Complete Modern C++ - Exception Handling - Part VI - (noexcept Keyword in C++11)

The video tutorial explains the noexcept specifier in C++, which is used to inform the compiler that a function does not throw exceptions, allowing for optimized code generation. It discusses when to use noexcept, emphasizing that it should only be applied to functions that are guaranteed not to throw exceptions. The tutorial provides examples, explains the noexcept operator, and offers guidelines for using noexcept in functions, move operations, and destructors. It highlights the importance of marking move constructors and destructors with noexcept to improve performance when using standard containers.
