Kendynet constructs an asynchronous redis access service, kendynetredis Recently, I started to develop a mobile game server on kendynet. The game type is survival challenge. The data structure and type to be stored are relatively simple. So I chose

Object-C, NumberDemo, and StringDemoTwo demos were written at night.The first is a demo string, and the second is a demo array and a variable array.Only a few basic methods and basic statements are used.NSString String object, NSNumber,

C language: Output multiplication table # Include int main () {int I = 0; int j = 0; for (I = 1; I  Output result: 1*1 = 12*1 = 2 2*2 = 43*1 = 3 3*2 = 6 3*3 = 94*1 = 4 4*2 = 8 4*3 = 12 4*4 = 165*1 = 5 5*2 = 10 5*3 = 15 5*4 = 20 5*5 = 256*1 = 6 6*

C language: Only one digit in a group of data appears once. (Bitwise Operation)Program: # Include int main () {int arr [] = {1, 3, 1, 4, 9, 4, 5}; int I = 0; int len = sizeof (arr) /sizeof (arr [0]); for (I = 1; I  Result: The singular value is 9

Simulation of memcpy and memmove functions in C LanguageHere, the simulation implementation of memcpy and memmove functions requires the use of a null pointer to pass the parameter, and then forced type conversion to char type, using the size_t

Cainiao talks about two-dimensional arrays, and cainiao two-dimensional arrays. Every time I encounter a two-dimensional array in the C language, it is a special headache. It is not difficult to use it, but I don't know what its array name

C language: Adjust the array so that all the odd numbers are in front of the even number. #define _CRT_SECURE_NO_WARNINGS 1#include#include#include void even_old_number(int *arr, int len){ assert(arr); int i = 0; int j = 0; int tmp =

Differences between macros and functions in C LanguageI. Code Length: the macro is completely replaced and inserted into the program to make the code longer. The function code only appears in one place and is called there when used. Ii. execution
