Answer:
#include <iostream>
using namespace std;
void divide(int numerator, int denominator, int *quotient, int *remainder)
{
 *quotient = (int)(numerator / denominator);
 *remainder = numerator % denominator;
}
int main()
{
 int num = 42, den = 5, quotient=0, remainder=0;
 divide(num, den, "ient, &remainder);
  
 return 0;
}
Explanation:
The exercise is for "Call by pointers". This technique is particularly useful when a variable needs to be changed by a function. In our case, the quotient and the remainder. The '&' is passing by address. Since the function is calling a pointer. We need to pass an address. This way, the function will alter the value at the address. 
To sum up, in case we hadn't used pointers here, the quotient and remainder that we set to '0' would have remained zero because the function would've made copies of them, altered the copies and then DELETED the copies. When we pass by pointer, the computer goes inside the memory and changes it at the address. No new copies are made. And the value of the variable is updated.

Answer:
//The Employee Class
public class Employee {
    char name;
    long  ID;
//The constructor   
 public Employee(char name, long ID) {
        this.name = name;
        this.ID = ID;
    }
//Method Get Person
    public void getPerson (char newName, long newId){
        this.ID = newName;
        this.ID = newId;
    }
//Method Print
    public void print(){
        System.out.println("The class attributes are: EmpName "+name+" EmpId "+ID);
    }
}
The working of the class is shown below in another class EmployeeTest
Explanation:
public class EmployeeTest {
    public static void main(String[] args) {
        Employee employee1 = new Employee('a', 121);
        Employee employee2 = new Employee('b', 122);
        Employee employee3 = new Employee('c', 123);
        employee1.print();
        employee2.print();
        employee3.print();
    }
}
In the EmployeeTest class, Three objects of the Employee class are created.
The method print() is then called on each instance of the class.
