Appropriate data type selection

#1

What data type should be used to save the answer for calculating 100! ??? I tried using long long int but it wasn’t able to pass all the test cases.

#2

@jha.aparna17 there is no datatype big enough in c++ to store such a large value. You will have to store the digits individually in an array.

#3

But when i used long double and provided custom input, i got the right answer

#4

@jha.aparna17 but it cannot store a number as big as 100!
