使用visual studio完成h264文件的TCP协议传输，给出发送和接收的代码,发送端打印传输的文件的大小，接收端要打印每一帧是否接收正确，还要计算传输时延

以下是发送端的代码示例：

#include <iostream>
#include <fstream>
#include <WinSock2.h>
#include <WS2tcpip.h>

#pragma comment(lib, "ws2_32.lib")

using namespace std;

int main()

    int result = WSAStartup(MAKEWORD(2, 2), &wsaData);
    if (result != 0)
    {
        cout << "WSAStartup failed with error: " << result << endl;
        return 1;
    }

    // 创建套接字
    SOCKET sock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (sock == INVALID_SOCKET)
    {
        cout << "socket failed with error: " << WSAGetLastError() << endl;
        WSACleanup();
        return 1;
    }

    // 设置服务器地址和端口号
    sockaddr_in serverAddr;

    // 连接服务器
    result = connect(sock, (sockaddr*)&serverAddr, sizeof(serverAddr));
    if (result == SOCKET_ERROR)
    {

        closesocket(sock);
        WSACleanup();
        return 1;
    }

    // 打开 H264 文件

    if (!h264File.is_open())
    {

        closesocket(sock);
        WSACleanup();
        return 1;
    }

    // 获取 H264 文件大小
    int fileSize = (int)h264File.tellg();
    cout << "H264 file size: " << fileSize << " bytes." << endl;

    {
        int bytesToRead = min((int)sizeof(buffer), fileSize - bytesSent);
        h264File.read(buffer, bytesToRead);
        result = send(sock, buffer, bytesToRead, 0);
        if (result == SOCKET_ERROR)
        {

            closesocket(sock);
            WSACleanup();
            return 1;
        }

    // 关闭文件和套接字
