what is the difference between endl and \n

Answer 1

Yes, they're different.

"\n" is just a string of length 1 that gets appended to stdout.

std::endl, instead, is an object that will cause to append the newline character ("\n") AND to flush stdout buffer. For this reason it will take more processing.
