Mount c instead of d perhaps?

no actually the first time i followed the instructions got from some net source it was successfully runs, i was in fact run few programs already but (same input just until tc or tc.exe) after a day or two i guess just same time when i got trouble with my audio output device that says no "no audio output device connected", when i able to searched for solution for the audio thing and same time when i was still doing my program at dosbox, when i tried to run again my program and there it just went off.. i lost the window of dosbox and when i tried again to mount just same thing and there it goes at the bottom just after "tc or tc.exe" when i press enter "BOSS Stub Version 3.2 Copyright (c) 1990, 1991 Borland International" comes next to the promt... and i wonder now what does that mean that which i cannot again open c++ on dosbox..

thus, mounted d to c was just the right thing, maybe there has just something wrong with it..
please help me to fix it..
looking forward for your answers.. thanks..

What?

well, does my explanation was too complicated ?..sorry for... hhmm, ok.. think i cant just make it to open again..thanks anywy..

Then start all over and follow the original instructions again.
It's not your fault but your English is hard to understand and that you don't seem to end your sentences doesn't help.

ohhh, sorry for my grammar, but i think whats just made it too complicated are the terms of words i uses...i just cant find the right way of explaining it.. 😀 ..sorry..

but back to the issue: i've already tried to uninstalled dosbox and download again, mounted again, but still same it didn't work out... 😖

should i uninstall also the TC?

should i uninstall also the TC?

Yes re-install it and stick to the mountings when running it next time.

Yes, you mentioned a guide you followed. Follow THAT. If that involves installing then do that...

personally i'd rather use a VM instead of dosbox for any C compiling purposes....
