Factorial of 100

Bhaiya in this piece of code when we trying to compute the factorial of 100 this function gives the output as " 0 ".
why did this thing so happen ???

@rajsaxena.personal this is because of range issue of data type you can’t store the result after using long long you have to use array to store your result

@rajsaxena.personal because factorial of 100 is very very big number you cant store it in long long int.
