Question-32. How is memory managed in Simula?
Answer-32: Simula relies on garbage collection for memory management.
Question-33. What is the significance of dynamic objects in Simula?
Answer-33: Dynamic objects in Simula allow objects to be created and destroyed during runtime.
Question-34. What are "processes" in Simula?
Answer-34: Processes in Simula represent independent units of execution for simulations.
Question-35. How do you define a procedure in Simula?
Answer-35: Procedures are defined using the PROCEDURE keyword followed by their name and body.
