Today I would like to present another new feature of C++11 standard - noexcept specifier. This specifier allows to specify function which does not throw any exception . It should be used be used wherever possible to notify user that function should be throw and it makes such function non-throwable self-documented (similar to usage const ). Its usage is similar to usage const function specifier. The difference is that while const function tries to modify data it we have compilation error. In case of noexcept function throws any exception, code compiles, however it std::terminate function is invoked when we achieve throwing exception in such function. To understand it better, take a look on below example: Output of this example is: In point I, we are defining function as non-throwable using noexcept specifier. Such function should not throw, however in our example we are throwing exception in order to present what happens when noexcept function tries to throw except...
