Ruby File Reading and Writing

Complained todayThe blog has not been updated for many days, which affects reading mood. I just need to start it. ^_^

# Part One

Afile = file. New ("C: \ 1.txt"," W ")

Afile. Puts "The 1"

Afile. Puts "The 2"

Afile. Close

 

# Part Two

Afile = file. New ("C: \ 2.txt"," W ")

Puts "The 1"

Puts "The 2"

Afile. Close

I'm bored. I took a look. Ruby How to read and write files and prepare write segmentsCodeTo generate test data. There are two sections of code above. Can you see the difference? Well, one is used. Afile. Puts The other one is Puts . Only Part One The code will write the string into the document, and Part Two The Code only prints the string on the screen. I wonder if it is not specified I/O In the case Ruby Use Standard I/O As the default input and output. If you are interested, you can directly Copy This code goes Ruby Of IDE To see the effect.

In addition, note that the format of the file path is "\" rather than "\".
