console app displaying report at end, need some help
ok so im making this console app in which I have to allow the user to enter any number of values then display orignal value , and then the percentage of the original value to the total. My question is how do I initialize my memory locations correctly for a correct report to display ?
also is my method of asking for more values correct?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class intReport
{
static void Main()
{
//declare memory locations
//
//user provided value
int userInteger = 1;
int userTotal= 1; //totals the value user provides
double percentage = (userInteger / userInteger) * 100;
string userInput; //read user input
bool dataOutput = true;
DisplayInstructions();
while (dataOutput)
{
userInteger = GetInput();
DisplayReport(userInteger, userTotal, percentage);
Console.WriteLine("Would you like to enter additional values?");
userInput = Console.ReadLine();
if (userInput == "y" || userInput == "Y")
{
Console.Clear();
}
else
dataOutput = false;
} // end of while loop
} // end of main
public static void DisplayInstructions()
{
Console.Write("In this program you will be allowed to enter any number of values the program" +
"\n will then total the values and display a report which will show the original"+
"\nentered value as a percentage of the total" +
"\n\n Please press any key to continue.") ;
Console.ReadKey();
Console.Clear();
} //end of display instructions
public static int GetInput()
{
int input;
Console.WriteLine("You will be asked to enter a integer.");
Console.WriteLine(" ");
Console.Write("Please enter a value: ");
int.TryParse(Console.ReadLine(), out input);
Console.Clear();
return input;
} // end of GetInput method
public static double Percentage(int userInteger, int userTotal, double percentage)
{
//int userInteger;
//int userTotal;
//double percentage;
Console.WriteLine("Original Value = {0} ", userInteger);
Console.WriteLine("Org. Value Percentage to the total = {0} ", percentage);
return percentage;
} //end of percentage method
public static void DisplayReport(int userInteger, int userTotal, double percentage)
{
int i;
Console.Write("\n");
Console.WriteLine("Your Results: ");
Console.WriteLine("------------- ");
Console.WriteLine("Original Value: {0}", userInteger);
Console.WriteLine("Percentage: {0}", percentage);
} // emd of display report
} // end of class
} // end of namespaceOn line 16 userTotal should start with being 0, not 1. On line 17 Percentage will always equal 100. Can you use arrays?
Yes i can use arrays just didnt know how to implement them in this case for such a simple problem...guess I should start doing that
Ok so I added a array and added some code to my Percentage method is the correct method ?
using System;
using System.Collections.Generic;

namespace ConsoleApplication1
{
class intReport
{
static void Main()
{
//declare memory locations
//
//user provided value
int userInteger = 0;
int userTotal= 0; //totals the value user provides
//percentage always 100
double percentage = 100;
string userInput; //read user input
double avg;
bool dataOutput = true;
//start array
int[] integers = new int[10];
//sum the values
for (int i = 0; i < integers.Length; i++)
{
userTotal += integers[i];
}
avg = userTotal / integers.Length;
//Console.WriteLine(DisplayReport(integers));
DisplayInstructions();
while (dataOutput)
{
userInteger = GetInput();
DisplayReport(userInteger, userTotal, percentage);
Console.WriteLine("Would you like to enter additional values?");
userInput = Console.ReadLine();
if (userInput == "y" || userInput == "Y")
{
Console.Clear();

} // emd of display report

} // end of namespaceAre you allowed to use LINQ to objects and lists? If so, these have some nice functions built in for summation.
namespace ConsoleApplication1

static void Main()
{

Console.Write("Would you like to enter a value?");
while (char.ToLower(Console.ReadKey(true).KeyChar) == 'y')
{
myInts.Add(GetInput());
Console.Write("Would you like to enter additional values?");
}
if (myInts.Count != 0)
DisplayReport();
else
Console.WriteLine(Environment.NewLine + "Program exitted with no data entered");
Console.ReadLine();
}

Console.Write(Environment.NewLine + "Please enter a value: ");
while (!int.TryParse(Console.ReadLine(), out input))
Console.Write(Environment.NewLine + "Invalid value, enter a new value: ");
Console.Clear();
return input;
}
public static void DisplayReport()
{
int tTotal = myInts.Sum();
double dAvg = (double)tTotal / myInts.Count;
int iCount = 1;
Console.Write("\n");
Console.WriteLine("Your Results: ");
Console.WriteLine("------------- ");
myInts.ForEach(cur => Console.WriteLine("Entry {0} -> Value = {1} , Percent of Total = {2}% ", (iCount++).ToString(), cur.ToString(), (((double)cur / tTotal) * 100).ToString()));
Console.WriteLine("-------------");
Console.WriteLine("Average = {0} ", dAvg);
} }
}
If this is for school and they haven't taught you about either LINQ or Lists<> then I would sugguestnot handing this in. Rather, try learning from it and post any questions you might have.
yes its for school practice. Thanks anyway for providing a solution. My method is I strip down responses like these and understand line by line
