C++ Array vs Vector: What's the Difference?

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

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

Can you explain the advantages of using vectors over arrays?

Vectors offer dynamic sizing, easier memory management, and built-in functions for manipulation, unlike arrays.

Are there any performance differences between them?

Yes, arrays can be faster due to their fixed size and contiguous memory allocation, but vectors provide flexibility.

When should I use an array instead of a vector?

Use arrays when the size is known and fixed, and performance is critical. Vectors are better for dynamic sizes.
