Can you explain the importance of the "volatile" keyword in C?

Hard Difficulty

Hard questions require advanced understanding and critical thinking. Here, your problem-solving skills are key, as these questions often involve complex scenarios needing in-depth analysis and well-structured responses.

Embedded Coding question

Embedded Coding questions assess your ability to program for resource-constrained devices. Show your understanding of hardware interfaces, memory management, real-time constraints, and efficient algorithm implementation for embedded systems.

Here's a Hint

Focus on how volatile prevents compiler optimizations for variables that can change unexpectedly, especially in embedded systems with memory-mapped I/O or interrupt handlers.
