Find the factorial of a number in pl/sql using C++.

In this section, we will see how to find factorial of a number using the PL/SQL. In PL/SQL code, some group of commands is arranged within a block of the related declaration of statements.

Factorial of a number is basically multiplication of all integers from 1 to n, where n is the given number. So n! = n * (n – 1) * (n – 2) * … * 2 * 1.

Example (PL/SQL)

 Live Demo

DECLARE
   fact number :=1;
   n number := &1;
BEGIN
   while n > 0 loop
      fact:=n*fact;
      n:=n-1;
   end loop;
   dbms_output.put_line(fact);
END;

Output

Consider 5 has given
120
