4.1.3. Unit Objectives

Try these first

1. 1.

   What is modular programming?

   Hint

   Think about breaking down tasks into smaller, manageable parts.

2. 2.

   Why is the stack important in procedure calls?

   Hint

   Consider the sequence of function executions.

3. 3.

   What type of programming structure does modular programming emphasize?

   • Sequential
   • Modular
   • Linear

   Hint

   Think about how programs are organized.

4. 4.

   True or False: The stack is essential for managing return addresses during function calls.

   • True
   • False

   Hint

   Consider the role of the stack in nested function calls.

5. 5.

   Design a C program that uses modular programming concepts and detail how you would implement this in assembly for the call and return functions.

   Hint

   Focus on stack pointers and data organization in procedures.

6. 6.

   Create a flowchart representing a stack during multiple nested function calls and returns.

   Hint

   Draw sequentially from the main program to nested calls, noting what data is pushed and popped.
