Hi, nice to meet you all. Anyways I will get straight to the point, I am having difficulty with a programming assignment it involves loops, I ended up missing the week we were discussing them. Anyways after going back through all my notes and reading my great C# textbook :(. I still have no solution. I have put some work into it but I'm still lost at where to start.

I'll link the assignment at the bottom just first going to show you what I have done!

Here are some constants I assuming I will need

const double MIN = 12.0

const double MAX = 36.0

const double SMALL = 20.0

const double MED = 24.0

const double LRG = 30.0

const int SLICES_SMALL = 8

const int SLICES_MED = 12

const int SLICES_LRG = 16

const int SLICES_XLRG = 24

const int INCREMENT = 4

And some variables

bool continue

double diameter

double pizzaArea

int maxSlices

int slices

double sliceArea

Now I know how to ask for the diameter of the pizza which is simply:

Console.Write("Please enter the diameter of your pizza: ");

            diameterPizza = int.Parse(Console.ReadLine()); 

Up to here is as far as I really know, I'm really bad at programming just need to get through this one course and never take it again. Oh here is the download link: Wikisend: free file sharing service assignment.docx

Edit: Guys i'm trying to learn here so if you do post some code or whatever please explain it to me!

Thanks in advance!

What, exactly, is the program supposed to do? What is the first step? What should it do after that? Do you have a plan?

As for the loops, how much do you know right now? To be honest, I don't know C#, but I do have some experience with programming, so I'll try to do my best with this.

Well if you click my link, thats my assignment on what I am suppose to do. What the first step is to take the input from user. Then next is to run a loop I am assuming that finds out with the diameter given how many slices it will be. Then the area of each slice. As for loops I know pretty much nothing. But if you click my link you can get a better understanding at what i am trying to explain but failing :). Thanks! for responding!

Well, in that case, you'll need to find the area of the pizza. Something like (JavaScript)[noparse]:[/noparse]

var input= prompt ("Enter the diameter:"); // Ask the user for the diameter. 

var diameter= parseFloat (input);  // The input value is a string (text) right now; 

// we have to convert it to a float and save that in the variable 'diameter'. 

var radius= diameter / 2;          // The radius is half the diameter. 

var area_of_pizza= radius * radius * Math.PI; // r^2 * pi = r * r * pi = area of circle 

var slice_count; 

slice_count= /* however many slices there would be... let's just use 8 as an example */ 8; 

var area_per_slice= area_of_pizza / slice_count;        // The area of each slice is the total area over the number of slices. 

// ... 

I don't really have much time to read through the whole document you posted, but above is probably some of what needs to be done.

Note: The code I posted is in JavaScript; that's not too bad, especially because JavaScript is similar to Java, and Java is similar to C# (well, a lot of programming languages are similar to each other).

Well, I'm guessing, from the constants you posted, that you're supposed to check the diameter, and then make the number of slices based on that. So how about this?:

// ... get user input, etc. ... 

var slice_count; 

if (diameter <= 20) slice_count= 8; 

else if (diameter <= 24) slice_count= 12; 

else if ... and so on... I think you get the point. 

else alert ("You entered too big of a diameter; try again, next time, with a smaller value."); 

So that's the determining the number of slices part.

Woaw, don't name variables with names like 'continue' ; even though I don't know C#, I am pretty sure that 'continue' is probably a keyword, as it is in C/C++ and JavaScript and PHP and probably a lot more languages. Some other keywords are 'if', 'else', 'break' (some languages), 'next' (other languages), 'last' (other languages).
