Problem: Assume that you have been hired to write a java application for SQU students' clinic to help receptionist to manage the clinic appointments. There are two type of appointments: emergency appointment and routine appointment. Each appointment has the following information: patient ID, patient name, appointment date and time, and doctor name. Emergency appointment can be scheduled on the same date and the patient symptoms (e.g. cough, fever, cold, diarrhea, injury, ...) should be recorded. While for a routine appointment the patient can decide when he/she would like to have the appointment and the required tests (e.g., blood, x-ray, urine, ...) should also be recorded. Your application should read the initial appointments records from a file called "Clinic Appointments.txt" (check Figure 1 for a sample input file). Your program should then display a menu for the receptionist (shown in the sample runs) then he/she can choose the service. For scheduling an appointment, they can…

Instructions • Input: Prompt the user to enter an arithmetic expression involving two whole numbers and one of the operators , +, -, in the format x operator (e.g., 3 * 2). Use cin >> x >> op >> y; for input. Processing: Use a switch statement to perform the appropriate arithmetic operation based on the entered operator (*, +, -, 7). • Output: Display the result of the arithmetic operation to the user. What to do: 1. Prompt the user to enter an arithmetic expression as x operator y. Use cin >> x >> op >> y; to capture these inputs. 2. Employ a switch statement to determine the appropriate arithmetic operation to perform based on the entered operator. 3. Display the calculated result to the user. Criteria: • Use cin >> x >> op >> y; to capture user input. • Your code must utilize a switch statement for decision-making. • Only the operators *, +, -, / should be accepted. • You must use appropriate variable types and maintain a clear code structure. Code should be well-documented. C:…
Question 17 Choose the right answer properly
Program Purpose - Professional Athletes often hire other professionals to help take care of matters for them. We will group them in four categories: Lawyers, Personal Assistants, Agents, and Trainers. They all get paid a percentage of the athlete's total yearly salary. Lawyers - 10%, Personal Assistants - 3%, Agents - 7%, and Trainers - 5% . Prompt the user to enter the athlete's salary for the year (ensure that the entered value is positive). The user should then enter the name and category of each of the hired professionals. The athlete should be able to hire as many professionals in each category as he/she wants, even if it is more than he/she can afford. Based on the category, calculate the amount that each professional should be paid. After all data has been entered, print the names of each professional hired, how much each is being paid, the total amount the athlete paid, and how much the athlete has left.
