Answer:
Seasons Write a program that takes a date as input and outputs the date's season. The input is a string to represent the month and an int to represent the day. Ex: If the input is: April 11 the output is: Spring In addition, check if the string and int are valid (an actual month and day). Ex: If the input is: Blue 65 the output is: Invalid Invalid The dates for each season are: Spring: March 20 - June 20 Summer: June 21 - September 21 Autumn: September 22 - December 20 Winter: December 21 - March 19 LAB ACTIVITY 3.24.1: LAB: Seasons 0/10 main.cpp Load default template... 1 #include eam> 2 #include <string> 3 using namespace std; 4 5 int main() 6 string inputMonth; 7 int inputDay; 8 9 cin >> inputMonth; 10 cin >> inputDay; 11 12 /* Type your code here. */ 13 14 return; 15 }
Answer:
The procedure in SQL is created as follows
Explanation:
--creating the procedure
CREATE OR REPLACE PROCEDURE prc_inv_amounts (W_IN IN NUMBER)
AS
--defining variables
W_CK NUMBER := 0;
W_SUBT NUMBER := 0;
W_TAX NUMBER := 0;
BEGIN
--Authentication process of the invoice
SELECT COUNT(*) INTO W_CK FROM INVOICE WHERE INV_NUMBER := W_IN;
--Transaction confirmation
IF W_CK = 1 THEN
SELECT SUM(LINE_TOTAL) INTO W_SUBT FROM LINE
WHERE
--checking the invoice for the desired invoice number
LINE.INV_NUMBER = W_IN;
W_TAX :=W_SUBT * 0.08;
--updating the invoice
UPDATE INVOICE
--setting the new values
SET INV_SUBTOTAL = W_SUBT,
INV_TAX = W_TAX,
INV_TOTAL =W_SUBT + W_TAX
WHERE INV_NUMBER = W_IN;
--ending the if statement
END IF;
--ending the procedure
END;
Add the following constants in the class definition, before the main method:
private final static float START_COST = 1.5f;
private final static float HIGH_TARIFF = 0.5f;
private final static float LOW_TARIFF = 0.25f;
private final static int FIXED_MINS = 2;
private final static int HIGH_TARIFF_MINS = 10;
Then add this to the main method you already had:
float price = START_COST;
if (x > FIXED_MINS) {
if (x <= HIGH_TARIFF_MINS) {
price += HIGH_TARIFF*(x-FIXED_MINS);
}
else {
price += HIGH_TARIFF*(HIGH_TARIFF_MINS-FIXED_MINS)
+ LOW_TARIFF*(x-HIGH_TARIFF_MINS);
}
}
System.out.printf("A %d minute call costs %.2f", x, price);
