line feed ' \ n ' and carriage return ' \r'

As the name implies, the line break is another line, the carriage return is the beginning of the line back, so we usually write a file carriage return should be exactly called carriage return newline character

' \ n ' 10 line break (newline)
' \r' 13 return vehicle (return)

Can also be expressed as ' \x0a ' and ' \x0d '. (16 binary)

Under Windows System, the carriage return newline character is "\r\ n". But there is no "\r" symbol in Linux and other systems.

When parsing text or other format file content, often have to encounter the decision to enter the line of the place, this time should pay attention to both "\R\ n" and also determine "\ n".

You can get a line when you write a program, trim it off ' \r', and get the string you need.
