1. Application variables (visible at the website application level) can be defined in ASP.NET web forms (a server-side technology). Consider that you declare an application variable number_of_hits. Each time a user visits the website this variable is incremented. Therefore, the programmer wrote the following code:

Application("number_of_hits") = Application("number_of_hits") + 1;

1. What issues do you see with this code?
2. Explain your answer, give an example of execution, and correct (if needed) the code.
3. Consider that the programmer uses Session variables:

Session("Name") = "some_name";

What is the difference between Application and Session variables? Do you need to correct this code?
