Run configuration'Tomcat' is runing.

This message means that a Tomcat server is already running in your development environment. You can either stop the running server or change the port number for the new server that you want to run. To stop the running server, you can go to the Tomcat console and click on the "Stop" button. If you want to change the port number, you can do so in the server configuration file and then restart the server.

修改下列代码中的错误： #include <iostream> using namespace std; int main () {int n; cin<<n<<endl;; if(n==1){cout<<"hero is idleling..."<<endl; cout<<"hero is attack..."<<endl; cout<<"hero is runing..."<<endl; cout<<"hero is dead..."<<endl;} else{cout<<"Monster is idleling..."<<endl; cout<<"Monster is attack..."<<endl; cout<<"Monster is runing..."<<endl; cout<<"Monster is dead..."<<endl;} }

代码中的错误有：

1. `cin` 语句中应该使用 `>>` 而不是 `<<`。

2. 第三行代码中多了一个分号 `;`。

3. `if` 语句中缺少左大括号 `{`。

4. `else` 语句中缺少左大括号 `{`。

下面是修改后的代码：

#include <iostream> 
using namespace std;  

int main () {
    int n;  
    cin >> n;  

    if(n == 1) {
        cout << "hero is idleling..." << endl;  
        cout << "hero is attack..." << endl;  
        cout << "hero is runing..." << endl;  
        cout << "hero is dead..." << endl;  
    } 
    else {
        cout << "Monster is idleling..." << endl;  
        cout << "Monster is attack..." << endl;  
        cout << "Monster is runing..." << endl;  
        cout << "Monster is dead..." << endl;  
    }    
}

centos7.9 系统error cannot connect to the docker daemon at unix:///var/run/docekr.sork. is the docker daemon runing

在CentOS 7.9系统中，出现"cannot connect to the docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"错误通常是由于Docker守护进程未启动引起的。你可以按照以下步骤来解决这个问题：

1. 检查Docker守护进程的状态：

systemctl status docker

如果守护进程未运行，你可以使用以下命令启动它：

sudo systemctl start docker

2. 如果守护进程已经在运行，但仍然出现错误，请尝试重启Docker服务：

sudo systemctl restart docker

3. 如果问题仍然存在，你可以尝试重启主机来解决问题。
