Question

Suppose a computer uses 4-bit one’s complement representation. Ignoring overflows, what value will be stored in the variable j after the following pseudo code routine terminates? (show details of all steps of the execution)

0 → j // store o in j

-3 → k // store -3 in k

while k ≠ 0

j = j + 1

k = k – 1

end while

Answer 1

Solution:

• The below tables shows the each and every value of j along with the binary values.
• Also, it shows the value of k for each value of j and its binary representation.
• The table shows for each value of j from 0 to 12, what is the value of k is.

The table for the values of each iteration is provided below:
