Cov haujlwm feof() yog siv mus xyuas qhov kawg ntawm ntaub ntawv tom qab EOF . Nws kuaj qhov kawg ntawm ntaub ntawv qhov taw qhia. Nws rov qab tsis yog xoom tus nqi yog ua tiav lwm yam, xoom.

Ib yam li ntawd, kuv yuav paub li cas yog tias EOF mus txog hauv C ++?

Koj ua tau ntes thaum qhov kawg ntawm ntaub ntawv yog mus txog los ntawm kev siv cov tswv cuab ua haujlwm eof () uas muaj cov qauv: int eof (); Nws rov tsis yog xoom thaum qhov kawg ntawm ntaub ntawv ua tau mus txog , txwv tsis pub nws rov xoom.

Koj sau EOF hauv C++ li cas?

Tiag tiag hauv C++ tsis muaj lub cev EOF cim sau rau ib cov ntaub ntawv siv fprintf() lossis ostream mechanisms. EOF yog I/O mob los qhia tias tsis muaj ntaub ntawv ntxiv los nyeem.
