minus-squareallywilson@lemmy.mllinkfedilinkarrow-up3·2 天前From memory it’s a way to declare a line ending after your string.
minus-squarevapeloki@lemmy.worldlinkfedilinkarrow-up40·2 天前std::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 天前Don’t most terminals flush the buffer on newline anyway?
minus-squareClemaX@lemm.eelinkfedilinkarrow-up8arrow-down1·2 天前It 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 天前Maybe, but there is the internal buffer. Also, most I/O happens in files not consoles
minus-squareHellfire103@lemmy.caOPlinkfedilinkEnglisharrow-up10·edit-22 天前Instead of this: cout << "Hello world.\n"; You can do this: cout << "Hello world." << endl;
minus-squareReversalHatchery@beehaw.orglinkfedilinkEnglisharrow-up1·2 天前something has replaced your lessthan signs with their HTML counterparts. such a silly thing to do in a code block
minus-squarefubbernuckin@lemmy.dbzer0.comlinkfedilinkEnglisharrow-up3·2 天前I think that’s client side. Doesn’t happen for me.

minus-squareDaedskin@lemm.eelinkfedilinkarrow-up5·20 小时前The fact that you used the namespace for cout but not for endl inordinately bothers me

minus-squareunlawfulbooger@lemmy.blahaj.zonelinkfedilinkarrow-up12arrow-down1·2 天前Boy am I glad I don’t do C++ anymore. That string handling with the overloaded bitshift operator was wild.
What the heck is endl???

Ah, so you’re a println! kinda guy?
