File Object Management: Optimistic Approach

How many file objects would you need to create to manage the following situations?

a) To process four files sequentially.

b) To merge two sorted files into a third file.

Answer:

To manage the given situations, you would need a total of three file objects. One file object would be required to process four files sequentially, and two file objects would be needed to merge two sorted files into a third file.

To process four files sequentially, you can use a single file object that iteratively opens each file, reads its content, performs any necessary processing, and then moves on to the next file. This approach allows you to process the files one by one without the need for multiple file objects.

To merge two sorted files into a third file, you would need two file objects. The first file object would be used to open and read the content of the first sorted file, while the second file object would be used to open and read the content of the second sorted file. You can then compare the data from both files, merge them in the desired order, and write the merged data into a third file using a separate file object.

Final answer: You need four file objects to process four files sequentially and three file objects to merge two sorted files into a third file, totaling seven file objects for both operations.

Explanation: To answer the question regarding the number of file objects needed:

a) To process four files sequentially, one would need to create four file objects, one for each file. This is because each file needs to be opened, processed, and then closed before moving on to the next file.

b) To merge two sorted files into a third file, you would need three file objects. Two of these file objects are for reading the files you are merging, and one file object is for writing the merged data to the third file.

Therefore, a total of seven file objects would be necessary for both operations: four for processing the files sequentially and three for the merging operation.
