      }
      for(q=m-2;q>=0;q--)

           {
                cout<<a[q];
           }

      i++;
 }

}

//Ans is correct.

its hard to read ur code but the questis pretty straignt forward u just need to find the favtorial!

a simple solution would be
ans=1
iterate i from 1 to n
ans*=i
(loop ends)
print ans

cant because the value of 100! has more than 150 digits!!!. You cant use any DataType you have to use an array!!
