Answer:
long fact(int n)
{
if(n<=1)//base case
return 1;
long p=fact(n-1);//recursive call.
return n*p;//returning the factorial.
}
Explanation:
Above written function is written in C++ language.It is a recursive function to find the factorial of the function.
If we enter a number equal to or less than 1 then the function returns 1. Then the recursive call is made and it is stored in the long variable p and the result is returned as n*p.
