Question

If a random access file contains a stream of Unicode (2-byte) characters, the statement that would move the file pointer to the starting position is:

a) file.seek(0)
b) file.seek(2)
c) file.seek(1)
d) file.seek(4)

Answer 1

To move the file pointer to the starting position of a file containing 2-byte Unicode characters, the correct statement is file.seek(0). This moves the pointer back to the beginning of the file regardless of character size.

Step-by-step explanation:

If a random access file contains a stream of Unicode (2-byte) characters, the statement that would move the file pointer to the starting position is file.seek(0). The file.seek() method allows you to move the file pointer to a specified position within the file. Since file positions are counted in bytes, and the starting byte position is always 0, regardless of the size of the characters in the file, file.seek(0) is used to return to the beginning of the file.
