 5.View the list of Employee 6.Print the salary slip Functions of User Login: 1.Search a record 2.View the list of Employee 3.Print the salary slip Note: Code should be run in Codeblocks C++.

Student class stores name, roll no, and marks in 5 subjects (use appropriate data types). Use the concepts of constructor and destructors Write a menu-driven C program that creates a Student Log object studobj and performs operations on it. Your program should repeatedly read a character from the user and do the following: R- Read name and rollno into studobj from the user M - Read 5 integers from the user and Set marks C - Check whether the student passes (gets 50% marks).

- PLEASE CODE IN PYTHON Problem DescriptionBoring is a type of drilling, specifically, the drilling of a tunnel, well, or hole in the earth. With some recent events, such as the Deepwater Horizon oil spill and the rescue of Chilean miners, the public became aware of the sophistication of the current boring technology. Using the technique known as geosteering, drill operators can drill wells vertically, horizontally, or even on a slant angle. A well plan is prepared before drilling, which specifies a sequence of lines, representing a geometrical shape of the future well. However, as new information becomes available during drilling, the model can be updated and the well plan modified.Your task is to write a program that verifies validity of a well plan by verifying that the borehole will not intersect itself. A two-dimensional well plan is used to represent a vertical cross-section of the borehole, and this well plan includes some drilling that has occurred starting at (0, −1) and moving…Problem: UMLThis exercise is for a simplified supermarket cash register system.
