Weird list print function behaviour. Works if i print “\n”, doesn't work if I remove it

Question

Sometimes c++ plays me big time. I really can\'t think of why this does/doesn\'t work and I\'d be happy if any of you knew.

I call this function once every second on a t

I guess that's because STDOUT is buffered, and printing \n flushes the buffer - see SO on printf \n behaviour
