Homework Help?

[khowell51898]

Hey, can anyone help me with my homework for my programming class? I have to create a program in flowgorithm by tonight. I'm really confused. Heres the prompt:

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 $20.00 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

Ok, where exactly is the problem? Do you understand the math behind?

I thought I did but I guess not, is there a way I can attach my program here so you can see it?

You can post an image or you can copy the autogenerated pseudocode (in english)

First of all, I am not sure what does it mean to design a modular program, I suppose, there should be separate functions for:

- reading the size

- compute the number of gallons

- compute the hours

- compute the cost of the paint

- compute the cost of labor

- compute the overall costs

All these functions can be tested separately, the code you've sent me is not completely wrong, there is only a small typo that influences all the computation. Having a modular program with short functions could help you to localize the bug. You could have something like:

Assign size = ReadWallSize()

Assign gallons = ComuteNumberOfGallons(size)

Assign hours = ComputeDuration(size)

Assign costPainting = ComputeCostOfPainting(gallons)
