Heap sorting can be used as real-time sorting, is the original sort, does not require additional space, time complexity is O (NLGN), the best worst-case average is this, but is not stable ordering, the following is the C language implementation code:

I recently used a named pipe in C # in a project, so write a summary memo here.Why use Named pipes? In order to achieve data exchange between the two programs. Assume the following scenario. On the same PC, program A and program B need data

Modifiers are used to qualify types and declarations of type members from the definition you can see that there are two types of functions: access modifiers and declaration modifiers 1. Access modifiers (5) access modifiers describe public publicly

Objective:Process-oriented and object-oriented. to put it simply, the process is to analyze the steps needed to solve the problem, and then use the function to implement these steps one step at a time, using a single call in turn. Object-oriented
