How does array allocation work in C++?

How does array allocation work in C++?

In C++, array allocation can be done either statically or dynamically. Static allocation is done at compile time, while dynamic allocation is done at runtime using the new keyword.

Can you explain the difference between static and dynamic allocation?

Sure! Static allocation means the size of the array is fixed at compile time, while dynamic allocation allows you to allocate memory during program execution, which can be resized.

What happens if I try to access an out-of-bounds index?

Accessing an out-of-bounds index in a statically allocated array leads to undefined behavior, while for dynamically allocated arrays, it can cause a runtime error or crash.

How do I properly deallocate a dynamically allocated array?

You can deallocate a dynamically allocated array using the delete[] operator followed by the array name.
