How can I improve vector performance in C++?

To improve vector performance in C++, consider using reserve() to allocate memory upfront, minimizing reallocations.

What about using std::vector vs std::array?

std::vector is dynamic and resizes, while std::array is fixed-size and can be more efficient for small, known sizes.

Are there any specific algorithms that work better with vectors?

Yes, algorithms like std::sort and std::copy are optimized for std::vector, making them efficient for operations.

How does memory allocation affect performance?

Frequent memory allocations can slow down performance due to fragmentation; using reserve() helps mitigate this.

Can you give an example of using reserve()?

Sure! You can use it like this: myVector.reserve(100); to allocate space for 100 elements upfront.
