Question

How will you construct a loop in Visual Basic to read delimited data from a sequential file?
(1)Create a sentinel-controlled loop using the EndOfData as the sentinel value.
(2)Create a counter-controlled loop using the number of records as the exit value.
(3)Create a sentinel-controlled loop using the field delimiter as the sentinel value.
(4)Create a counter-controlled loop using the number of fields as the exit value.

Answer 1

Number 1 should be the correct answer. Typically you don't know the number of records in a file ahead of time so you can't you can't use a counter to end the loop. And using the field delimiter will not help you get the to the End Of File designation either. Leaving #1 as the only correct answer.
