What is an output

Question

I always see what is the output of this string in the courses but I don't know what it means and it's hard to answer the question

Answer 1

example in java:

System.out.print ("Hello!");

// Hello! is the output

Answer 2

Input is what the program registers from the user, ie. asking the user to type a number. The info flows from out to in.
System.in() <---- input
Output is the opposite, it's what the program shows the user. The info flows from in to out.
System.out() ----> output
Hope this helps.

Answer 3

output is the thing that the program should print

Answer 4

The output could mean the result of the program (no matter what the program does).

Run your program. The result of your program is the output. And what you type when your program run is the input.
