What is the difference between dynamic and static allocation in C++?

What is the difference between dynamic and static allocation in C++?

In C++, static allocation occurs at compile time, while dynamic allocation happens at runtime using the 'new' keyword.

Can you give me an example of each?

Sure! Static allocation can be done like this: int arr[10]; and dynamic allocation like this: int* arr = new int[10];.

What are the advantages of using dynamic allocation?

Dynamic allocation allows for more flexible memory usage, as you can allocate memory as needed and free it when done.

Are there any downsides to dynamic allocation?

Yes, dynamic allocation can lead to memory leaks if not managed properly, and it may also be slower than static allocation.
