Compilation Error

My program runs perfectly fine on my pc. But while submitting it on code chef, it shows a long list of compilation errors.
I am a first time submitter... please review my code and help! :)
By the way, I use Turbo C++.

#include <iostream>
using namespace std;

int main()
{
  int t,x,n;
  std::cin>>t;

  while(t--)
  {
    std::cin >> n;
    x=(n/2) + (n/3) + (n/4);
    if (x>n)
      std::cout <<x<<;  // The error is here. Use std::cout <<x<< endl;
    else
      std::cout <<n<<;  // And here as well.
   }
   return 0;
 }

Edited by @anton_lunyov to fix the code display issue and also to indicate errors directly in code.
