Tons of || in an if

I don't understand why this does not work. I know that there are better ways to do this program but I'm just concerned about why it didnt work:

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
    
    
    long double pi = 0.0, num = 4.0, denom = 1.0;
    long acc = 10000; 
    int n;
    cout << setiosflags( ios::fixed | ios::showpoint )
    << "count set at: " << acc << "\nterm\t\t pi\n";
 
   for ( long loop = 1; loop <= acc; ++loop ) { 
   
       if ( loop % 2 != 0 )
           pi += num / denom;
       else
           pi -= num / denom;
       
   if (   (loop == 10000) || (loop == 10001) || (loop == 10002) || (loop == 10003)
       || (loop == 10004) || (loop == 10005) || (loop == 10006) || (loop == 10007) || (loop == 10008) 
       || (loop == 10009) || (loop == 10010) || (loop == 10011) || (loop == 10012) || (loop == 10013) 
       || (loop == 10014) || (loop == 10015) || (loop == 10016) || (loop == 10017) || (loop == 10018)
       || (loop == 10019) || (loop == 10020) || (loop == 10021) || (loop == 10022) || (loop == 10023)
       || (loop == 10024) || (loop == 10025) || (loop == 10026) || (loop == 10027) || (loop == 10028)
       || (loop == 10029) || (loop == 10030)  )
       cout << loop << "\t\t" << setprecision( 8 ) << pi << '\n';
           
     denom += 2.0;
 }

 cout << endl;
 
    system("PAUSE");
    return EXIT_SUCCESS;
}

It only prints out the very first loop.

for ( long loop = 1; loop <= acc; ++loop )

What values does loop stop at in this for loop?

Alright, I understand. Dangit.
