minus-squarevapeloki@lemmy.worldlinkfedilinkarrow-up41arrow-down1·2 days agostd::endl is used in output streams in C++ to end the line, using the os specific line termination sequence, and flush the buffer. The later one is a performance issue in many cases, why the use of "\n" is considered preferred
minus-squarexigoi@lemmy.sdf.orglinkfedilinkEnglisharrow-up3arrow-down1·2 days agoDon’t most terminals flush the buffer on newline anyway?
minus-squareClemaX@lemm.eelinkfedilinkarrow-up8arrow-down1·2 days agoIt is the stream itself that is buffered, so the terminal does not handle the contents until the stream is flushed.
minus-squarevapeloki@lemmy.worldlinkfedilinkarrow-up2·2 days agoMaybe, but there is the internal buffer. Also, most I/O happens in files not consoles
