Question

T/F : If a non-letter argument is passed to the toLowerCase or toUpperCase method, the boolean value false is returned

Answer 1

False.

Step-by-step explanation:

If a non-letter argument is passed to the toLowerCase() or toUpperCase() method in most programming languages, it typically does not return a boolean value. Instead, it usually returns the same non-letter argument without any modification.

These methods are typically used to convert the case of letters in a string. If a letter is passed as an argument, it will be converted to either lowercase or uppercase, respectively. However, if a non-letter character (such as a number, symbol, or whitespace) is passed, it will not be affected, and the original value will be returned unchanged.
