Question

What are the sizes of Integer/Long/Pointer in LP64 programming model?

1) 8/8/8
2) 4/4/8
3) 4/8/8
4) Cannot be determined

Answer 1

In the LP64 programming model, the size of an Integer is 4 bytes, the size of a Long is 8 bytes, and the size of a Pointer is 8 bytes.

Step-by-step explanation:

In the LP64 programming model, the sizes of Integer, Long, and Pointer are as follows:

1. 8/8/8: This option is incorrect because in the LP64 model, the size of an Integer is 4 bytes, the size of a Long is 8 bytes, and the size of a Pointer is 8 bytes.
2. 4/4/8: This option is partially correct. The size of an Integer and a Long is indeed 4 bytes, but the size of a Pointer is 8 bytes.
3. 4/8/8: This option is incorrect because the size of an Integer is 4 bytes, not 8 bytes.
4. Cannot be determined: This option is incorrect because the sizes can be determined based on the LP64 programming model.
