Consider the following common task done repeatedly: • Read the next input (x = read()) • If the input is not valid (valid(x)), exit the loop • Print the input read (print(x)) • Repeat the loop Using C++ syntax: Write the loop above using a pretest loop, posttest loop and a user-located loop control mechanism. From the three which one is more readable and why?
