C++ noexcept: Purpose & Performance Boost

In C++, noexcept is a keyword used to indicate that a function will not throw any exceptions.

Using noexcept can improve the performance of the program by informing the compiler that there is no need to generate extra code to handle exceptions, thus avoiding the overhead of the exception handling mechanism.

Furthermore, noexcept can also assist programmers in better designing and maintaining code, as it enforces the behavior of functions, preventing unexpected exceptions and improving the reliability and maintainability of the code.
