Chapter 13: Problem 30

In __________ file access, the contents of a file may be read in any order.

Short Answer

Expert verified
Answer: Random access.

Step by step solution

01

Identify the file access methods

There are two primary file access methods: sequential access and random access. Sequential access is when the contents of a file are accessed in a linear, sequential manner. In this method, if you need to access a specific data item, you have to read through the entire file from the beginning to reach that data item. This is similar to how a cassette tape works. Random access, on the other hand, allows the contents of a file to be read in any order. This means that you can directly access a specific data item without going through the entire file. This is similar to how CDs or DVDs work.
02

Determine the correct file access method

From the given description, we can determine that the file access method which allows reading the contents of a file in any order is random access. So, in __random access__ file access, the contents of a file may be read in any order.

Design a pseudocode algorithm for reversing the contents of a text file into another file. Assume that the amount of memory is limited, so that you cannot read the entire source file into memory before you start writing it to a second file in reverse order.

In __________ file access, the contents of the file are read in the order they appear in the file, from the file鈥檚 start to its end.

Suppose that you have two text files that contain sequences of integers separated by white space (blank space, tabs, and line breaks). The integers in both files appear in sorted order, with smaller values near the beginning of the file and large values closer to the end. Write a pseudocode algorithm that merges the two sequences into a single sorted sequence that is written to a third file.
