注意:不要再return 的语句之后加,那样就执行不到了. system() 是调用系统命令:pause 暂停命令: 如果加有  system(”pause“): 这样在运行到此处时,会显示“Press any key to continue . . .” 也就是 “按任意键继续...”: 在VC 6.0下,要添加如下的头文件! #include <stdlib.h>   在c++  程序中用#include<iostream>也可以…

C语言有一个system函数(在<stdlib.h>头中,C++则为<cstdlib>头),可以用来调用终端命令.原型如下: int system(const char *cmdline /* 命令字符串 */); system函数调用/bin/sh  执行特定的shell命令,阻塞当前的进程知道shell命令执行完毕.执行system实际上是调用了fork函数(产生新进程).exec函数(在新进程中执行新任务).waitpid函数(等待新进程结束).   函数详解 在 Linux…

一.粒子系统简介: 粒子系统最早出现在80年代,主要用于解决由大量按一定规则运动(变化)的微小物质在计算机上的生成和显示问题.Particle System的应用非常广泛,大的可以模拟原子弹爆炸,星云变化,小的可以模拟水波.火焰.烟火.云雾等,而这些自然现象用常规的图形算法是很难逼真再现的. Particle System可以说是一种基于物理模型来解决问题的方法,它的核心不在于如何显示,而在用于对微小物质模型的规则提取. 粒子运动(变化)的规则可以很简单也可以很复杂,这取决你所模拟的对象.举例来…

个人心得:百度推荐的简单DP题,自己做了下发现真得水,看了题解发现他们的思维真得比我好太多太多, 这是一段漫长的锻炼路呀. 关于这道题,我最开始用DP的思路,找子状态,发现自己根本就不会找DP状态数组建立,怎么找都是被后面的给打乱了, 看到了网上的DP[i][j],i表示前几个设备,宽带为j的最少花费,哇,真得厉害,突然发现动态规划并不需要做到问题很完美, 其实只要解决方案能够顺带把这个解决就好了. 他的这个转移方程就是,当i等于1时,输入的想,输入的x,y(x表示宽带长度,y表示价格)dp[i…
