C++

1. Start by implementing a network library yourself, or choose an already open Source network library. For example: Muduo, libevent, boost ASIO and so on.2. Implement core functions: connection management, message management, timer, event mechanism,

opening and closing file files* fopen (Const Char*path,Const Char*mode);intFclose (FILE *stream) fopen opens a file named path in mode mode fopen returns a file pointer error, FOPEN returns NULL, and sets errno to the appropriate value mode mode

C + + retains the struct of the language and expands it. In the C language, a struct can contain only data members and cannot contain member functions. In C + +, a struct is similar to class, and can contain both a data member and a member

Wrote a string copy function yourself: 1#include 2#include 3 Char*mystrcpy (Char*des,Char*Ser)4 { 5ASSERT ((des!=null) && (ser!=NULL)); 6 Char*adress=des; 7 intnum=0; 8 while(*ser!=' /') 9 {

1. put C + + as multiple sub-languages ( C , C + + , template C + + , STL ) Combination of The guidelines for efficient programming vary for different sub-languagesfor example: for C + + and template C + +, the efficiency of the reference is high.

64. Common sorting algorithm (order):Before the reference is too bad, the algorithm is not clear, comments have errors, re-reference other materials.When the number to be sorted is large, a sorting algorithm with a time complexity of O (NLOGN)

For a time when interfaces are flooding, it is necessary for a programmer to understand and handle interfaces!In the docking when the other sent over the document, you need to look carefully, there are questions such as encryption, etc., need to be

The WHERE clause is used to specify type constraints that can be used as variables for type parameters defined in a generic declaration.1. Interface constraints.For example, you can declare a generic class MyGenericClass, so that the type parameter

This property represents the runtime state of a thread, and in different cases there are different values, and sometimes we can design the program flow by judging the value.The value of the ThreadState property is as follows:aborted: thread has
