does anyone see anything wrong with this code?

local wW = platform.window:width()
local wH = platform.window:height()
local Blink = false
local Clr = 0
local Clg = 0
local Clb = 0
timer.start(.01)

function on.paint (gc)
gc:setColorRGB(0, 0, 0)
gc:fillRect(0, 0, wW, wH)
gc:setColorRGB(Clr, Clg, Clb)
gc:drawRect(0, 0, wW - 1, wH - 1)
end

function on.timer

if Blink == false then
Blink = true
else
Blink = false
end


if Blink == true then
Clr = 0
Clg = 255
Clb = 0
else
Clr = 255
Clg = 0
Clb = 0
end

platform.window:invalidate()
end

write a program that will accept temperatures for the month of September. the program should store the values in an array. the program should calculate and displays the average temperature and also displays the highest and lowest temperature with the their date as recorded

The development team of SoftSols Inc. analyzes the source code of the existing software and notes the following observations: The software contains a private class, named bookTickets, that contains the methods used to perform ticket bookings for various flights. There is no class or function that can be used to check the maintenance details of FlyHigh's aircrafts. Based on the preceding observations, the development team decides to perform the following tasks: Reuse the functions of the bookTickets class in a new class, named bookETicket, to add the feature of e-ticket booking. Create a new class named viewMaintenance that allows the maintenance personnel of FlyHigh Airlines to view the maintenance details of aircrafts. Write the code snippet that the development team should use to accomplish each of the preceding tasks.

PGandE.cpp) Consider a gas and electric bill that
sets two levels of use as follows:
Gas Electric
Baseline Quantities 31 therms 238.7 kwh
Baseline price $.504 /therm $.094 /kwh
Over Baseline Price $.824 /therm $.133 /kwh
Write a program that takes starting and ending
readings for gas and electric meters and calculates
charges to the nearest cent. Use one function to
calculate charges for both gas and electric so as to
eliminate duplicate calculations.
