( Another Simple Program )

Given two variables, x and y, create and execute a program that will

(i) ask for input from the user on the values for x and y

(ii) calculate the value of the following algebraic expression z = 5 x ² y ? 2 x y ² + 7 x / y ? x + 2 y ? 17

(iii) display the output of the above mathematical processes; and

(iv) test the program with x = 10 and with y = 5 , and then test the program with two different values of x and y

Some starter code is given below.

SET SERVEROUTPUT ON;

SET VERIFY OFF;

DECLARE

x number := &x_number;

y number

z number

BEGIN

z := 5 * x**2 * y + ;

dbms_output.put_line('The value of the polynomial is ');

dbms_output.put_line( when x = and y = || y );

EXCEPTION -- throw an exception when division by zero

END;
