[comp.lang.c++] Possible Turbo C++ stream I/O bugs

helmke@babbage.csus.edu (Michael Helmke) (03/03/91)

I have encountered the following problem in Turbo C++ 1.00

#include <iostream.h>
#include <iomanip.h>

void main(void)
{
	int value;

	cin >> hex >> value;
}

if the above is run with a watch window attached to value, I can
read in "pseudo" hex numbers.  7f becomes 75, 7e becomes 74, etc.
the rule seems to be, if a letter a..f is encountered during hex
conversion, convert it to 0..5.  This is hardly useful...
Has anyone else run into problems like this?
I have had some other more difficult to describe problems with the stream
library and am beginning to suspect it has many bugs in it.

Any solutions, patches, or official and unofficial bug lists would
be greatly appreciated...

thanks in advance.
