1.4.5. Overflow Flag

Try these first

1. 1.

   What is the purpose of an overflow flag?

   Hint

   Think about what happens during arithmetic operations that could go beyond a certain value.

2. 2.

   How does a conditional instruction behave in relation to flags?

   Hint

   Recall how decisions are made in programming.

3. 3.

   What does the overflow flag indicate?

   • An operation is successful
   • An operation exceeds limits
   • An operation is irrelevant

   Hint

   Think about the result of large calculations.

4. 4.

   True or False: Conditional instructions can execute without evaluating any flags.

   • True
   • False

   Hint

   Recall how decisions are made in programming.

5. 5.

   Write a function using pseudo-code that keeps adding integers until an overflow occurs. Include checks for the overflow flag.

   Hint

   Focus on how to check for overflow during addition operations.

6. 6.

   Critique a code snippet that fails to handle overflow correctly and suggest improvements.

   Hint

   Consider how to safely manage large sums for reliable operations.
