What is the difference between arrays and vectors in C++?

What is the difference between arrays and vectors in C++?

Arrays are fixed-size and have a static memory allocation, while vectors are dynamic and can resize.

Can you explain how memory management differs between the two?

Sure! Arrays allocate memory at compile time, while vectors manage memory at runtime, allowing for dynamic resizing.

Are there any performance differences I should be aware of?

Yes, arrays can be faster due to their fixed size, but vectors offer more flexibility, which can be beneficial in many scenarios.

When should I use one over the other?

Use arrays when the size is known and fixed, and use vectors when you need dynamic sizing or additional functionalities.
