Welcome back! In part 1 I discussed how std::string and std::vector interoperate with C, including with the C standard library qsort call. We also discovered that the C++ std::sort is 40% faster than C qsort because C++ is able to inline the comparison function. In this part we continue with further C++ features that you can use to spice up your code ’line by line’, without immediately having to use all 1400 pages of ‘The C++ Programming Language’.
