Case 1: A local pharmacy added a software requirement to its cash register to prevent sales of more than $75 to customers owing more than $200 on their pharmacy credit card. The programmer did not fully understand the specification and created a sales limit of $500 within the program. This defect never caused a failure since no client could purchase more than $500 worth of items given that the pharmacy credit card had a limit of $400.

- Object Oriented Programming in C++ Q. . Pakistan Cricket Board (PCB) is looking for a solution to record the information about their different types of players. Under the contract of PCB there are three (3) different type of players. Suppose you are asked to develop a system, which input all the data of player and calculate & print the total scores and income of a cricket player of Pakistan cricket team. Each player is identified by name, CNIC, income and score. There are three types of players – Test, OneDay, T20. A player can be in all types but If player is not playing in any one or more types then you will input zero(0) for the data members of that class. Each type of Player gets paid using a different formula. OneDay Players are paid by their Monthly fixed salary of Rs.100,000/- per month, test players are paid by the number of hours they played at rate of Rs.2000/- per hour, while T20 players are being played by the number of matches they have played at the rate of 50000/-…Deeper access is better from a programming perspective than shallower access; avoid making a judgment only on the basis of performance.c++ or java or in pseudo code with explaining note: if anything is unclear or seems left out make an assumption and document your assumption Implement an algorithm for assigning seats within a movie theater tofulfill reservation requests.

You can have different types of users of this system, including staff, student and visitor. Each user will have an account affiliated with them. The library system will have Books in it as well, which can be added, removed or lent based on the request from the user. The issuing authority can only be Librarian (separate class). Books can have further various categories, like Computer Books, History Books, Basic Science Books and more. All users when issuing the books, must pay a specific amount of fare per book. Students are given 20% discount on each book while each staff member is given 50% discount. Visitors are to pay complete fare 1. You are required to code this scenario in Java and using Aggregation, Inheritance, Polymorphism, Overriding and Overloading where applicable (carefully) 2. You are required to make a class diagram of the given scenario, with proper data members and methods, using…Design ADT for a cave and a cave system. An archeologist should be able to add a newly discovered cave to a cave system and to connect two caves together by a tunnel. Duplicate caves—based on GPS coordinates—are not permitted. Archeologists should also be able to list the caves in a given cave system. Specify each ADT operation by stating its purpose, describing its parameters, and writing a pseudocode version of its header. Then Java interface for a cave's methods and one for the methods of a cave system. Include javadoc-style comments in your code. Java program
- Programming knowledge is based on the programmer’s experience with various standardstructures, generic designs and templates, to address specific scenarios in real-life scenarios.Therefore, it is crucial to provide practical evidence of the application of concepts presented inthis module.The scenario should be based on the case study given below:DVD store application:For a family or an individual, a favourite place to go on weekends or holidays is to aDVD store to rent movies. A new DVD store in your neighbourhood is about to open.However, it does not have a program to keep track of its DVDs and customers. Thestore managers want someone to write a program for their system so that the DVDstore can function. The program should be able to perform the following operations:1. Rent a DVD; that is, check out a DVD.2. Return, or check in, a DVD.3. Create a list of DVDs owned by the store.4. Show the details of a particular DVD.5. Print a list of all of the DVDs in the store.6. Check whether a…You MUST develop a program using Python language that will satisfy the functionality specified above. Based on your understanding and interpretation, there are many ways to develop such a program to satisfy above requirement specification. Therefore, please use your creativity to come up with a suitable design, that is which class will contain which functionality, which methods and so on. Please also keep your main focus to use various good programming techniques and practices that you have learnt in this course. For example, you should use proper exception handling with appropriate error messages at suitable places where you can expect exceptions and errors in your programme. The final output of your implementation should be a bunch of Python classes with some example code for testing the use cases/ scenarios such as 1. Adding/deleting a new course, 2. Creating and adding students to a course, 3. Grading of the mandatory assignments i.e. a pass/fail for a student etc. 4. To get an…For C++ Programming II D.S. Malik Programming Exercise 10-16: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your…
- Instruction: Based from the given scenarios, create a program (flowchart or actual source code) that applies to what was described. 1. Suppose you know that every employee in your organization has a seven-digit ID number used for logging on to the computer system. A loop would be useful to guess every combination of seven digits in an ID. Are there any circumstances in which you should try to guess another employee’s ID number? 2. Consider the structure of a class roster for a university course. It contains a row for each student enrolled in the course. What might the array used to produce this report look like? Discuss the elements that would be needed in this structure.Every year, the university creates and trains a new team of students toparticipate in programming competitions. In order to automate the process ofcreating this team, the university is planning to create a new system using anobject-oriented approach. To this end, we know the following facts:- In order to create the team of students, a committee is appointed by theuniversity.- The committee includes several members, one of them is the Head of theCommittee (HoC).- A member of the committee could be a faculty member, and admin member,a student, or a manager.- The candidates for the team could apply for several positions (in other words,the team has several positions).- A candidate must be a student.- The team of students must have a leader. The leader is one of the studentswho are members of the team.- Several candidates can apply for a given position. A candidate could beeligible or could be rejected for the position. A candidate can also be selectedfor the position with a given score.…Use java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format.
