Vectors is sequence containers representing arrays that can change in size.Just like arrays, vectors use contiguous storage locations for their elements, which means this their elements can also be Accessed using offsets on regular pointers to its

Multiple inheritance in C + + inevitably occurs with diamond inheritance, that is, the two base classes of inheriting classes are also inherited classes of the same base class, and when an object is created, what order do they call the

This is about the application of pointers in algorithms.Direct Select sortEach sorting algorithm is a handy feature of pointers that point to each element for exchange, etc.The basic idea here is to treat the sorting records for n-1 times.I
