Question

A company pays its salespeople on a commission basis. The salespeople each receive $200 per week plus 9 percent of their gross sales for that week. For example, a salesperson who grosses $5000 in sales in a week receives $200 plus 9 percent of$5000, or a total of $650. Write a program (using an array of counters) that determines how many of the salespeople earned salaries in each of the following ranges (assume that each salesperson's salary is truncated to an integer amount): $200-299 $300-399 $400-499 $500-599 $600-699 $700-799 $800-899 $900-999 $1000 and over.

Explanation / Answer

#include<iostream>
#include<cmath>
#include<string>
using namespace std;

//declare variable to hold 9% of their gross
const double percent = 0.09;
const int weekly_pay = 200;
int main()
{
   double gross_earned,total_earning;
   int c,count = 0;
   //declare array of integer for counting number of salesperson in particular range ,size of arraya as 8 because there are 9 ranges
   int range[9] = { 0 };
   //declare array of string for displaying appropriate message for each range
   string range_msg[10] = { "200-299", "300-399", "400-499", "500-599", "600-699", "700-799", "800-899", "900-999", "1000 and over" };
   do
   {
       cout << "Enter the salesperson gross sale: ";
       cin >> gross_earned;
       //calculate total_earning = gross_earned + gross_earned*percent ;
       total_earning = weekly_pay + gross_earned*percent;
       if ((int)total_earning >= 200 && (int)total_earning <= 299)
       {
           ++range[0];
       }
       if ((int)total_earning >= 300 && (int)total_earning <= 399)
       {
           ++range[1];
       }
       if ((int)total_earning >= 400 && (int)total_earning <= 499)
       {
           ++range[2];
       }
       if ((int)total_earning >= 500 && (int)total_earning <= 599)
       {
           ++range[3];
       }
       if ((int)total_earning >= 600 && (int)total_earning <= 699)
       {
           ++range[4];
       }
       if ((int)total_earning >= 700 && (int)total_earning <= 799)
       {
           ++range[5];
       }
       if ((int)total_earning >= 800 && (int)total_earning <= 899)
       {
           ++range[6];
       }
       if ((int)total_earning >= 900 && (int)total_earning <= 999)
       {
           ++range[7];
       }
       if ((int)total_earning >= 1000 )
       {
           ++range[8];
       }
       count++;
       cout << "Want to continue entering gross of salespesron:(y/n?): ";
       fflush(stdin);
       c = getchar();
   } while (c !='n');

   for (int i = 0; i < 9; i++)
   {
       cout << range_msg[i] << ": " << range[i] << endl;
   }

}
