The effect of noexcept on STL operations
The C++ STL gives a rich assortment of data structures and algorithms that greatly simplify programming in C++. Exception safety is a critical aspect of robust C++ programming, and the noexcept specifier plays a pivotal role in achieving it. This section elucidates the impact of noexcept on STL operations and how its correct application can enhance the reliability and performance of STL-based code.
An introduction to noexcept
Introduced in C++11, noexcept is a specifier that can be added to function declarations to indicate that the function is not expected to throw exceptions. When a function is declared with noexcept, it enables specific optimizations and guarantees that make exception handling more predictable. For instance, when an exception is thrown from a noexcept function, the program calls std::terminate, as the function violated its contract of not throwing exceptions. Hence, noexcept is a commitment that a function promises...
