Sales Array

Use a one-dimensional array to solve the following (or you could just use 10 integer variables) .

A company stores the sales that sales people achieved in a comma delimited sequential file in the format: SalesPersonID, SaleAmount

E001,44

E002,22

E003,45

E004,89

E005,56

E006,55

For example salesperson with the ID E001 sold 44 units

Write a program that determines how many salespeople had sales in each of the following ranges.

0-9, 10-19,20-29,30-39,40-49,50-59, 60-69,70-79,80-89,90-100

Display the results as a bar chart which displays a "#" representing the number of results in each range . Your program will have a least two methods besides the Main Method, one to determine the grade range and another to print the bar chart.

Example Output :

Sale Distribution

0-9

10-19

20-29 #

30-39

40-49 ##

50-59 ##

60-69

70-79

80-89 #

90-100

Try this:

using System;

using System.IO;

class Program

{

static void Main()

{

int[] sales = new int[10];

string[] lines = File.ReadAllLines("sales.csv");

foreach(string line in lines)

{

string[] items = line.Split(',');

int sale = int.Parse(items[1]);

int grade = GetGradeRange(sale);

sales[grade]++;

}

PrintBarChart(sales);

Console.ReadKey();

}

static int GetGradeRange(int sale)

{

if (sale == 100) sale = 99;

return sale/10;

}

static void PrintBarChart(int[] sales)

{

Console.WriteLine(" Sales Distribution\n");

for(int i = 0; i < 10; i++)

{

int start = i * 10;

int end = start + 9;

string hashes = new string('#', sales[i]);

if (end == 99) end = 100;

Console.WriteLine("{0,2} - {1,3} {2}", start, end, hashes);

}
