ANS: F PTS: 1 REF: 173 . For consistent semantics, a clear separation between loops where the iteration count is known before the execution of the loop (for-loops), and loops where the iteration count is not known before execution (while-loops) should be made. In this book there are some do it yourself questions which are much more complicated than the examples. In case of the second iteration, the file gets downloaded into the folder but the filename doesn't get printed, the second while loop involved goes into indefinite loop. indefinite loop. Thus as the while loop conditions are based on these variables, you will never exit your loops. A (n) _____ is any numeric variable you use to count the number of times an event has occurred.

Your code could be simplified to something like:Answer: In some cases, a loop control variable does not have to be initialized. Strictly speaking the While Loop is a Do While Loop, because the stop condition is checked at the end of a loop, which requires the subdiagram to execute at least once. Sometimes this can be dangerous as it can make a program appear to be frozen to the user. For your sample it's easy to fix it when you only accept one line from a pipe. (false) false ) 29.
