Question

A painting company has determined that for every 115 square feet of wall space, one gallon of paint and eight hours of labor will be required. the company charges $20 per hour for labor. Design a modular program that asks the user to enter the square feet of wall space to be painted and the price of the paint per gallon. The program should display the following data:
The number of gallons of paint required
The hours of labor required
The cost of the paint
The labor charges
The total cost of the paint job

Answer 1

What did you come up with so far?

Answer 2

ahh hey

Answer 3

I didn't think anyone would come lol

Answer 4

anyways, I want to understand the logic of the problem and how it is possible to have

sub modules within the problem

Answer 5

and I would like to understand how to do in psuedocode

Answer 6

any ideas?

Answer 7

Well, first, do you know what it means by modular?

Answer 8

I need to start the problem with a main module and an end module?

Answer 9

I kinda understand how to do the problem with one module, but I am not sure how to break it up into sub modules

Answer 10

Well, it is like a modular closet organizer. See, every closet is similar in that they hold close. Some need more shelves for shoes, other might have a clothes drawer in them, most have a place to hang things. So they sell all of these, and more, as modules and you pick the ones you need.

They applied this idea to programming. Break down a program into small parts that each do a very limited thing. These parts can then be reused as needed.

Answer 11

how bout this, let me tell you what I have so far and see if there is a way we can break into sub modules

Answer 12

Main Module
Declare integer Quantityofpaint
Declare Real Laborhours, Paintcost, Totalpaintcost
Declare Real Laborcharges, Totalcost, Wallspace
Display "Enter the total wall space to be painted in square units: "
Input Wallspace
Set Quantityofpaint = Wallspace
Set Laborhours = 8 * Wallspace
Display "Enter the price of paint per gallon"
Input Paintcost
Set Totalpaintcost = Paintcost * Wallspace
Display "Input the hours of labor: "
Input Laborhours
Set Laborcharges = 20*Laborhours
Set Totalcost = Totalpaintcost + Laborcharges
Display "The number of gallons of paint required is " Quantity of paint
Display "The hours of labor required is " Laborhours
Display "The cost of the paint is " Totaalpaintcost
Display "The labor charges is " Laborcharges
Display "The total cost of the paint job is " Totalcost
End Main module

Answer 13

sorry if that took long to type lol

Answer 14

I have a slight idea of what could be broken into submodules, but I may be wrong. module wallspace, module Paintcost, module Laborhours?

Answer 15

wat is your opinion?

Answer 16

you still there by the way?

Answer 17

Well, I am at work and the only mod on the site at the moment... so I am getting bombarded.

Answer 18

ahh sorry about that, but is there a way I can change the inputs into submodules or no?

Answer 19

B or D Maybe because it seems like to me like that would make more sense hope this helped

Answer 20

B or D?

Answer 21

Yes

Answer 22

wat do you mean?

Answer 23

D i would go with i mean

Answer 24

But this isn't multiple choice

Answer 25

Oh lol sorry about that i'm not really good at this

Answer 26

I have to display all of the five components lol

Answer 27

oh ok lol

Answer 28

I am just rying to figure how I can break the problem into submodules

Answer 29

For this type of problem, you would generally turn the things that do the work into subs. Because there is only one job at a time there is no need to make an instance for each.

Answer 30

for example?

Answer 31

Oh well maybe you can do A B C D with all of your answers you know from the question and some ideas maybe.

Answer 32

A,B,C,D?

Answer 33

And form a paragraph about what you know with each of them

Answer 34

And make a thesis of your answers and how you got them according to what you know

Answer 35

Wallspace()
Display "Enter the total wall space to be painted in square units: "

Answer 36

would that be a submodule?

Answer 37

Hope this helped i usually do this with this type of problem

Answer 38

Yes that would be @luisz

Answer 39

ok let me redo the problem, for I may be gettin the hang of this give me a few minutes

Answer 40

I hope you get it right but you can always check with someone else to see if you are correct or not i would like to see you get this correct

Answer 41

you have anything yet? You catching on? :D

Answer 42

And also draw up a picture too if that helps

Answer 43

Main Module
Declare Integer Quantityofpaint
Declare Real Laborhours, Paintcost, Totalpaintcost
Declare Real Laborcharges, Totalcost, Wallspace
Wallspace()
Display "Enter the total wall space to be painted in square units: "
Set Quantityofpaint = Wallspace
Set Laborhours = 8 * Wallspace
Paintcost()
Display "Enter the price of paint per gallon"
Set Totalpaintcost = Paintcost * Wallspace
Laborhours()
Display "Enter the hours of labor: "
Set Laborcharges= 20 * Laborhours
Set Totalcost = Totalpaintcost + Laborcharges
Display "The number of gallons of paint required is " Quantityofpaint
Display "The cost of the paint is " Totalpaintcost
Display "The labor charges is " Laborcharges
Display "The total cost of the paint job is " Totalcost
End Main Module

Answer 44

am I missing anything?

Answer 45

Yep just label it with A. B. C and D.

Answer 46

by separating parts of your answer

Answer 47

e.mccormick wat is your opinion? Did I answer the problem correctly?

Answer 48

I have no clue what the whole thing about labeling things is about. It has nothing to do with being modular.

The entire focus of modules is making a small piece of code that is reusable and has a clear, specific job.

Answer 49

Oh im sorry I just wanted to help...hope this helped

Answer 50

so did I answer the problem incorrectly or did I answer it in an incorrect fashion?

Answer 51

if you tell me where I want wrong and show me some examples through pseudocode I may be able to understand more efficiently :)

Answer 52

Well, it is hard to say how to make this modular. It inputs two numbers and the rest is math. There are existing input routines, so building them is kind of pointless.

A better example of modular is a card game. Then each card is unique, but related. Each player is also unique but related. The things needed to make one player can be reused to make another, same for making the entire deck.

Answer 53

not sure what that exactly means, but was the problem done correctly in your opinion, or am I missing some things that would make the program run incorrrectly?

Answer 54

Well, it is hrd for me to get time to look at it... like I said, I am getting asked things both on here and at work. In fact, work is sending me somewhere.

Answer 55

http://www.justanswer.com/computer-programming/24oav-6-painting-company-determined-every-115-square.html idk maybe it will tell you

Answer 56

If not i would go @e.mccormick then :/

Answer 57

Your psudocode has one module, the main module.

One thing you could do to make more modules is to emulate a very typical input method. That is one where you pass it a querry message and it returns the user's response.

BEGIN UserQueryIn Method (String Querry)
Display Querry
Return User's Input
END UserQueryIn Method

Then you would do something like this in the main code:

Set Wallspace = UserQueryIn("Enter the total wall space to be painted in square units: ")

That bit of code would use the submodule to output the wall space question to the user and return the result to be assigned to the variable. You then do the same thing for the price of the paint. That is what is meant when you do things in a modular way.
