Choosing Appropriate Data Types for a User’s Middle Initial

These flashcards review which data type is best for a user’s middle initial and why alternative types (Integer, String, Boolean) are not appropriate.

What is the most appropriate data type for storing a user’s middle initial?

The Character (char) data type, because a middle initial is a single letter.

Why is the Integer data type inappropriate for storing a user’s middle initial?

Integers can only hold numeric values, so they cannot represent alphabetic characters like a middle initial.

Why is the String data type not the best choice for storing a user’s middle initial?

Strings are designed to hold multiple characters; using a String for just one character is inefficient compared to a Character (char).

Why is the Boolean data type not suitable for storing a user’s middle initial?

Boolean data types only store true/false values and cannot store letters or other characters.
