What are the best practices for using dynamic arrays in C?

When using dynamic arrays in C, it's important to allocate memory properly using malloc or calloc, and to free it when done.

How do I resize a dynamic array in C?

You can resize a dynamic array using realloc. It adjusts the size of the memory block while preserving the existing data.

What should I be careful about when using realloc?

Be cautious with realloc as it can return NULL if it fails, which means you could lose your original pointer if not handled properly.

Are there any performance considerations I should keep in mind?

Yes, frequent resizing can lead to performance issues. It's often better to allocate more space than needed initially.

Can you give an example of dynamic array implementation?

Sure! Here's a simple example: you can create a dynamic array of integers, allocate memory, and then use it in your program.
