Answer 1

abstract class Person {
    abstract pName: string;

    display(): void{
        console.log(this.pName);
    }
}

class Employee extends Person { 
    pName: string;
    eID: number;
    
    constructor(name: string, ID: number) { 
        super();
        
        this.eID = ID;
        this.pName = name;

let emp: Person = new Employee('Professor Albus Dumbledore', 83736);
emp.display(); 



  
  
      
/*
