  B. Create global variables in the class.

  C. Assign a value directly to the data member.

  D. Provide a private function that assigns a value to the data member.

  Correct Answer: A

  In this example (see below), the Employee class contains two private data members, name and salary. As private members, they cannot be accessed except by member methods. Public methods named GetName and Salary are added to

  allow controlled access to the private members. The name member is accessed by way of a public method, and the salary member is accessed by way of a public read-only property.

  Note: The private keyword is a member access modifier. Private access is the least permissive access level. Private members are accessible only within the body of the class or the struct in which they are declared

  Example:

  class Employee2

  {

  private string name = "FirstName, LastName";

  private double salary = 100.0;

  public string GetName()

  {

  return name;

  }

  public double Salary

  {

  get { return salary; }

  }

  }
