Question

12. Bar Chart Write a program that asks the user to enter today’s sales for five stores. The program should display a bar chart comparing each store’s sales. Create each bar in the bar chart by displaying a row of asterisks. Each asterisk should represent $100 of sales. Here is an example of the program’s output: Enter today's sales for store 1: 1000 [Enter] Enter today's sales for store 2: 1200 [Enter] Enter today's sales for store 3: 1800 [Enter] Enter today's sales for store 4: 800 [Enter] Enter today's sales for store 5: 1900 [Enter] SALES BAR CHART Store 1: ********** Store 2: ************ Store 3: ****************** Store 4: ******** Store 5: *******************

Answer 1

Hi,

please find the code below.

(since programming language isn't mentioned I have used c++ )

#include <iostream>
#include <stdlib.h> // to use div_t
using namespace std;

int main()
{

   int todaysSales[5];
   int i,j;
   int valOfEachAsterisk=100;
   string a = "*";
  
  
   div_t divresult;
  
   /* initializing elements of array todaysSales */
   for ( i = 1; i<=5; i++ )
   {
      cout << " Enter today's sales for store " << i << ":" << endl;
   cin >> todaysSales[i];
   }

  
  
  
   for (int j = 1; j <= 5; j++)
{
string c;
divresult = div(todaysSales[j],valOfEachAsterisk);
for(int p=1;p<=divresult.quot;p++)
{
  
c+=a;
  
}
cout << "Store" << j << ":"<< c << endl;
}
  
  

   return 0;
}

output:
