Anyone knows how to send packets to a server in c++?

I tried this code snipper i found somewhere, but it doesnt seem to work.
Code:

#include <cstdlib>
#include <iostream>
#include <windows.h>

char FakePlayer[] = {0x02, 0x00, 0xFC, 0x01, 0x07, 0x4B, 0x61, 0x64, 0x64, 0x61, 0x6B, 0x61, 0x00, 0x09, 0xC8, 0x96};
bool bPower = false;

   
sockaddr_in RecvAddr;
int main(int argc, char *argv[])
{
   int port = 36964;
   SOCKET sendSocket;
   WSADATA wsaData;   
   WSAStartup(MAKEWORD(2,2), &wsaData);
   RecvAddr.sin_family = AF_INET;
   RecvAddr.sin_port = htons(port);
   RecvAddr.sin_addr.s_addr = inet_addr("91.121.13.214");
   while(true)
   {
      if(bPower)
   sendto(sendSocket, FakePlayer, strlen(FakePlayer), NULL, (SOCKADDR*)&RecvAddr, sizeof(RecvAddr));
      if(GetAsyncKeyState(VK_F2) && !bPower)
         bPower = true;
      if(GetAsyncKeyState(VK_F2) && bPower)
         bPower = false;

      Sleep(5000);
   }
   return 0;
}



these are my compiling errors:
1>main.obj : error LNK2019: unresolved external symbol _sendto@24 referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol _inet_addr@4 referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol _htons@4 referenced in function _main
1>main.obj : error LNK2019: unresolved external symbol _WSAStartup@8 referenced in function _main

Link it with WS2_32.lib.

I would suggest you do not copy codes, and learn the subject yourself.
