我不懂运营

代码修改与运行结果如下:

#include<stdio.h>

#include<string.h>

char a[10][80];//这个应该是全局变量吧

void input()

{

int i;

for(i=0;i<10;i++)

scanf("%s",a[i]); //这里多了个&

}

void output()

{

int i;

printf("从小到大的顺序为: ");//这句的位置?

for(i=0;i<10;i++)

printf("%s ",a[i]);

}

void sortstring()

{

int i,j;

char t[80];//你这个t的类型什么情况?

for(i=0;i<9;i++)

for(j=0;j<9-i;j++)

if(strcmp(a[j],a[j+1])>0)

{

strcpy(t,a[j]);

strcpy(a[j],a[j+1]);

strcpy(a[j+1],t);

}

output();

}

main()

{

printf("请输入十个字符串: ");

input();//拼写错误

sortstring();

}

这个必须专业人士来解答

小菜G

#include<stdi0.h>

#include<string.h>

struct A

{int a;char b[10];double C;);

void f(struct A t);

main(  )

{struct A a={"1001,"ZhangDa",l098,0};

 f(a);printf("%d,%S,%6.1f",a.a,a.b,a.c);}

void f(struct A t)

{t.a=1002;strcpy(t.b,"ChangRon9");t.c=1202.0;}

程序运行后的输出结果是(  )。

A1001,ZhangDa,1098.0

B1002,ChangRong,1202.0

C1001,ChangRong,1098.0

D1002,ZhangDa,1202.0

tt白

input函数中,需要改为

char a[10][80];

int i;

服务器server0处于不兼容的状态怎么办

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"。

System.UnauthorizedAccessException

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。

c语言输入一串字母 输出字母数字 其它字符的个数

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;}

c语言:输入十个数,求最大值,最小值,平均值

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。

C++实现一个Date类 用日/月/年的格式输出日期,设置日期操作;在Date类基础上,实现一个可以进行加天数操作

#include<iostream.h>static int dys[]={31,28,31,30,31,30,31,31,30,31,30,31};class date{ int yr,mo,da;public: date(int y,int m,int d) { yr=y; mo=m; da=d; } date() {} void disp() { cout<<yr<<"年"<<mo<<"月"<<da<<"日"<<endl; } date operator + (int day) { date dt=*this; day+=dt.da; while (day>dys[dt.mo-1]) { day-=dys[dt.mo-1]; dt.mo++; if (dt.mo==13) { dt.mo==1; dt.yr++; } } dt.da=day; return dt; }};void main(){ int y,m,d,a,b; cout<<"输入年月日:"; cin>>y>>m>>d; date d1(y,m,d),d2,d3; d1.disp(); cout<<"输入要加的天数(整数):"; cin>>a; d2=d1+a; d2.disp();}

在函数中为啥使用结构体指针数组,为其赋值赋不上,(申请了空间),在main函数中可以赋值

你的空间没释放!!free(s);free(root);

123.有以下程序 #include main() { int a=0,b=0,c=0,d=0; (a++ && b++) ? c++ : d++; printf(

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

关于C语言中的while(1)的应用对程序执行的影响

不加while(1)则程序会不停地循环执行整个main()函数,加了的话就会停在while(1)处了。

请VB.net高手帮忙看一下这个错误 Fill 参数太多

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!
