Hi,
I was asked this question in an interview recently. "How do you
move to the 6th byte in a file?" ... My thinking would be to find the
data types in the file, set a base pointer and advance it by 6. I
mean, ptr+6. Another way to ask the same question is how do you move
to the 3rd record in a file (considering that the file is made up of
records).
I told the interviewer that we could do a seek to move to the
specific byte. At that time, the interviewer nodded his head to show
his approval of my answer, but I came to know that he thought there is
a more effective way of doing this. Can anyone throw some pointers on
what that effective way could be?
Regards,
Arvind.
