AIM:
To write PL/SQL program using function and procedure..
FACTORIAL OF THE GIVEN NUMBER :
Algorithm for main function:
Accept he value of n in the function FACT two parameters.
Compute the factorial using for loop.
Return the output to main function using return statement.
Stop the program.
Algorithm for main program :
Get the value of n, factorial to be found.
Call the function fact with parameters.
Display the factorial of a given number.
Stop the program.
