Making my first C# program; need help

[Newport]

using System;

using System.Collections.Generic;

using System.Text;

 

namespace Proj2Prep2

{

class Program

{

static double itemName = 0, // entered at keyboard

cameraPrice = 0, // entered at keyboard

cameraDiscount = 0, // cameraPrice * cameraDiscount

cameraAfterDiscount = 0, // camera price after discount

cameraFinalPrice = 0; // cameraTax + cameraAfterDiscount

 

const double cameraTax = .06; // 6 percent camera tax

 

 

 

static void Main(string[] args)

{

 

 

// Ask the user for input

Console.Write("Enter the Item Name: ");

// Convert the input to double and store it in the itemName variable

itemName = Convert.ToDouble(Console.ReadLine());

 

// Ask the user to input their pay per hour

Console.Write("Enter the Price ex.(99.99): ");

// Convert the input to double and store it in the cameraPrice variable

cameraPrice = Convert.ToDouble(Console.ReadLine());

 

 

 

 

 

// calculate the values for grossPay, amtWithheld and netPay

 

calculations();

 

 

// Echo the input and display the calculated values

 

Console.WriteLine("Item:\t\t\t{0}", itemName);

Console.WriteLine("Original Price:\t\t{0:C}", cameraPrice);

Console.WriteLine("Discount:\t\t{0:C}", cameraDiscount);

Console.WriteLine("Price after Discount:\t{0}", cameraDiscount);

Console.WriteLine("Tax:\t{0:c}", cameraTax);

Console.WriteLine("Final Price\t\t\t{0:C}", cameraFinalPrice);

 

Console.ReadLine();

 

 

}//end of Main

static void calculations()

{

 

cameraDiscount = cameraPrice * .15;

cameraTax = cameraAfterDiscount * .06;

cameraFinalPrice = cameraTax + cameraAfterDiscount;

 

}// end of Main

 

static void myOutput()

{

 

Console.WriteLine("Item:\t\t\t{0}", itemName);

Console.WriteLine("Original Price:\t\t{0:C}", cameraPrice);

Console.WriteLine("Discount:\t\t{0:C}", cameraDiscount);

Console.WriteLine("Price after Discount:\t{0}", cameraDiscount);

Console.WriteLine("Tax:\t{0:c}", cameraTax);

Console.WriteLine("Final Price\t\t\t{0:C}", cameraFinalPrice);

 

Console.ReadLine();

 

}

 

}

}

 

 

The part that I bolded and underlined keeps poping up as my only error:

Error 1 The left-hand side of an assignment must be a variable, property or indexer

 

What does this mean? I am completely baffled by this error. It is a variable as stated in my input.... Any ideas?

cameraAfterDiscount - where do you assign a value to this variable? You calculate cameraDiscount but not the after discount value.

 

Also, in this line

Console.WriteLine("Price after Discount:\t{0}", cameraDiscount);

you're using cameraDiscount, it should be cameraAfterDiscount.

[Nemo]

You defined cameraTax as a constant then tried to assign a calculated value to it.

 

 const double cameraTax = .06; // 6 percent camera tax
.
.
.
.
cameraTax = cameraAfterDiscount * .06;

 

That's the source of the error.

I worked through everything and even went to my dad's work. Hes in charge of all of the phones, internet, satellite, everything electronic for the Government of Kansas City, Kansas. He called up 4 of his IT minions and they helped me out. It was awesome. Anyway, here's what the finished program looks like. :thumbs-up:

 

using System;

using System.Collections.Generic;

using System.Text;

 

namespace cameraPrice

{

class Program

{

static string

itemName = "";

static double

cameraPrice = 0, // entered at keyboard

cameraAfterDiscount = 0, // camera price after discount

cameraFinalPrice = 0, // cameraTax + cameraAfterDiscount

cameraTax = 0, // camera tax is 6 percent

cameraDiscount = 0; //camera discount is 15 percent

// end of static varible list

 

static void Main(string[] args)

{

Console.WriteLine("\tProject 2 by Liberty Ruddy Sec 006\n");

 

// Ask the user for input

Console.Write("Enter the Item Name: ");

itemName = Console.ReadLine(); // store item name in itemName variable

 

// Ask the user to input the price for the item

Console.Write("\nEnter the Price ex.(99.99): ");

// Convert the input to double and store it in the cameraPrice variable

cameraPrice = Convert.ToDouble(Console.ReadLine());

 

// Call the calculations and myOutput here

 

calculations();

myOutput();

 

}//end of Main

 

static void calculations()

{

cameraDiscount = cameraPrice * .15;

cameraAfterDiscount = cameraPrice - cameraDiscount;

cameraTax = cameraAfterDiscount * .06;

cameraFinalPrice = cameraTax + cameraAfterDiscount;

 

}// end of Main

 

static void myOutput()

{

Console.WriteLine("\nItem:\t\t\t{0}", itemName);

Console.WriteLine("Original Price:\t\t{0:C}", cameraPrice);

Console.WriteLine("Discount:\t\t{0:C}", cameraDiscount);

Console.WriteLine("Price after Discount:\t{0:C}", cameraAfterDiscount);

Console.WriteLine("Tax:\t\t\t{0:c}", cameraTax);

Console.WriteLine("Final Price\t\t{0:C}", cameraFinalPrice);

Console.ReadLine();

}

 

}

}

 

Thanks for your replies though. :-)

 

The 2 bolded statements were where I was having trouble. At first, i placed "itemName" with all of the variables and assigned it as a double even though the input for that variable would never be a number. So i created its own string. I also screwed up the part where the item cost was to be converted to double. That was fixed and besides a few missing tabs and line spaces, the program worked fine.
