Which primitive data type stores very large whole numbers?

Which primitive data type stores very large whole numbers?

• A. Byte
• B. Short
• C. Long
• D. Int

Answer: (C)

This question is about how much range primitive integer types can represent, i.e., how large a whole number they can store. Among these options, the largest range comes from the type that uses 64 bits. With 64 bits, values span from negative to positive very wide, roughly ±9.22 quintillion in languages like Java. Because it can hold much larger values than the others, it’s the best choice when you truly need very large whole numbers. The smaller types are limited by fewer bits: a byte is 8 bits (tiny range), a short is 16 bits (still modest), and an int is 32 bits (much larger, but not as large as long). So they can’t reliably store very large integers the way long can. If you ever need numbers bigger than what long can hold, you'd turn to arbitrary-precision types or libraries rather than fixed-size primitives.
