求解整数的最大公约数-the common denominator for Solving Integer

应用背景这是我整理的三次样条插值的算法，算法比较简单，希望大家能用得到，如果，有问题，大家可以好好看一下里面的代码结构，只要仔细看，问题应该都不大的。如果实在不行，就翻翻课本。关键技术 利用FORTRAN编制的三次样条插值，如果三次样条大家都很清楚，我就不用多说了，是行家都懂，如果实在不懂，那就没有下载的必要了。而且程序也相对简单一些。希望能用心好好看。

使用C++实现的Graham扫描法（求解凸包问题），可设置生成随机点的个数、样式，同时支持设置显示范围、显示算法处理时间及使用文件导入导出点等功能。（文件格式为，头四个字节是点的个数，以后分别是各个点的x坐标和y坐标，每个数值均占4字节）。-The use of C++ Realize the Graham scan method (for solving convex hull problems), can be set to generate a random number of points, patterns, and at the same time to support the set display range, display algorithm processing time and the use of document features such as import and export points. (File format for the first four bytes is the number of points, after all points are x coordinates and y coordinates, each account for 4-byte value).

基于AVR的DS18B20函数设计，利用LCD模块显示温度变化，精度高，反应迅速。-AVR-DS18B20 function design based on the use of LCD modules show that the temperature changes, high precision and rapid response.

多层感知器神经网络反向误差传播学习算法多层感知神经网络由输入层、输出层和若干隐层组成本例中用多层感知神经网络求解异或判决问题通过对样本xor.dat的训练进行自学习

java实现质数，短小精干，有解释-few, small and lean, it was explained

糊涂先生给他的五个朋友写信，他写了五封信，但是当他的朋友收到信后，都告诉他：“你的信寄错了”。那么请你计算一下：出现这种情况的概率有多少？（假设糊涂先生是随机地往信封里装信的），你能不能把所有的情况都列出来呢？-confused to his five friends in a letter he wrote five letters, but when his friend received the letter, had told him : "You sent a letter wrong." Then you do some calculations : this happens the probability is the number? (Assuming confused is randomly installed to envelope the letter), you can put all the cases listed?

一些C编程语言经典编程题目，希望对大家有用。#include int main(void) { unsigned int i = 0x12345678; char*pc =(char*)&i; printf("0x%x ", *pc); double *pd = (double*)&i; printf("%f ", *pd); printf("sizeof pc = %d sizeof pd = %d ", sizeof(pc), sizeof(pd)); return 0; }
