     the static memory, stack memory and memory pool we used so far, static memory is used to hold local static objects, class static members, and members defined outside any function. Stack memory is used to hold non-static members defined inside

Sorting an unordered array (sequence) is arranged according to certain rules, and the common rule is to follow the order from big to small or from small to large. The sort discussed in this article refers to this situation in order from small to

First, the problem introducedAbout the new and delete operators in C + +,We know that these two operators must exist in pairs to avoid memory leaks.This is considered common sense when learning, however, it is often difficult to actually write code

Principle: Control changes to the data as much as possible, if you can predict that the data will not or should not be changed, it is necessary to control it, and do not expect the caller to use this data will not change its value.If the parameter

Size_t and size_type, size_tsize_type Size_t and size_type are defined to be independent of them, because for example, int Is 2b on one computer and 4b on the other computer, in this way, the program portability is troublesome. To solve this
