Question

What’s the difference between STDIN.gets() and gets.chomp() in Ruby? Aren’t they both retrieving raw input from the user?

side question: If I want to convert their input into an integer, do I do

myNumb = Integer(STDIN.gets())

and

myNumb = Integer(gets.chomp()) 

Answer 1

Easiest way to do what you describe here is Integer(gets), since Integer() ignores the trailing newline, so chomp is unnecessary. There’s also no need explicitly specify STDIN as the receiver, as that’s what Kernel#gets will do if there are no arguments to the script.
