Bymadwithcode

Write a C# program that gets a person’s date of birth as input   and calculates his/her age and display the age. The program should also check whether the person is an adult or child. Display the results as given in the sample output.

 Create a class called Person. 

 1.      Populate the Person class with the following private fields. :

·         String   firstName   // stores the first name of the person

·         String  lastName   //stores the last name of the person.

·         DateTime  dob   // stores the date of birth of the person

2.      Add read-write properties for the above three instance fields and store the information

3.      Add read-only propertiy Adult   that return the following computed information:   

public String Adult  // Check the age ,of the person , and if he is  18 or above   return a string “Adult”  and  if he is below 18 return  “Child”.

4.      Include a Method DisplayDetails 

         public void DisplayDetails() // Displays the details of the person.

5.      Include a method with the below signature that returns the age of the person.     

public int GetAge(DateTime dob)

Note:

In Sample input we have assumed the date as 16/07/2021, but you assume the Date as Today’s Date.

Create objects for person  from a class called Program that contains the Main method and display the details from the DisplayDetails method.

Note:

Don’t create new namespaces.

Create classes with pubic access specifier.

Follow the naming conventions strictly.
