minus-square@[email protected]linkfedilink39•2 months 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-squarexigoilinkfedilinkEnglish2•2 months agoDon’t most terminals flush the buffer on newline anyway?
minus-square@[email protected]linkfedilink8•2 months agoIt is the stream itself that is buffered, so the terminal does not handle the contents until the stream is flushed.
minus-square@[email protected]linkfedilink2•2 months agoMaybe, but there is the internal buffer. Also, most I/O happens in files not consoles

minus-square@[email protected]linkfedilink6•2 months agoThe fact that you used the namespace for cout but not for endl inordinately bothers me

minus-square@[email protected]linkfedilink10•2 months agoBoy am I glad I don’t do C++ anymore. That string handling with the overloaded bitshift operator was wild.

minus-square@[email protected]linkfedilink3•2 months agoFrom memory it’s a way to declare a line ending after your string.
What the heck is endl???

Ah, so you’re a println! kinda guy?
