The program of factorial of a number in pl/sql is given below:
declare -- it gives the final answer after computation fac number :=1; -- given number n -- taking input from user n number := &1; -- start block begin -- start while loop while n > 0 loop -- multiple with n and decrease n's value fac:=n*fac; n:=n-1; end loop; -- end loop -- print result of fac dbms_output.put_line(fac); -- end the begin block end ; |
Output:(if given input as 5)
