关于socket UDP通信：希望大家来纠错

关于socket UDP通信：我想构建一个服务器端给客户端发送一串字符串，第一个是我的服务器端代码，第二个是客户端代码，不知道哪儿有问题发不过去。希望大家帮忙看看

```c
#include 
#include           /* See NOTES */
#include 
  #include 
 #include 
#include

#define POST 5055
#define IP "192.168.232.242"
int main(int argc,char *argv[])
{
    int mysocket=socket(AF_INET,SOCK_DGRAM,0);
    if(mysocket<0)
    {
        printf("获取socket失败\n");
    }
    else
    {
        printf("获取socket成功\n");
    }


    struct sockaddr_in serverinfo;
    serverinfo.sin_family=AF_INET;
    serverinfo.sin_port=htons(POST);
    serverinfo.sin_addr.s_addr=inet_addr(IP);
    
    int ret= bind(mysocket,(struct sockaddr*)&serverinfo,sizeof(struct sockaddr));
    if(ret<0)
    {
        printf("绑定地址失败\n");
    }
    else
    {
        printf("绑定地址成功\n");
    }

    char buff[]="abcdefgaaaaaa";

    struct sockaddr_in clientinfo;

    int len=sizeof(clientinfo);
    int ret1=sendto(mysocket,buff,sizeof(buff),0,(struct sockaddr*)&clientinfo,len);

    return 0;
}

```c

#include 
#include           /* See NOTES */
#include

#include

#define POST 5055
#define IP "192.168.232.242"
int main(int argc,char *argv[])
{
    int mysocket=socket(AF_INET,SOCK_DGRAM,0);
    if(mysocket<0)
    {
        printf("获取socket失败\n");
    }
    else
    {
        printf("获取socket成功\n");
    }


    struct sockaddr_in serverinfo;
    serverinfo.sin_family=AF_INET;
    serverinfo.sin_port=htons(POST);
    serverinfo.sin_addr.s_addr=inet_addr(IP);
    
    int ret= bind(mysocket,(struct sockaddr*)&serverinfo,sizeof(struct sockaddr));
    if(ret<0)
    {
        printf("绑定地址失败\n");
    }
    else
    {
        printf("绑定地址成功\n");
    }
    char buff[64];
    memset(buff,0,sizeof(buff));
    int ret3=recvfrom(mysocket,buff,sizeof(buff),0,NULL,NULL);
    if(ret3<0)
    {
        printf("接收失败\n");
    }
    printf("%s\n",buff);
    return 0;
}

我虽然不懂C语言，但是感觉你的第一段代码中第45行有问题。发送数据报不应该发送给对面的IP和端口吗？为什么是自己绑定的端口mysocket？通常情况下，一般是客户端发送连接，然后服务器根据这个连接的地址来发送数据报
