OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- Evaluating Postfix Expression The Postfix notation is used to represent algebraic expressions. The expressions written in postfix form are evaluated faster compared to infix notation as parenthesis are not required in postfix. We have discussed infix to postfix conversion in the class. Write a Java program that will input a valid postfix expression. The expression may accept a whole number or a real number. Every operand and operator should be separated by a space. Make sure to trap possible errors.Sample Output (Must be implement in GUI)Part 2 - OddOrEven ClassWrite a program that prompts the user to enter an integer. The program should display “The input is odd" to the screen if the input is odd and displays “The input is even" to the screen if the input is even. Hint: Consider using the mod (%) operatorPart 2 - OddOrEven ClassIn bluej. Write a program that prompts the user to enter an integer. The program should display “The input is odd" to the screen if the input is odd and displays “The input is even" to the screen if the input is even. Hint: Consider using the mod (%) operator.
- Input operations are supported by class__________________Parking Charges Program in java Write a program that works out the amount a person has to pay for parking in a car park in a tourist town. If they say they are disabled, they are told it is free. Otherwise they enter the number of hours as a whole number (1-8) that they wish to park as well as whether they have an “I live locally” badge or are an old age pensioner both of which leads to a discount. The program tells them the cost to park. The calculation is done in this program as follows. If they are disabled it is free. Otherwise ... Take number of hours they wish to park and give a basic charge: • • • • 1 hour: 3.00 pounds 2-4 hours: 4.00 pounds 5-6 hours: 4.50 pounds 7-8 hours: 5.50 pounds Next modify the resulting charge based on whether they are local or not: • If local: subtract 1 pound If OAP: subtract 2 poundsYour program MUST include methods including ones that - asks for the hours and returns the basic charge. - asks whether they live locally /…Transcribed Image Text 7-a) Danish works as a constructor. Like all constructors, he is also a beer fan. He likes beer so much that has K cups of beer daily. However, having more than K cups doesn't suit him, because the excess beer won't allow him to sleep at night. Danish's working day is divided into N periods. For every period, he knows how many kilobytes of weight he can lift. During each of the periods, Danish can either have or not to have one bottle of beer. If he is having a bottle of beer in some period, the amount of work in this period drops to zero. But he also gets a productivity boost, if he decides to skip beer during a period and the last bottle of beer, he had was no more than D periods ago, the amount of work during such a period is M times the usual.
- Output operations are supported by class_________________T/F In Java a constructor must always return an int.Write program in C++ Language The other solutions on chegg were incorrect! Please read carefully! Write a program that defines and tests a class called COP3014. The class resembles aclassroom. It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some…
- The following is a definition of class Example:class Example{public:Example( int y = 10 ): data( y ){// empty body} // end Example constructorint getIncrementedData() const{return ++data;} // end function getIncrementedDatastatic int getCount(){cout << "Data is " << data << endl;return count;} // end function getCountprivate:int data;static int count;}; // end class Examplec++ (A) write the definition of the Circle class. (B) Write a test program implementing the relational operators (<, <=, ==, ! =, >, >=) to compare the radius of two circle. See the sample outcome Figure 1. in the test program, your code will perform the followings; (A) Creates two circles with the radius 5 and 6 respectively. (B) Use the operator < and display the area of the circle that has the smaller radius. (C) Use the operator == and display the area of the bigger circle if the two circles are not the same. You need to use one of the operators to determine which radius is bigger.Problem Statement: The mathematician Conway imagined a game, called game of life, which considered cells that are susceptible to reproduce, disappear, or survive when they obey certain rules. These cells are represented by elements on a grid of squares, where a grid has an arbitrary size. Thus, each cell (except those on the boundaries of the grid) is surrounded by eight squares that contain other cells. The rules are stated as follows: 1. Survival: Each cell that has two or three adjacent cells survives until the next generation.2. Death: Each cell that has at least four adjacent cells disappears (or dies) by overpopulation. Also, each cell that has at most one adjacent cell dies by isolation.3. Birth: Each empty square (i.e., dead cell) that is adjacent to exactly three cells gives birthto a new cell for the next generation.It is worth noting that all births and deaths occur at the same time during a generation. Write a program that simulates this game and displays all successive…
