How can I handle errors in dynamic memory allocation?

You can handle errors in dynamic memory allocation by checking if the pointer returned by malloc or calloc is NULL.

What should I do if the allocation fails?

If allocation fails, you should free any previously allocated memory and handle the error gracefully, possibly by logging it.

Are there any best practices for memory allocation?

Yes, always check for NULL after allocation, use smart pointers if available, and ensure to free memory when done.

Can you give an example of error handling in C?

Sure! Here's a simple example:

int *arr = malloc(size * sizeof(int));
if (arr == NULL) {
    fprintf(stderr, "Memory allocation failed!\n");
    exit(1);
}
