How can I optimize performance in C++ using vectors?

How can I optimize performance in C++ using vectors?

To optimize performance with vectors in C++, consider using reserve() to allocate memory upfront, minimizing reallocations.

What about using std::vector vs. raw arrays?

std::vector provides automatic memory management and bounds checking, while raw arrays are faster but less safe.

Are there specific algorithms that work better with vectors?

Yes, algorithms like std::sort and std::copy are optimized for use with std::vector, leveraging its contiguous memory.

How can I measure the performance improvements?

You can use profiling tools like gprof or Valgrind to measure execution time and memory usage before and after optimizations.
