第一个PHP文件，MySQLPDO.phpphp/连接数据库，并且建立持久化的PDO连接以及捕捉错误异常/functionMySQLPDO($dbnameis,$usernameis,$passwordis)//数据库类型$type'mysql';//数据库名$dbname$dbnameis;//

include<stdio.hinclude<stdlib.hinclude<conio.hinclude<string.hinclude<windows.hinclude<malloc.hinclude<dos.hdefinelensizeof(structdorminfo)

sockaddr\_in与sockaddrsockaddr是在头文件/usr/include/bits/socket.h中定义的，如下：/Structuredescribingagenericsocketaddress./structsockaddr

　　首先php中有常用的两种方法将文件包含：include和require，而include\_once和require\_once无非就是升级版而已，这里就不阐述他们的区别，我只提一下我遇到的问题：　　先看一下有这么几个文件，文件的层级结构如下：Demo/dir1a.phpd

该方法作为一种演示功能左右，运行较慢。include<iostreamusingnamespacestd;classFibonacci{public:inta,b,c;voidgenerate(int);};vo

 include<iostreamusingnamespacestd;introad105105,dis105,n;boolIn105;intDijkstra(intstart,intend);intmain(){intm,a,b,c

服务器错误信息来自下述源文件：·错误消息信息列在share/errmsg.txt文件中。“%d”和“%s”分别代表编号和字符串，显示时，它们将被消息值取代。·错误值列在share/errmsg.txt文件中，用于生成include/mysqld\_error.h和include/mysqld\_ername.hMySQL源文件中

题目：以下代码结果是多少？\include<iostreamusingnamespacestd;int func(int x){int count\0;while(x){count;x\x&(x\1);
