What are the best practices for using std::vector in C++?

What are the best practices for using std::vector in C++?

Some best practices include using reserve() to avoid reallocations, and using emplace_back() for efficiency.

When should I use std::vector instead of other containers?

Use std::vector when you need dynamic array functionality, fast random access, and when the size of the container may change.

How can I avoid memory issues with std::vector?

To avoid memory issues, ensure you manage the size properly, use reserve() to allocate memory in advance, and avoid unnecessary copies.

Can you explain the difference between std::vector and std::array?

std::vector is dynamic and can change size, while std::array is a fixed-size array known at compile time.
