How did you fill the 2nd table?

Not sure I understand.....table 1 and 2 had some information in it already......only 3 was completely empty. I do suspect I might have an issue with table 2, but Im not sure.

It looks like Table 2 should have had C, B, E as its headers, not C, D, E. Then, use standard logic to fill in Table 3.

Hmmmm that makes sense as I struggled to figure out why it was split that way.......I will bring this up with the tutor as well.

Ok so no word from the tutor yet, but I decided to change it from a D to a B and finished the table......does this look better?

A+

BUT . The tutor will be looking on this site, so C- , unless you explain to them why the table changed.

I agree. And Table 3 only needs the first 4 lines, as the next 4 lines are repeats. And, to be picky, the D and E columns would normally be listed, in order, as 00, 01, 10, 11.

Thanks guys....

@andrewmm LOL yeah I did mention in the start of the assignment that I changed it as it didn't quite make sense.

@shortout yes I did initially stopped at the first 4 lines in Table 3 because of the repeat, but then thought Id rather complete it not to lose points just in case.

Thanks again guys for the input and well received.
