What are the performance improvements in C++11 std::string?
C++11 introduced several optimizations for std::string, including small string optimization and move semantics.
Can you explain small string optimization?
Small string optimization allows std::string to store short strings directly in the object, reducing heap allocations.
How does move semantics enhance performance?
Move semantics allow resources to be transferred rather than copied, which significantly speeds up string operations.
Are there any benchmarks comparing C++11 std::string to previous versions?
Yes, benchmarks show that C++11 std::string can be significantly faster, especially for operations involving short strings.
