Question
You are expected to use python Object-Oriented
- The standard calculator can perform two types of operations: an addition and a subtraction
- The standard calculator is capable of inputting only two integers. But the scientific calculators can also interpret decimal values.
- The scientific calculator is capable of four operations: addition, subtraction, cosine and sine of values.
- The scientific calculator can accept multiple values for the addition operation.
-
- After performing an addition, the scientific calculator 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)
- After performing an addition, the scientific calculator will send the final result to a
- Create 100 objects for your scientific calculator to enable each object to perform two additions at a time. The values passed to the addition operation are upon your choice.
- Show one example and explain how you can perform a unit testing on the codes you have written.

- Break down the stages involved in the planning phase of web development.arrow_forwardThe concept of public and private class members is part of an approach called object oriented programming. This approach is relevant to many different programming languages and each implements and supports it in slightly different ways. Which of the following sentences are correct about public and private as implemented in python? Python does not support the concepts of public and private members of a class. Python does not directly enforce public and private member access and so will not generate an error if you fail to respect the convention. 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. Python supports the concept of public and private through convention - by adding an underscore '_' at the beginning of the member function or variable.arrow_forwardWrite a python program that Models an Extended Engineering Calculator for solving complex equations, formulas and problems in field of Electrical, Mechanical, Chemical, Electronics, Civil, Metallurgy, Plastics, Ceramics, Physics, Maths and many more.

- By implementing the concepts of Classes and Objects, write a C++ program that determines the slope of a line from the coordinates, P(x,y), of the 2 points. The coordinates of the 2 points: P1 (x1, y1) and P2 (x2, y2) are to he entered from the keyboard. The slope, m, of the line is computed as: m=(y2-y1/x2-x1) Accomplish the following for the given class diagram: 1.) Create the class implementation using C++ 2.) Using the constructor, create 2 objects, P1 and P2, from class Point and store them in the heap memory. 3.) Implement the functions of the 2 objects. NOTE: The member function setXY is used to enter the values of x and y from the keyboard. Sample input/output display: Enter the coordinates of the 1st point (x1 y1): 1 1 Enter the coordinates of the 2nd point (x2 y2): 5 4 The slope of the line, m=0.75arrow_forwardWrite a Python program that works as a text manipulation tool. The paragraph of text that it will manipulate is: "Python is a high-level, general-purpose programming language. It was created by Guido van Rossum and first released in 1991. Python's design philosophy emphasizes code readability with its notable use of significant indentation. Its language constructs and object-oriented approach aim to help programmers write clear, logical code for small and large-scale projects." Perform the following tasks on this paragraph: Split the paragraph into a list of sentences. Hint: You can use the '. ' as the delimiter but when you do that, it will delete the periods. You must go back in and use a for loop to add a period back to the end of each sentence except for the last one. Print the list. Print only the first and last sentence from the list. Convert the first and last sentences to all uppercase and then print them. Join the sentences from step c back into a paragraph.

- Writing a Modular Program in Java Summary In this lab, you add the input and output statements to a partially completed Java program. When completed, the user should be able to enter a year, a month, and a day to determine if the date is valid. Valid years are those that are greater than 0, valid months include the values 1 through 12, and valid days include the values 1 through 31. Instructions Notice that variables have been declared for you. Write the simulated housekeeping() method that contains input statements to retrieve a year, a month, and a day from the user. Add statements to the simulated housekeeping()method that convert the String representation of the year, month, and day to ints. Include the output statements in the simulated endOfJob()method. The format of the output is as follows:month/day/year is a valid date. or month/day/year is an invalid date. Execute the program entering the following date: month = 5, day = 32, year =2014Observe the output of this…arrow_forwardIn the class diagram below we have a parking charge class for an object-oriented parking system that is to be designed using java.

Usually, the architect of the building draws up maps and schematics of a building specifying the building’s characteristics such as how tall it is, how many stories it has etc. Then the actual building itself is built based on the schematics (also known as blueprints). Now it is safe to assume that the actual building is based off the blueprint but is not the blueprint itself and vice versa. The idea of a classes and objects follows a similar ideology. The class file can be considered the blueprint and the object is the building following the analogy mentioned above. The class file contains the details of the object i.e., the object’s attributes (variables) and behavior (methods). Please keep in mind that a class is a template of an eventual object. Although the class has variables, these variables lack an assigned value since each object will have a unique value for that variable. Think of a form that you…arrow_forward
- A manager of a department at Google wants to schedule 15-min coffee chat between two employees every week for his 6 employees. Design and write a program to help this manager. Each employee should have a meeting with a new person. So, no meeting with the same person until they meet all the other colleagues. Use functional programming or object-oriented programing. You can have your own design to cover the requirements but you should consider a design with better time complexity. You can use any data structures (lists, dictionaries, stacks, queues, ...) The number 6 here is an example and imaging there are "n" (an even number) employees in the group (for this example n =6) Every week each employee should have a meeting and just one meeting with one person. Every week they should have a meeting with a new person. Until week 5 ( n-1 weeks) they should have a meeting with the same person. employees = [ employee_1, employee_2, employee_3, employee_4, employee_5, employee_6] It means…arrow_forwardConsider the following skeletal C program: void fun1(void); /* prototype */void fun2(void); /* prototype */void fun3(void); /* prototype */void main() { int a, b, c; . . .}void fun1(void) { int b, c, d; . . .}void fun2(void) { int c, d, e; . . .}void fun3(void) { int d, e, f; . . .}Given the following calling sequences and assuming that dynamic scoping is used, whatvariables are visible during the execution of the last function?
