1.2. Unit Summary

Try these first

1. 1.

   What is the purpose of conditional instructions?

   Hint

   Think about how 'if' statements work in programming.

2. 2.

   What do flags in a CPU indicate?

   Hint

   Recall the types of outcomes a math operation can have.

3. 3.

   What do conditional instructions modify?

   • The hardware architecture
   • The program execution flow
   • The CPU performance

   Hint

   Think about changes in execution paths.

4. 4.

   True or False: Unconditional branches change execution flow only based on conditions.

   • True
   • False

   Hint

   Consider scenarios where conditions do not apply.

5. 5.

   Design a small program that continuously takes user input until they enter the number 0, utilizing flags to manage the loop.

   Hint

   Remember to declare your loop condition clearly.

6. 6.

   Calculate what happens in a sequence of arithmetic operations followed by a series of conditional jumps. What would the final program counter value be if certain conditions are met?

   Hint

   Be meticulous; each flag change can affect the direction of your code execution.
