Using flags to control behavior

The flags package provides a higher-level and more structured approach to reading arguments compared to directly using the os package. Flags simplify the process of parsing and handling command-line input, making it easier for developers to create robust and user-friendly command-line applications.

The flags package allows you to define flags with associated types and default values, making it clear what kind of input a user is expected to provide. It also automatically generates help messages, making your program more self-documenting. Here’s a brief overview of how the flags package can help in reading and handling command-line arguments:

• Define flags: You can define flags, along with their types and default values. This provides a clear and structured way to specify expected inputs.
• Parse flags: After defining flags, you can parse the command-line arguments. This initializes flag variables with the values provided by a user.
