How does dynamic allocation work in C++ arrays?

How does dynamic allocation work in C++ arrays?

Dynamic allocation in C++ allows you to create arrays whose size can be determined at runtime using the new keyword.

Can you show me an example of how to allocate and deallocate a dynamic array?

Sure! You can allocate a dynamic array like this: int* arr = new int[size]; and deallocate it using delete[] arr;.

What happens if I forget to deallocate the array?

Forgetting to deallocate can lead to memory leaks, which means the memory remains allocated and is not available for other processes.

Are there any alternatives to using dynamic arrays in C++?

Yes, you can use std::vector from the Standard Template Library, which manages memory automatically.
