5.1.2. Example of Procedure Call with Nested Procedures

Try these first

1. 1.

   What is the purpose of a procedure call?

   Hint

   Think about why we structure code in functions.

2. 2.

   What is stored in the stack during a procedure call?

   Hint

   Remember the memory locations we discussed.

3. 3.

   What is the first step in a procedure call?

   • Save context
   • Return to caller
   • Jump to procedure

   Hint

   Think about what needs to be preserved before switching tasks.

4. 4.

   Is the stack pointer used to manage saved context during procedure calls?

   • True
   • False

   Hint

   Recall how the stack grows and shrinks during operations.

5. 5.

   Describe a situation in a computer program where multiple nested procedures might lead to a stack overflow. What can be done to prevent this?

   Hint

   Think about how loops might run out of bounds.

6. 6.

   Explain how the system ensures that the program counter points to the correct instruction after executing a nested procedure.

   Hint

   Remember how context is saved and retrieved.
