What is the significance of the "endl;"?

Question

Is it different than "\n"?

Answer 1

Practically no. \n can be inserted anywhere between " " so you can make new lines inside instead of writing << endl over and over again

Answer 2

Yes, they're different. "\n" is a string member of size 1. But endl is a object that adds "\n" to you output.
Summary:
In practical reasons "\n" is faster.

Answer 3

1 символ, я имел ввиду:)
