What are the differences between std::vector and array in C++17?

What are the differences between std::vector and array in C++17?

In C++17, std::vector is a dynamic array that can resize, while arrays have a fixed size determined at compile time.

Can you explain the advantages of using std::vector over arrays?

Sure! std::vector offers automatic memory management, dynamic resizing, and various member functions for easier manipulation.

Are there any performance differences between them?

Yes, std::vector may have overhead due to dynamic memory allocation, while arrays are faster for fixed-size data due to their simplicity.

When should I prefer using arrays instead of std::vector?

You should prefer arrays when you know the size at compile time and need maximum performance with minimal overhead.
