# En gång för alla...

## #1 — zmodem, 2002-10-10T19:15Z

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.
