C Pointers, Memory, and Low-Level Concepts
·
Module 1
C Memory Model and Data Lifetime
1
C Program Memory Layout
Diagram the memory layout of a C program (text, data, BSS, stack, heap) and identify where different variable types are stored.
2
Understanding the Function Call Stack
Explain the function call stack mechanism, including stack frames, local variables, and return addresses.
3
Understanding C Storage Classes: Scope & Lifetime
Distinguish between auto, static, extern, and register storage classes, predicting variable lifetime and scope in code snippets.
4
Understanding `static` in C: Locals, Globals, and Functions
Explain how the `static` keyword's behavior differs for local variables, global variables, and functions.
Understanding `volatile`: Compiler Hints and Bug Avoidance
Explain what `volatile` signals to the compiler and identify scenarios where its omission causes bugs (e.g., hardware registers, ISR-shared variables).
`const` and `volatile`: A Dual Perspective on Variable Qualification
Analyze code combining `const` and `volatile` to explain why both can apply to the same variable (e.g., a read-only hardware status register).
