Write a class named Employee that has the following member variables: name. A string that holds the employee’s name. idNumber. An int variable that holds the employee’s ID number. department. A string that holds the name of the department where the employee works. position. A string that holds the employee’s job title. The class should have the following constructors: A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position. A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string (""). A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable. Write appropriate mutator functions that store values in these member variables and accessor functions that return the values in these member variables. Once you have written the class, write a separate program that creates three Employee objects to hold the following data.

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:
Write a class named Employee that has the following member variables:
name. A string that holds the employee’s name.
idNumber. An int variable that holds the employee’s ID number.
department. A string that holds the name of the department where the employee works.
position. A string that holds the employee’s job title.
The class should have the following constructors:
A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name, employee’s ID number, department, and position.
A constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee’s name and ID number. The department and position fields should be assigned an empty string ("").
A default constructor that assigns empty strings ("") to the name, department, and position member variables, and 0 to the idNumber member variable.
Write appropriate mutator functions that store values in these member variables and accessor functions that return the values in these member variables. Once you have written the class, write a separate program that creates three Employee objects to hold the following data.

- Class is a user-defined type consisting of a block of code which contains functions and variable which are accessed within that class or class object.
- The constructors are the same name as the class name and these are called when the object is created.
- The constructor is parameterized or default constructor.
- The parameterized constructor takes an argument and doesn't return anything even void also. It can be written as
constructor_name(argument1, argument2,.....argument3)
{
block of code
}
