What are the basics of memory management in C?

Memory management in C involves allocating, using, and freeing memory during program execution. It includes concepts like stack vs heap, dynamic memory allocation, and pointers.

Can you explain the difference between stack and heap memory?

Stack memory is used for static memory allocation, while heap memory is used for dynamic memory allocation. Stack is faster but limited in size, whereas heap is larger but requires manual management.

How do I allocate memory dynamically in C?

You can use functions like malloc(), calloc(), and realloc() to allocate memory dynamically in C. Remember to free the memory using free() to avoid memory leaks.

What are memory leaks and how can I prevent them?

Memory leaks occur when allocated memory is not freed. To prevent them, always ensure that every malloc() or calloc() has a corresponding free() call.
