Code using a library can be much easier to write than code Doing the job instantly with language capabilities, Considerably shorter, tend to be of an increased degree of abstraction, and also the library code is presumably now tested.
If you allow out the default, a maintainer and/or perhaps a compiler may well fairly believe which you intended to deal with all scenarios:
This really is verbose. In bigger code with numerous achievable throws explicit releases become repetitive and mistake-inclined.
Once the examining for overflow and mistake managing has long been added that code will get rather messy, and There's the challenge remembering to delete the returned pointer as well as C-fashion strings that array includes.
Only the first of such motives is essential, so When attainable, use exceptions to put into action RAII, or design and style your RAII objects to by no means are unsuccessful.
