Question

I need a code summary for these problems

Sale Total

Create a Visual C# Windows Console Application that will prompt the user to enter what type of item they are purchasing, the quantity of the item, and the price for the item. Calculate the subtotal, the sales tax and the sales total (subtotal + sales tax) and output all 3 to the user. Assume that the sales tax for your application is 8.5% (create a constant to store this value and use the constant in your calculations).

Student Grade

Create a Visual C# Windows Console Application that will prompt the user to enter their first name, their last name, their student id number as well as their overall percentage grade for quizzes, participations, homeworks, midterm and final exam. Use the percentages from this class to calculate their final grade and output it as a percent.

Answer 1

//Solution 1

using static System.Console;

class SaleTotal
{
public static void Main(string[] args)
{
//constant
const double SALES_TAX = 0.085;//8.5%
string itemName;
int quantity;
double price;
Write("Item name: ");
itemName = ReadLine();
Write("Enter " + itemName + " qunatity: ");
quantity = int.Parse(ReadLine());
Write("Enter " + itemName + "'s price: ");
price = double.Parse(ReadLine());
//calculate subtotal
double subTotal = quantity * price;
double salesTax = SALES_TAX * subTotal;
double salesTotal = subTotal + salesTax;
//print
WriteLine("Sub Total: " + subTotal.ToString("C") + "\nSales Tax: " + salesTax.ToString("C")
+ "\nSales Total: " + salesTotal.ToString("C"));
//pause
ReadLine();
}
}

//output

//Solution 2

using static System.Console;

class SaleTotal
{
public static void Main(string[] args)
{
string firsName, lastName;
int id;
//overall percentage grade
double quizzes, participations, homeworks, midterm, finalexam;
Write("Enter first name: ");
firsName = ReadLine();
Write("Enter last name: ");
lastName = ReadLine();
Write("Enter student id: ");
id = int.Parse(ReadLine());
Write("Enter quizzes percentage: ");
quizzes = double.Parse(ReadLine());
Write("Enter participations percentage: ");
participations = double.Parse(ReadLine());
Write("Enter midterm percentage: ");
midterm = double.Parse(ReadLine());
Write("Enter homeworks percentage: ");
homeworks = double.Parse(ReadLine());
Write("Enter finalexam percentage: ");
finalexam = double.Parse(ReadLine());
double finalGrade = (quizzes + participations + homeworks + midterm + finalexam) / 5;
WriteLine("Final grade: "+ finalGrade.ToString("F")+"%");
//pause
ReadLine();
}
}

//Output
