In a company's database, each customer's first initial is stored in a single field so that it can easily be accessed for personalized email greetings. What data type would be best suited for storing this single character?
Integer
String
Char
Float
The 'Char' data type is used to store a single character, such as a letter, number, or symbol. Given that a single character (the customer's first initial) needs to be stored, 'Char' is the most efficient and suitable data type. Using 'String' could also store a character but is more appropriate for multiple characters, which in this case is unnecessary and would not be as space-efficient. 'Integers' are used for whole numbers and 'Floats' for numbers with decimals, making them incorrect choices for storing a single character.
