Constructors with Parameters

• It's possible to create a class with more than one constructor.

  Employee Fred; /* default construction */
  Employee Harry("Harry Hacker", 40000); /* alternate construction */
  

• All constructors have the same name as the class, but have different parameter lists.

  class Employee
  {
  public:
     Employee()
     Employee(string employee_name, double initial_salary);
     
     void set_salary(double new_salary);
   
     string get_name() const;
     double get_salary() const;
  private:
     string name;
     double salary;
  };
  

• Whenever two functions have the same name but are distinguished by their parameter types, the function name is overloaded.
• The second constructor sets the data fields of the new object based on the parameters.

  Employee::Employee(string employee_name, double initial_salary)
  {
     name = employee_name;
     salary = initial_salary;
  }
