Module 4 Quiz Questions Flashcards
The EQU directive permits a constant to be redefined at any point in a program.
False
The equals sign directive (=) may be used for both integer constants and string constants.
False

2
If you are using an integer constant in one of your CS271 programs, which constant method must you use?
=
The byte-ordering scheme which stores integers in memory with the least significant byte at the lowest (first) address is called:
little endian
System endianness affects:
byte-wise ordering
Strings (BYTE arrays) are stored in the same order regardless of system endianness.
True
The byte-ordering scheme which stores integers in memory with the most significant byte at the lowest address (first) is called:
big endian
An SDWORD storing the integer value -540,000 (FFF7C2A0h) is stored in memory on a little-endian system starting at memory address α. What Hex value is stored at each of the following memory addresses?
