vs2022下 socket编程，main 已经在 server.obj 中定义 错误

vs2022下学习C++ socket编程

//server.cpp
#include <stdio.h>  
#include <winsock2.h>  
#pragma comment(lib,"ws2_32.lib")  
int main(int argc, char* argv[])
{
    //初始化WSA  
    WORD sockVersion = MAKEWORD(2, 2);
    WSADATA wsaData;
    if (WSAStartup(sockVersion, &wsaData) != 0)
    {
        return 0;
    }
    //创建套接字  
    SOCKET slisten = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (slisten == INVALID_SOCKET)
    {
        printf("socket error !");
        return 0;
    }
    //绑定IP和端口  
    sockaddr_in sin;
    sin.sin_family = AF_INET;
    sin.sin_port = htons(8888);
    sin.sin_addr.S_un.S_addr = INADDR_ANY;
    if (bind(slisten, (LPSOCKADDR)&sin, sizeof(sin)) == SOCKET_ERROR)
    {
        printf("bind error !");
    }
    //开始监听  
    if (listen(slisten, 5) == SOCKET_ERROR)
    {
        printf("listen error !");
        return 0;
    }
    //循环接收数据  
    SOCKET sClient;
    sockaddr_in remoteAddr;
    int nAddrlen = sizeof(remoteAddr);
    char revData[255];
    while (true)
    {
        printf("等待连接...\n");
        sClient = accept(slisten, (SOCKADDR*)&remoteAddr, &nAddrlen);
        if (sClient == INVALID_SOCKET)
        {
            printf("accept error !");
            continue;
        }
        printf("接受到一个连接：%s \r\n", inet_ntoa(remoteAddr.sin_addr));

        //接收数据  
        int ret = recv(sClient, revData, 255, 0);
        if (ret > 0)
        {
            revData[ret] = 0x00;
            printf(revData);
        }
        //发送数据  
        const char* sendData = "你好，TCP客户端！\n";
        send(sClient, sendData, strlen(sendData), 0);
        closesocket(sClient);
    }
    closesocket(slisten);
    WSACleanup();
    return 0;
}

运行结果及报错内容

错误    LNK2005    main 已经在 server.obj 中定义    client.obj
错误    LNK1169    找到一个或多个多重定义的符号        T1.exe

请求，能让我把程序跑起来，socket编程初学者真不懂

你多个cpp文件里有main函数？
