Longest Line

April 18, 2017

Today’s exercise is simple:

Write a program that prints the longest line in a file. If there is a tie for the longest line, you may print any of the longest lines, or all of them, at your option.

There are lots of ways to solve this problem, and I expect that my fun-loving readers will come up with some outlandish solutions, so to make this a sensible exercise we add two rules: First, if you comment you must provide at least two solutions. Second, at least one of your solutions must be “reasonable” in the sense that you would actually use it in a production environment.

Your task is to write a program to find the longest line in a file. When you are finished, you are welcome to read or run a suggested solution, or to post your own solution or discuss the exercise in the comments below.
