Which of the following is the most efficient approach to reading values from a file?
Using the FOR...TO...NEXT loop with an array.
Using a REPEAT...UNTIL loop.
Using the WHILE...DO...ENDWHILE loop.
Using the INPUT statement.
설명
FOR...TO...NEXT loops are used in the most efficient way to iterate over an array. The end and start values are known, and are easy to calculate the amount of iterations necessary for the loop.
