Hey there!! :) I want to develop a Program for a Android Phone App for a school project. The Project is a Buy and Sell Books for a University. The goal is that student can look for books to buy and also be able to post a book to sell. Can you help me with a code (preferably made in C, C++, Python or Javascript).

App must have a welcome screen saying, "Welcome, please select an option: 1. Buy Book 2. Sell Book 3. Close App"

In the "Buy Book" category, the user can search for book. In the "Sell Book" catergory, the user can be able to post information about a book to be sold. Information should be as follows: Name of the book Picture of the Book Authour of book Year it was Published Date it was bought Subject Amount the person wants to sell the book for Email Address and Phone Number of Seller (Message must say: "If you are interested in buying you can contact me at:.............................................................." )

Thank You.
