控制台启动server时报"对于服务器server-1与计算机machin对于服务器AdminServer, 与计算机Machine-0相关联的节点管理器无法访问。所有所选服务器当前都处于与此操作不兼容的状态, 或未与运行的节点管理器关联, 或没有授权您执行请求的操作。不会执行任何操作次错误基本都遇到过。在网上搜了半天，最后才解决，基本如下：对于服务器server-1与计算机machine-2相关联的节点管理器无法访问。所有所选服务器当前都处于与此操作不兼容的状态, 或未与运行的节点管理器关联, 或没有授权您执行请求的操作。不会执行任何操作。原因：nodemanager没有启起来一、对于managedServer于adminServer在同一服务器上的情况：1、在控制台可查看该机器的节点管理器端口，比如为55562、用netstat -nap | grep 5556命令查看端口为5556的进程是否存在便知nodemanager是否已启动，这时肯定是不存在的3、但是用ps -ef |grep java命令查看进程，可看到NodeManager进程4、用kill -9 NodeManager进程号5、vi /etc/hosts查看ip地址配置是否正确6、vi /etc/sysconfig/network查看机器名配置是否正确7、vi $WL_HOME/common/nodemanager/nodemanager.properties查看以下配置是否正确，这里的端口5556就与上文提到的端口一致，如果端口不对可能是因为在前一次nodemanager起来之后，在控制台修改了端口，而在nodemanager.properties文件中保存的还是原端口，所以当再次启动nodemanager时，启动的端口不是修改后的而是原来的。ListenPort=5556SecureListener=falseStartScriptEnabled=true二、如果AdminServer在服务器A上，ManagedServer在服务器B上的情况：这时候不能启动nodemanager还可能是因为服务器B无法与服务器A通讯，这时候会报socket相关错误。此时，1、在B服务器上修改$WL_HOME/common/nodemanager/nodemanager.properties文件：SecureListener=falseStartScriptEnabled=true2、在B上$WL_HOME/common/bin/目录下执行wlst.sh脚本./wlst.sh即可3、执行完2后会来到wls:/offline>下，在此输入connect()回车4、此时会依次要求输入AdminServer的用户名、密码及url如下Please enter your username [weblogic] :weblogicPlease enter your password [weblogic] :Please enter your server URL [t3://localhost:7001] :t3://adminServerIP:port以上三项指服务器A上登录控制台时的用户名、密码及IP地址和端口5、如果第4步执行成功，则显示Successfully connected to Admin Server "AdminServer" that belongs to domain "my_domain".会跳到wls:/my_domain/serverConfig>my_damain指服务器A上的domain如果第4步执行不成功，会返回第3步重新输入connect()此时也可输入dumpStack()回车，查看具体错误6、第5步执行成功后，在wls:/my_domain/serverConfig>下依次执行nmEnroll("/home/weblogic/Oracle/Middleware/wlserver_10.3/common/nodemanager")nmEnroll("/home/weblogic/Oracle/Middleware/user_projects/domains/server_b_domain")这里的weblogic目录指服务器B上的weblogic目录，视自己的目录修改语句。7、注册成功后，按ctrl+c返回weblogic目录，再到$WL_HOME/servers/bin目录下nohup ./startNodeManager.sh &启动nodemanager如果启动时报以下错误严重: Fatal error in node manager serverjava.net.BindException: Address already in useat java.net.PlainSocketImpl.socketBind(Native Method)at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:365)at java.net.ServerSocket.bind(ServerSocket.java:319)at java.net.ServerSocket.(ServerSocket.java:185)at weblogic.nodemanager.server.Listener.init(Listener.java:54)at weblogic.nodemanager.server.NMServer.start(NMServer.java:205)at weblogic.nodemanager.server.NMServer.main(NMServer.java:355)at weblogic.NodeManager.main(NodeManager.java:31)说明前面以执行过该语句，此时需要杀掉nodemanager的进程号再次执行启动语句。补充：节点管理器类型可选择"普通"。

你上传后的图片展示应该用上传后的网络路径，比如："http://www.yourdamain.com/photo/20100120091326.jpg"，而不是用"E:webjob0231personpersonPhoto20100120091326.jpg"这样的本地路径。因为在网络应用程序对本地图片没有访问权限。 -----------------------------------------------------------当你保存的时候，相当于服务端的内部逻辑，所以用FileUpload1.PostedFile.SaveAs(Server.MapPath("../person/personPhoto/" + filename));是没错的。但当从客户端打开网络应用程序时，调用的路径是相对于客户端的，比如"E:webjob0231personpersonPhoto20100120091326.jpg"，这被认为是客户端的路径，和你直接在浏览器上键入这个地址是一样的效果，打开的是本地文件而不是服务端文件。所以在面向客户端的时候，比如展示图片，必须用网络路径。

对于这个问题，不需要存到数组。按照如下流程即可：1 输入一个字符，对该字符进行判断：a) 如果是数字，则数字累加器加一。b) 如果是字母，则字母累加器加一。c)如果是换行，则结束统计(以换行为结束符。如需其他结束符，根据需要更改判断)。2输出结果。代码：#include <stdio.h>int main(){int c, n, i;c=n=0;while(1){i = getchar();if(i>="0" && i <= "9") n++;else if((i>="a" && i <= "z")||(i>="A" && i <= "Z"))c++;else if(c==" ") break;}printf("数字%d个，字母%d个 ", n,c);return 0;}

struct s {int a,b;} data[2]={10,100,20,200}; 定义了一个数组，data[1]中的a未20b为200然后p=a[1]，把a[1]的值赋给p

