Question 1.
What does the zero flag indicate in a processor?
Show hintHide hint
Think about the outcome of arithmetic operations.
Question 2.
Differentiate between explicit and implicit jumps.
Show hintHide hint
Consider if you can see the instruction in the code or not.
3Question 3.
What does the zero flag signal in processor operations?
- A: The last operation was negative
- B: The last operation was zero
- C: The last operation was positive
Show hintHide hint
Think about what happens in subtraction operations.
4Question 4.
True or False: Explicit jumps occur without writing specific jump commands in the code.
- True
- False
Show hintHide hint
Consider what the word 'explicit' means.
Question 5.
Analyze a given code that incorporates both explicit and implicit jumps due to varying conditions of the zero flag. Identify possible errors that may occur.
Show hintHide hint
Pay attention to where the jumps lead based on flag states.
Question 6.
Design an algorithm that utilizes zero flags and includes error checking for cases when flags might not behave as expected.
Show hintHide hint
Consider how you check conditions and schedule program execution.
