First, outlined in my participation in a number of projects, we use LIBMYSQL operation MySQL database, and is the source code is reused, in many projects there are many sets of identical or similar source code, such a reuse way to the development

Directly on the code:#includevoid Fun (int *a[],int m,int N)//{printf ("%d\t", *a);//[0][0]/*int e[2][2][2]={8,7,6,5,4,3,2,1};int *f,***g;g=e;f=e;//a warning, but not an error.printf ("%d\n", *f);*/}/* Explanation:The int *a[2] in fun () means that

Very early write file read and write operation under Linux system, read data from file#include int readinfofromfile (const char *strfile) {FILE *fp;char CH;FP = fopen (strfile, "R");// Read-only way to open the file if (fp==null) {perror ("fopen");//

Design patterns in the field of software provide developers with an effective way to use expert design experience. The design pattern uses the important characteristic of object-oriented programming language: encapsulation, inheritance, polymorphism,

the best way to find a program error is to execute the program. During the execution of the program, we use our eyes or the tools of automated testing such as assertions and subsystem conformance checks we write to discover errors. While assertions

Try the following code:#include using namespace Std;void f (int &a){Cout }void g (const int &a){cout }int main (){int a = 3, b = 4;F (A + B); compile error, passing the temporary variable as a non- const reference parameterG (A + B); OK, passing

Recently COCOS2DX learning Jam, the general copy code I do not want to write up, but want to sample also want me dizzy ... To relax the brain and adjust the state, start learning Lua. Lua's grammar learning is relatively simple, learning JavaScript

Article 01: Treat C + + as a language federalC + + is a multi-paradigm programming language, one that supports both process-oriented, object-oriented, functional, generic, and meta-programming forms.Treat C + + as a few sub-languages:Traditional C:

summarize the storage categories of variables in C + + and the scope of variables .(1) The storage class of the identifier determines the time the identifier exists in memory (we can understand that the identifier is the symbol that determines a

The following are some examples of the basic features of C + + that are compiled and run by the author in Ubuntu system, including classes, structs, constructors, destructors, overloads of functions, this pointer, class inheritance, virtual

Standard C-language preprocessing requires defining some object macros, with the name of each of the predefined macros beginning and ending with one or two underscore characters that cannot be undefined (#undef) or redefined by programmers. The

What C ++ list size () comes to mind, listsize Valid STL focuses on listing in an Item. size () is an O (n) efficiency. At that time, I just wrote down the efficiency. Later I saw some people in csdn encountered a pitfall in the actual project. I
