Question

We have been assigned the task of selecting an interface language for a disk controller that must count disk reads. In particular, the controller must count how many reads have occurred since the last write to the disk and confirm that the count of reads does not exceed 1,000,000. Two proposals have been made. Method C uses C++ while Method R uses regular expressions. Then

Group of answer choices
A. I would use Method C because Method R would translate into a finite automaton with at least 1,000,000 states.
B. I cannot use Method C because it is not able to keep track of the count of reads.
C. I would use Method C because Method R cannot keep track of the count of reads.
D. I cannot use Method R because regular expressions cannot represent integers.

Answer 1

Method C, which uses C++, is recommended for counting disk reads since regular expressions are not suitable for this task.

Step-by-step explanation:

For the given task of counting disk reads, I would recommend using Method C, which uses C++. Method R, which uses regular expressions, would not be suitable because it would require a finite automaton with at least 1,000,000 states to accurately count the disk reads, which is not practical. Method C, on the other hand, can easily keep track of the count using variables and conditional statements.

The use of regular expressions in Method R makes it unsuitable for counting and keeping track of a large number of events, such as disk reads. Regular expressions are primarily used for pattern matching and text processing. They excel at tasks like searching, parsing, and manipulating strings, but are not designed for counting or tracking numerical values.

In conclusion, Method C, which uses C++, would be the appropriate choice for the given task because regular expressions (Method R) are not suitable for counting and keeping track of the disk reads.
