What is TRUE about a long integer?

Question

It uses more than 32 bits.

It has a maximum of 17 bits.

It has a decimal.

It uses only 1s and 0s.

Answer 1

To determine what is TRUE about a long integer, let's analyze each statement:

1. It uses more than 32 bits.
   This is typically true for "long" integers in many programming languages. For example, in languages like C and Java, a "long" integer often uses 64 bits (on 64-bit systems).

2. It has a maximum of 17 bits.
   This statement is false. A long integer uses significantly more than 17 bits (usually at least 32 or 64 bits).

3. It has a decimal.
   This statement can be misleading. Integers, including long integers, are whole numbers and do not have decimals. However, they can represent numbers that may conceptually be thought of as "decimal" (i.e., base-10) when viewed as numbers.

4. It uses only 1s and 0s.
   This statement is true in the context of digital representation. All data in computers, including long integers, is ultimately represented in binary form, which consists of 1s and 0s.

Conclusion:

The TRUE statements about a long integer are:

• It uses more than 32 bits. (Depending on the language and architecture)
• It uses only 1s and 0s.

So, both the first and last statements are true.
