Both code blocks automate the entry of customer details. The difference, you ask? The advanced code block captures any incorrect input and allows only the correct type of entry. For example, only alphabets are allowed in the "customer name" field.

How did the simple code become advanced? Every day, I revisited the code, asking myself how I could make it better, leading to this improved version.

As my mentor, @Professor Stanley Omeike, often says, "All you need is a one-hour code study."
