a. Python does not directly enforce public and private member access and so will not generate an error if you fail to respect the convention. O b. Python supports the concept of public and private through convention - by adding an underscore '_' at the beginning of the member function or variable. C. Just like other languages that support Object Oriented Programming, such as C++ and Java, Python strictly enforces the concept of public and private class members and will generate an error when it runs if you try to access a private member from outside of the class. O d. Python does not support the concepts of public and private members of a class.
Create a C++ program that simulates a simple inventory management system for a store. The program should allow users to add new products, update product quantities, and generate reports. Follow these guidelines: 1. Implement a class called Product with attributes such as product ID, name, price, and available quantity. 2. Create a class called Inventory that manages an array of products. Include functions to: • Add new products to the inventory. Update the quantity of existing products. • Display details of all products in the inventory. Generate a report showing low-stock products (quantity less than a specified threshold). 3. Start by prompting the user to enter the initial number of products in the inventory. 4. Display a menu that allows users to choose from the following options: Add a new product. · Update product quantity. Display all products in the inventory. • Generate a low-stock report. • Exit the program. ● 5. For each operation, prompt the user for the necessary…
OOP (C++) , give code and compile it.
Write a C++ program that: Implements a class with three data members {sum (int), count (int), avg (float)}. Implement the following 3 member functions: The first function is a default constructor which initializes sum and count to zero. The second function is named add which receives an integer number as input parameter and add it to sum and increment count by 1. • The third function is named output which divides the sum over count and save it to avg then print the avg value). Then, write a program to read numbers from the user until entering zero. The program uses the previous class to calculate and print average of {positive, negative} numbers
Define a class called token number that incorporates a token’s number (which is equal to 744) and its location. Number each token object as it is created. Use two variables of the angle class to represent the token’s latitude and longitude. A member function of the token class should get a position from the user and store it in the object; another should report the serial number and position. Design a main() C++ program that creates three token, asks the user to input the position of each, and then displays each token’s number and position
Consider an example of declaring the examination result.Design three classes: Students, Exam and Result.The student class has data members such as those representing registration number,name etc. Create a class Exam by inheriting the student class. The exam afds data members representing the marks scored in six subjects. Derive class results from the exam class and its own data members such as total marks. Write an interactive program in C++ to model this relationship
Write a program in C++ , which has three classes one, is StudentRecord having members (degree,year) and functions (getdata), the 2nd class is called EmployeeRecordwhich has data members (emp_id and salary). The 3rd class is Manager having title, dues and an object of EmployeeRecord as well asStudentRecord. Create a function of getdata in all of these classes and call where necessary. Using this scenario, show how the concept of Composition works.
3- Write a program to implement a class "student" with the following members. Name of the student. Marks of the student obtained in three subjects. Function to assign initial values. Function to compute total average. Function to display the student's name and the total marks. Write an appropriate main() function to demonstrate the functioning of the above.
(A)Given a parent class "Standard Calculator" consisting of one child class "Scientific Calculator". Create the required parent class and child class using the python class object oriented to create this relationship. 1.The standard calculator(parent) can perform two types of operations: an addition and a subtraction 2.The standard calculator(parent) is capable of inputting only two integers. But the scientific calculators(child) can also interpret decimal values. 3.The scientific calculator(child) is capable of four operations: addition, subtraction, cosine and sine of values. 4.The scientific calculator(child) can accept multiple values for the addition operation. 5.After performing an addition, the scientific calculator(child) will send the final result to a database. (You are not expected to write the codes for the database connection and the queries. You are expected to only show how you can use your scientific calculator object to pass messages to a database object) 6.Create 100…
