Ruby issue: My "gets" function executes before my "puts" statement

I am learning Ruby and I tried a simple code:

system "clear"
print "What is your name?"
name = gets.chomp
puts name
puts "Hello #{ name.capitalize }, how are you?"

and the oupout is ready for the input without showing the print requested. then after I enter a string it show the print:

George
What is your name?George
Hello George, how are you?

Please help. I am confused. Thank you!

I just copied OP's code into my editor (VS Code) and I don't get what OP got. I got

What is your name?George
George
Hello George, how are you?

instead of 

George
What is your name?George
Hello George, how are you?

This is likely caused by output buffering and should be fixed by adding $stdout.sync = true before the first print statement.

Another solution is to call $stdout.flush to manually flush output after the print statement or replace print with puts (but that will add a newline).
