I thought it would just show 10.126 twice.

Wait, why does it round to 10.12?

I don't think there's a compilation error, so it has to be one of the outputs. I lean towards D, but I could be wrong.

I feel like the answer is B, but I might be mixing it up with another question about formatting floats.

I remember something similar where setprecision affected the output, but I can't recall if it rounds up or down.

I think the output will show the float value with two decimal places, but I'm not sure if it rounds or just truncates.

I'm pretty confident the answer is C. SHA-1 produces a 160-bit digest and is similar to the older MD5 algorithm in some ways.

Based on the information provided, I believe the solution is to alter the user KING to be IDENTIFIED EXTERNALLY. That should allow the OS authentication to work.
