FACTRL2 WRONG ANSWER

#include

{ int a[200];
int n,r=0,q,l,k,g;

}
}

                if((g==0)&&(r==0)&&(flag==0))
                    {
                         m++;
                    }
                if((g==0)&&(r<10)&&(r>0))
                     {
                          m++;
                     }
                g+=r;
                l=g%10;
                a[k]=l;
                r=g/10;
                if(r>0)
                     m++;
           }
      }
      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!!
