Go Learning Notes - Part 4: Input Validation, Function & Encapsulating Logic

Today I learned how to encapsulate logic into separate functions to make my Go program cleaner and more organized. I created dedicated functions for greeting users, collecting input, validating data, booking tickets, and extracting first names. I also learned how to return multiple boolean values from a function to validate user input properly. Structuring my code this way made main() easier to read and improved the overall flow of the program. This lesson helped me understand the importance of modular and maintainable code in real-world development.
