De första frågorna som dykt upp på programmeringskursen nu är hur man gör schyssta grejor i konsolen...
Typ, rensar skrämen, byter för- och bakgrundsfärg, flyttar markören o.s.v....
Coper här har redan varit igång och frågat lite :bire
Hur är det, kan man lösa detta med nån sorts escape-koder och i så fall hur? Finns det nåt schysst library man kan använda, det lär väl knappast ingå några användbara prylar för användamålet i STL?
Tacksam för all info jag kan få :)
Är det console i *nix är ncurses ett vettigt lib med en hel del features.
Annars är conio.h nog det du söker.
STL har inget med presentationen (kosmetikan) att göra.
