2.2.3. Label Instructions

Try these first

1. 1.

   What does signed arithmetic involve?

   Hint

   Think about how numbers are represented.

2. 2.

   What happens when the addition of two numbers exceeds the maximum value representable?

   Hint

   Consider what overflow means in arithmetic.

3. 3.

   What is the primary function of the overflow flag?

   • Indicate a zero result
   • Indicate the need to carry
   • Signal an arithmetic overflow
   • Indicate a negative result

   Hint

   Think about what happens when adding large numbers.

4. 4.

   True or False: The carry flag is important in signed arithmetic.

   • True
   • False

   Hint

   Consider the context of signed numbers.

5. 5.

   Create a signed addition algorithm that tracks overflow and adjusts the values accordingly if the result exceeds the limits.

   Hint

   Consider scenarios with multiple bounds.

6. 6.

   Develop a small program that utilizes labels for managing multiple looping conditions. How would you structure it with various flags?

   Hint

   Think about what each loop needs to accomplish.
