3.4.2. Next Steps in Learning Programming Paradigms

Try these first

1. 1.

   What flag is set when an addition operation results in zero?

   Hint

   Think about what condition indicates no value remains.

2. 2.

   Define the Overflow Flag.

   Hint

   What do you call it when results exceed limits?

3. 3.

   What does the Overflow Flag indicate in arithmetic operations?

   • It indicates a carry
   • It indicates the result is zero
   • It indicates an overflow occurred

   Hint

   What do we call it when computations exceed limits?

4. 4.

   True or False: The Negative Flag is set when the result is positive.

   • True
   • False

   Hint

   Think about how a binary representation defines positivity or negativity.

5. 5.

   If you add two signed integers, -3 and -5, what flags are set?

   Hint

   Think about what the result would be in 8-bit signed integer representation.

6. 6.

   For 8-bit unsigned arithmetic, what would be the output and flags after adding 127 to 130?

   Hint

   Examine how bits wrap around in this case.
