I have a program that calculates the average sales from 3 regions. My problem is that the input is more than half the program, is there a way to reduce the all the input commands?

``````static void Main()
{

while (true)
{
try

System.Console.Write("Enter sales for region1: store 1: "); // asks user to enter Store1, region1 sales.
double a = Convert.ToDouble(Console.ReadLine());// creates double variable a
System.Console.Write("Enter sales for region1: store 2: "); // asks user to enter Store2, region1 sales.
System.Console.Write("Enter sales for region1: store 3: "); // asks user to enter Store3, region1 sales.
System.Console.Write("Enter sales for region1: store 4: "); // asks user to enter Store4, region1 sales.
System.Console.Write("Enter sales for region1: store 5: "); // asks user to enter Store5, region1 sales.
System.Console.Write("Enter sales for region2: store 1: "); // asks user to enter Store1, region2 sales.
System.Console.Write("Enter sales for region2: store 2: "); // asks user to enter Store2, region2 sales.
System.Console.Write("Enter sales for region2: store 3: "); // asks user to enter Store3, region2 sales.
System.Console.Write("Enter sales for region3: store 1: "); // asks user to enter Store1, region3 sales.
System.Console.Write("Enter sales for region3: store 2: "); // asks user to enter Store2, region3 sales.

double[][] region = new double[3][];    // scores
region[0] = new double[5] { a, b, c, d, e }; // input into region0 array
region[1] = new double[3] { f, g, h, };//inout into region1 array
region[2] = new double[2] { l, k }; //input into region3 array
double sum;       // sum of the sales for each region
double total = a + b + c + d + e + f + g + h + l + k; //for calulation of company sales.``````

Thanks for the ideas.

You can use a List<double> to hold your values.
...or two List<double>

You can use a List<double> to hold your values.

I have an array holding the values I believe.

``````double[][] region = new double[3][]; // scores
region[0] = new double[5] { a, b, c, d, e }; // input into region0 array
region[1] = new double[3] { f, g, h, };//inout into region1 array
region[2] = new double[2] { l, k }; //input into region3 array``````

I was wondering if there is anyway, I could loop through and just increase 'a' by one.

``````System.Console.Write("Enter sales for region1: store 2: "); // asks user to enter
double a = Convert.ToDouble(Console.ReadLine());// creates double variable a``````

instead of double a, double b, and so on
Thanks,

Take a look at something like this and add the data directly into the array instead of temporary variables:

``````using System;

namespace DW_412294_CS_CON
{
class Program
{
const int int_NumRegions = 3;
static int[] arr_intStoresInRegions = { 5, 3, 2 };

static double[][] arr_dblRegions = new double[int_NumRegions][];

static void Main(string[] args)
{
for (int i = 0; i < int_NumRegions; i++)
{
arr_dblRegions[i] = new double[arr_intStoresInRegions[i]];
for (int j = 0; j < arr_intStoresInRegions[i]; j++)
{
Console.WriteLine("Enter sales for Region {0}: Store{1}:", i+1, j+1);
// ADD THE DATA DIRECTLY TO THE ARRAY HERE
}
}
}
}
}``````

Hmmm some type of loops might help you, as well as exploring other containers (besides arrays)

``````//Declare the number of stores in each region
int[] Stores_In_Region = new int[] {5, 3, 2};
//This will organize the input data into seperate regions
Dictionary<int, List<double>> InputDataByRegion = new Dictionary<int,List<double>>();

//This temp will hold the input for all the stores in a given region
List<double> tempRegionInput = new List<double>();
//Temp value to use with tryparse to get the decimal value entered
double tempInputDouble = 0;
//Calculates the total regions based on the length of the Stores_In_Region array
int TotalRegions = Stores_In_Region.Length;

//Iterate through every region
for (int i = 0; i < TotalRegions; i++)
{
//Iterate through each store in that region
for (int ii = 0; ii < Stores_In_Region[i]; ii++)
{
//Get the input, validate it with TryParse()
Console.WriteLine(string.Format("Enter sales for region{0}: store{1}: ", i + 1, ii + 1));
Console.WriteLine("Invalid input, enter a new value: ");
//Add this value to the temp input list
}
//Add this list of entries to the current region in the InputByRegion dictionary
InputDataByRegion[i] = new List<double>(tempRegionInput);
//Clear the temp list to get new values
tempRegionInput.Clear();
}

Console.WriteLine("Values by region: ");
//Iterate the dictionary (sorted by region number)
foreach (int RegionIndex in InputDataByRegion.Keys.OrderBy(x => x))
//Iterate the list of values at this region and display it
for (int i = 0; i < InputDataByRegion[RegionIndex].Count; i++)
Console.WriteLine("Region{0} Store{1} = {2}", (RegionIndex + 1).ToString(), i.ToString(), InputDataByRegion[RegionIndex][i].ToString());

Console.WriteLine("Sums by region: ");
//Iterate the dictionary and display the Sum() of each list in it
foreach (int RegionIndex in InputDataByRegion.Keys.OrderBy(x => x))
Console.WriteLine("Region{0} Sum = {1}", (RegionIndex + 1).ToString(), InputDataByRegion[RegionIndex].Sum().ToString());

Console.WriteLine("Sums totals: ");
//using LINQ, this will iterate the dictionary
Console.WriteLine("Total = {0}", (from a in InputDataByRegion select a.Value.Sum()).Sum().ToString());``````

OK. I'm stealing a concept from @skatamatic (an oversight on my part):

``````using System;

namespace DW_412294_CS_CON
{
class Program
{
static int[] arr_intStoresInRegions = { 5, 3, 2 };
static double[][] arr_dblRegions = new double[arr_intStoresInRegions.Length][];
static void Main(string[] args)
{
for (int i = 0; i < arr_intStoresInRegions.Length; i++)
{
arr_dblRegions[i] = new double[arr_intStoresInRegions[i]];
for (int j = 0; j < arr_intStoresInRegions[i]; j++)
{
Console.WriteLine("Enter sales for Region {0}: Store{1}:", i+1, j+1);
// ADD THE DATA DIRECTLY TO THE ARRAY HERE
}
}
}
}
}``````

Thanks, the book actually shows them storing value. I have been done with the assignment, just didn't like the big mess at top.

I understand. I just wouldn't do it that way when it's not necessary.
The book doesn't use loops?

I am guessing we are supposed to use Arrays, as the chapter is on arrays, but will read about other containers.

no it has the nested for loop.
My original code without a way to exit.

``````using System;
using System.Collections.Generic;

public class RegionSales

double a = Convert.ToDouble(Console.ReadLine());// creates double variable a
System.Console.Write("Enter sales for region1: store 2: "); // asks user to enter Store2, region1 sales.
System.Console.Write("Enter sales for region1: store 3: "); // asks user to enter Store3, region1 sales.
System.Console.Write("Enter sales for region1: store 4: "); // asks user to enter Store4, region1 sales.
System.Console.Write("Enter sales for region1: store 5: "); // asks user to enter Store5, region1 sales.

double[][] region = new double[3][];    // scores

double total = a + b + c + d + e + f + g + h + l + k; //for calulation of company sales.     {

for (int i = 0; i < region.Length; i++) // nested for loop // could have uses a foreach as well.
{
sum = 0;
for (int j = 0; j < region[i].Length; j++)
sum += region[i][j];
Console.Write
("The average weekly sales for region {0} is: ", i);
Console.WriteLine((sum / region[i].Length).ToString("F2"));// write the avrage saqles for each region

}
Console.WriteLine("total of all stores: {0}", (total).ToString("F2"));// used to show to total amount made for the company.
