A program is to be written to authenticate a username and password entered by the user.

Table 1 shows the only two pairs of valid credentials.

Write a C# program to authenticate a username and password.

The program should:

• Ask the user to input a username
• Ask the user to input a password
• Display the message Access Denied if the username and password pair entered is not valid
• Display the message Access Granted if the username and password pair entered is valid
• Repeat these steps until a valid username and password pair is entered.

You should use meaningful variable names and correct C# syntax in your answer.
