1.4.2.1. Importance of Sign Flag

Try these first

1. 1.

   What is the role of the sign flag?

   Hint

   Think about how you would describe numbers.

2. 2.

   What does the zero flag signify?

   Hint

   Consider conditions where results can equal zero.

3. 3.

   What is the main function of the sign flag?

   • Indicates if a number is odd
   • Determines if a number is positive or negative
   • Signals an overflow

   Hint

   Think about how signs are represented in binary.

4. 4.

   True or False: The zero flag is set when the result of an arithmetic operation is zero.

   • True
   • False

   Hint

   Recall how comparisons are made in programming.

5. 5.

   Develop a flowchart that illustrates the decision-making process using flags during a simple loop that checks if a counter reaches ten. What will your loop do when different flags are set?

   Hint

   Think about how each flag affects the looping.

6. 6.

   Explain a practical scenario where using flags would optimize a code snippet in a real programming project. What do you think could be the impact of not using flags?

   Hint

   Consider efficiency in programming logic and execution.
