Any suggestions or advices are most welcome !
Try using long long int instead of int.
PS: I don’t know how c++ works but just give it a try 
100!=933262154439441526816992388562667004907159682643816214...nearly a hundred more digits...
These many digits are not supported by any standard c|cpp container. I have done it using trivial multiplication also called super carry method whose implementation is available HERE.
I tried replacing int with long long int as you suggested , but it is still displaying wrong answer . Sorry
