Covering and hiding in C + + classes has always been a place where mistakes are easy to understand, and then I'll explain in detail where the difference is.Overrides refer to subclasses overriding the parent class function (overridden), which is

C language implements basic data structure (ii) linked list (including three simple sorting algorithms for linked lists)

C language Simulation implements STRSTR function, Strrstr function

Strstr and Strrstr have been relatively difficult in the string, but as long as we are good at analysis, the anatomy of the string, it will be very easy. In fact, the process of learning code needs us to calm down to analyze, understand. function
