Problem In my Code

Problem Code - FCTRL2
here is my code

using namespace std;
#define ll long long

int main()
int t;
cin >> t;
for(int j=0;j<t;j++)

      int i,f=1,n;
      cin >> n;
      cout << f << endl;


can anyone tell what’s the problem with my code

first line of code is just #include you are suppose to add some header to it.
