1> First line of file
2> Second line of file
3> Third line of file
File.open("Solution103.rb").each_with_index { |line, count|
puts "#{count} > #{line}
}
puts "#{count} > #{line}
}
int counter = 0;
// If the file is large, you would want to buffer this instead of reading everything at once
foreach (string line in System.IO.File.ReadAllLines("filename.txt"))
{
Console.WriteLine("{0}> {1}", ++counter, line);
