Re: Scanf is not working in posix sample



Jason,

it might have been late when you tried out this code, but... scanf does
not work that way. You can't put a prompt text into the first parameter
of scanf. Try out this one: replace your scanf line with:

	printf("Eingabe: ");
	scanf("%d",&nummer);

wkr,
Thomas.
