Lab Tasks

Task 1: Complete your blog!

In the previous lab, we've created a simple blog, you should complete this blog, you should add a class named Category, this class will hold the posts of this category, you could only list posts in a certain category, assume that each category stores its posts in a different folder.

You will have a static list of categories:

Enter Selection: 1
  Enter Item Code: 100
  Enter Item Qty : 2
  Enter Item Code: 101
