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:
Step by step

- Consider the following PHP code:<?phpclass Person{// attribute declarationpublic $name;private $age;// constructor declarationpublic function __construct($n, $a){$this->name = $n;$this->age = $a;}// method declarationprivate function setName($n){$this->name = $n;}public function setAge($a){$this->age = $a;}}?>For each of the following statements, identify whether it will execute or not. Explainwith the reason.1. $p = new Person(null, null);2. $p -> setName('John');3. $p > setAge(30);4. $p -> setName(1);A. Which statement about object-oriented programming in JavaScript is correct? a. JavaScript programs may contain just two kinds of objects: native and host. b. Object-oriented programming refers to the creation of reusable, anonymous functions. c. The code and data within an object cannot be read or modified directly by other programs. d. The encapsulation provided by objects increases complexity but also increases speed. B. Suppose you have written JavaScript constructors for two object classes calledClassAandClassBand then the statementClassA.prototype = new ClassB();.ClassBcan use the value returned by one ofClassA’s methods in one of its own methods becauseClassBinherits all the properties and methods ofClassAin this situation.

- s a simple program where we could identify the fields on the web page easilyusing just the class attribute. There are others that are more complex, and the fieldcan be identified by alternative attributes. Some of these attributes are the id, the tagname, etc. These have not been covered here, but you are likely to need them whenyou deal with more complex web pages—google is probably one of the simplest bydesign, since it is a universal search application where most of its complexity resideson the server end.Write The code for this algorithm?1) The following delegate: delegate string Foo(int bar1, int bar2) Which of the following is equivalent to the Foo delegate? a) Func<string, int, int> b) Func<int, int, string> c) Action<int, int, string> d) Action<string, int, int> 2) Which of the following statements are syntactically correct?
