Recently and the server colleague to deal with a game data problem, found that the server Lua script floating point data in the server C + + code is called the error may occur. Similarly, if the client uses Lua's built-in library of functions to

The recent demand forced, finally embarked on the legendary Lua .After 4 days, I finally figured out how to use it.Let's not talk about the details, just say how the project runs.Preparatory workWe need a series of tedious prelude.tolua++: This is a

The first header file defines the commonly used functions of the linked list:typedef struct NODE {int data;struct node* next;} Node;class linklistutil{public:linklistutil (); ~linklistutil ();//createnode* createbyarray (int arr[], int len); int

The use of & identifiers for both addresses and references makes it easy to misunderstand.In the case of C + +. References are only knowledge in C + +, and the address is shared.Take address:In line 6th I define a pointer to the INT type P, use &a

the definition of a pointer variable:the variable that holds the address is called the pointer variable1. The general form of defining pointer variables is as follows:type name * pointer variable name 1,* pointer variable Name 2, ... * pointer

Method One:#include #include Double fun (int m){int n,i,k;double s = 0.0;for (n=3;n{K = sqrt (n);for (i=2;iif (n%i==0) break; If n is composite, end this layer for loopif (i>=k+1) s + = sqrt (n); I can not be exhausted by N, then N is prime

C++11 added a number of convenient algorithms, these new algorithms make our code more concise and convenient to write, here just to enumerate some of the commonly used new algorithms, as a summary, more new algorithms readers can refer to http://en.

Some casual ideas about the design philosophy of the C ++ language system (to be continued)For a static language, its essential goal is to properly operate the data and obtain the expected value. Specifically, you need to: (1) define the data type,

C ++ and variables and constants in Java In fact, this is an important difference between C ++ and Java. The C ++ compiler does not perform initialization checks on local variables, so it is easy to forget to initialize a variable in C ++. In this
