Hi there. I'm new to programming in general but have made some simple to moderate programs before. What I'm currently struggling to figure out is how I would create a program that would allow me to search for a specific book defined by the author, year of publication, paper title or name of journal or conference within a text file of books and output the book, output an error message saying the book doesn't exits or output an error message if the user doesn't input all the information. I'm not simply asking for someone to write the entire code for me, but rather give me an indication as to how I could start with this, explain what functions I would need to use, or to point me to a website where I could find relevant information to help with this.
