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)ISP- Java Your program must include (but not limited to) the following: • Comments • Javadoc comments for method(s) and class(s) • Input(s) and output(s) • Decision structures • Loops • Arrays • Methods • Classes & Objects Be as creative as possible!oop using c++ please give me full naswer thanks Design a class named Person and its two subclasses named Student and Employee.

A student has a status (String). An employee has an office, salary, and date hired A faculty member has office hours and rank A staff member has a title. Create display method in each class. Also create getter, setter and default constructor in above task.
- Question: Write a program with C# to Simulate a game of tic tac toe. A game of tic tac toe has two players. A Player class is required to store /represent information about each player. The UML diagram is given below. Player -name: string -symbol :char Player (name:string,symbol:char) getName():string getSymbol():char getInfo():string The tic tac toe board will be represented by a two dimensional array of size 3 by 3 characters. At the start of the game each cell is empty (must be set to the underscore character ‘_’). Program flow: Your program must ask for each player’s name and their special symbol or character (usually an ‘X’ or ‘O’). Display each player’s name and symbol. The program must then display the board (the 2 dimensional array). The player whose turn it is has their name displayed and is asked for a row and column number to place their symbol. They can enter -1 -1 as the row and column number to quit. Repeat 2 and 3 until one player enters -1 -1.…1. class rectangle { private: double width; double length; 3. 4. public: rectangle(double w=0.0, double l=0.0) { width=w; 5. б. 7. length=w; } void operator++() //prefix ++ operator 10. {++width; ++length; } 11. void operator++() //postfix ++ operator 12. {width++; length++; } 8. 9. 13. }; Which line of the above C++ code contains an error?

You are required to create a simple command line application that allows users to do two basic things, (1) create an email comprising of properties, to, from, subject and message and (2) to create a book chapter that has the properties of chapter title, chapter number and chapter contents. When the program begins its execution, your program should first ask the user for the sender and receiver for the email, its subject and lastly its message; it should then display the entire email in a well-structured format. Second, the program should ask the user for the book chapter name, its number and finally the contents that go in the chapter. At the end, display the book chapter along with all the properties.
