C++: Vector vs Array

What's the difference between a vector and an array in C++?

In C++, an array is a fixed-size collection of elements, while a vector is a dynamic array that can resize itself.

When should I use a vector instead of an array?

Use a vector when you need a resizable array, especially when the size of the data is unknown at compile time.

Are there any performance differences between them?

Yes, arrays have better performance for fixed sizes, while vectors may have overhead due to dynamic resizing.

Can I store different data types in a vector?

No, vectors in C++ can only store elements of the same type, similar to arrays.

What about memory management for both?

Arrays have static memory allocation, while vectors manage memory dynamically, handling allocation and deallocation automatically.
