Question

What is meaning of ILP32 ?
A. 32 bit Integrated, Long & Pointer
B. 32 bit Integer, Long & Pointer
C. 32 bit Integer, Long & Point
D. 32 bit Integer, Lost & Pointer

Answer 1

Answer:

B. 32 bit Integer, Long & Pointer

Explanation:

B. 32 bit Integer, Long & Pointer

An integer in the range [-2147483648 to 2147483647] is represented as a signed integer, a 32-bit datum. A 32-bit datum known as an unsigned integer encodes a nonnegative integer in the [0 to 4294967295] range. The twos complement notation is used to express signed integers.

Windows: 64-bit integers have unique new data types introduced, although long and int remain 32-bit in length.

However, the majority of common environments (Windows, Linux, and OS X) have pointer sizes of 4 for 32-bit and 8 for 64-bit systems.

On the same system, a long integer can represent a whole integer with a range that is more than or equal to a standard integer. Long is used to represent it in C.

Answer 2

Answer:

32 bit integer, long and pointer

Explanation:

• The full form of ILP32 is Integer, long, pointer of 32 bit data type model.
• Here, the range of the integer lies between -2147483648 to 2147483647.

ILP32 :

• ILP32 is a 32 bit Solaris C language data model.
• It defines the integer, long and pointer in 32 bits.
• It also defines short as 16 bits and char as 8 bits.

In ILP32 :

1. char  = 8 bits
2. short = 16 bits
3. int = 32 bits
4. long = 32 bits
5. long long = 34 bits
6. pointer = 32 bits

ILP32 :

• This data model uses 4/4/4 data type size model.

• It also includes long long type data model.