#include<stdio.h>int main(){ int date=0,da=0,xiao=0; char c; c=getchar(); while(c!="!") { if(c>="a"&&c<="z") xiao++; if(c>="A"&&c<="Z") da++; if(c>="0" &&c<="9") date++; c=getchar(); // 输入多个字符} printf("xiao=%d,da=%d,date=%d ",xiao,da,date); return 0;}

以下是一个简单的 C 语言程序，可以用于输入十个数，并求出它们的最大值、最小值和平均值：```c#include <stdio.h>int main() { int i; double sum = 0.0, max, min, num; // 输入第一个数，并将其作为最大值和最小值的初始值 printf("请输入第1个数: "); scanf("%lf", &num); max = min = num; sum += num; // 循环输入剩余9个数，并更新最大值、最小值和总和 for (i = 2; i <= 10; i++) { printf("请输入第%d个数: ", i); scanf("%lf", &num); if (num > max) { max = num; } if (num < min) { min = num; } sum += num; } // 输出结果 printf("最大值为: %.2f ", max); printf("最小值为: %.2f ", min); printf("平均值为: %.2f ", sum / 10); return 0;}```在这个程序中，我们使用了一个 `for` 循环来输入十个数，并分别更新最大值、最小值和总和。需要注意的是，我们在循环开始时已经输入了第一个数，并将其作为最大值和最小值的初始值。最后，我们输出计算得到的最大值、最小值和平均值。需要注意的是，在计算平均值时，我们使用了总和除以10的方式来求解，因为本程序中输入了恰好十个数。如果输入的数目不是十个，应该相应地调整计算平均值的方式。

没什么问题啊，除了 第7行 // int ;

//你的错误太多，给你个新的#include<stdio.h>#include<stdlib.h>void da(int a[][4],int n){int i,j,row=0,col=0,max=a[0][0];for(i=0;i<n;i++)for(j=0;j<4;j++){if(a[i][j]>max){max=a[i][j];row=i;col=j;}}printf("最大值：a[%d][%d]=%d ",row,col,max); }int main(){int i,j,n,a[10][4];scanf("%d",&n);for(i=0;i<n;i++)for(j=0;j<4;j++)scanf("%d",&a[i][j]);da(a,n);return 0; }

这是一个仿真实例，可以参考一下，试试。

你的空间没释放！！free(s);free(root);

首先，判断（a++&&b++）这个条件，这个条件中又首先判断a++，得到结果为假（由于是后置自增运算符，所以a在判断的时候为0，判断之后为1）。&&运算中，只要有一个条件为假，则整个条件为假，所以程序不再判断b++这个条件，并且将(a++&&b++)这个条件判定为假。所以程序执行冒号后面的d++。所以a=1,b=0,c=0,d=1。所以答案选D

你好！你选的那个DA芯片？，是做实物还是仿真就行？

input函数中，需要改为char a[10][80];int i;

现在不动手，将来想做这一行，还是要动手，自己动动手吧，也不难。

写一个程序即可。程序详情：#include "stdio.h"main(){int a,b,c;scanf("%d%d%d",&a,&b,&c);if(a>b&&a>c){if(b>c) printf("%d,%d,%d",a,b,c);else printf("%d,%d,%d",a,c,b);}if(b>c&&b>a){if(a>c) printf("%d,%d,%d",b,a,c);else printf("%d,%d,%d",b,c,a);}if(c>a&&c>b){if(a>b) printf("%d,%d,%d",c,a,b);else printf("%d,%d,%d",c,b,a);}getchar();}

已发

#include<stdio.h>void fun2(char a1,char a2,char *a3,int b1,int b2,int *b3,float c1,float c2,float *c3){*a3=a1+a2;*b3=b1+b2;*c3=c1+c2;}void fun1(void){char a1=1,a2=2,a3;int b1=100,b2=300,b3;float c1=5.1,c2=6.8,c3;fun2(a1,a2,&a3,b1,b2,&b3,c1,c2,&c3);printf("a3=%d b3=%d c3=%f ",a3,b3,c3);}int main(){fun1();return 0;}

#include<stdio.h>int main(){char c;int letters=0,space=0,digit=0,other=0;printf("请输入一段字符 ");while((c=getchar())!=" "){if(c>="a"&&c<="z"||c>="A"&&c<="Z")letters++;else if(c==" ")space++;else if(c>="0"&&c<="9")digit++;elseother++;}printf("字母数:%d 空格数:%d 数字数:%d 其他字符数:%d ",letters,space,digit,other);return 0;}如果没有问题请采纳 谢谢

简单的看了下，你代码写的也太不规范了吧？中西结合啊，你以为中西结合代码就很牛B吗？还是全英文吧。Fill方法有11个重载版本的，但是也不是很复杂，因为我们用的时候也就那么一两个。Fill(DataSet）和Fill(dataset ,tablename)。例如Da.Fill(objDataSet)，或者Da.Fill(objDataSet,"Users")。我经常用第二种。你代码中的PasswordTextBox.Text是怎么回事？恕我眼拙！

你这是考试题，还是自己看书吧，书上写的很清楚…

显然是对的嘛!!!
