srand time

When I need to move the entire array element frequently, I first think of the copy Algorithm in memmove and STL, but memmove only applies to strings, the copy algorithm does not overlap des and source. So I wrote one like memmove. #include #include #

# Include # Include # Include Using namespace STD; // Generate a random number (floating point number) in the interval [a, B] or [B, A] Double randdbl (double A, double B) { Return A + static_cast (RAND ()/rand_max * (B-); } // Generate a random

First, explain qsort and sort. They can only sort the data in the continuous memory. structures like linked lists cannot be sorted. First, qsort Qsort, and unstable ). The qsort function integrated in the C language library function uses a three-way

After searching for half a day, I found that the source code of redis looks quite comfortable. So I decided to read the redis source code this year and take a reading Note by the way. Make a good record. Now, the more you don't want to use your head

When constructing various types of data into strings, the powerful features of sprintf seldom disappoint you. Since sprintf and printf have almost the same usage, but the printing destination is different, the former is printed into the string, and

/*************************************** ****************************** This program is a self-replication program. It will copy many programs with different names using its own template,* This replication program also has the ability to replicate

For the location of the smallest element in an array composed of n real numbers, write down The pseudo code of the governance ideology algorithm determines its time efficiency and compares it with the brute force algorithm of the problem. # Include#

In writing a program, you sometimes need to connect two strings. Here we will introduce two functions.Function 1: sprintf Reference: http://oss.lzu.edu.cn/blog/article.php? Tid_877.html Definition:Int sprintf (char * buffer, const char * Format [,

In Linux, the thread read/write lock has a write-first read/write lock, which has the following features: 1) Multiple readers can read at the same time 2) The writer must be mutually exclusive (only one writer is allowed to write, nor can the reader

-----------------------------------------Principle In C language, the pseudo-random number generation algorithm actually uses the "linear same remainder method ". The specific calculation is as follows: I = (Xi-1 * A + C) mod m Where a, c, and m are

The last time I talked about the so-called "non-recursive" fast sorting algorithm, but with the stack to eliminate recursion, it will run longer than the recursive algorithm, we might as well come true. The code is as follows:1#include 2#include

Jump Table (skip list) is a randomized data structure, based on the linked list of parallel, easy to implement, insert, delete, find the complexity of O (Logn). The specific definition of the jump table,The jump watch was invented by William Pugh,
