Question

Sales Bar Chart
Write a program that asks the user to enter today's sales for 5 stores. The program should then display a bar graph comparing each store's sales. Create each bar in the bar graph by displaying a row of asterisks. Each asterisk should represent $100 worth of sales. Perform input validation that the sales are non-negative values. Make a loop that forces the user to enter valid information to continue the program.

For example, here is a sample run

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

(Each *= 100)

Store 1: **********

Store 2: ************

Store 3: ******************

Store 4: ********

Store 5: *******************

using dev C++; no complicated script please just if statements no arrays

Explanation / Answer

Here is your program. The code is bigger because I have to use multiple statements as you said I should not use arrays. I have added comments for your understanding.

#include <iostream>
using namespace std;

int main(){
   int store1,store2,store3,store4,store5;
  
   cout<<"Enter today's sales for store 1:";
   cin>>store1;
   while(store1 < 0) { // loop to force user to enter non negative number
       cout<<"Enter valid value:";
       cin>>store1;
   }
   cout<<"Enter today's sales for store 2:";
   cin>>store2;
   while(store2 < 0) {
       cout<<"Enter valid value:";
       cin>>store2;
   }
   cout<<"Enter today's sales for store 3:";
   cin>>store3;
   while(store3 < 0) {
       cout<<"Enter valid value:";
       cin>>store3;
   }
   cout<<"Enter today's sales for store 4:";
   cin>>store4;
   while(store4 < 0) {
       cout<<"Enter valid value:";
       cin>>store4;
   }
   cout<<"Enter today's sales for store 5:";
   cin>>store5;
   while(store5 < 0) {
       cout<<"Enter valid value:";
       cin>>store5;
   }

   cout<<"SALES BAR CHART"<<endl;
   cout<<"(Each *= 100)"<<endl;
  
   cout<<"Store 1:";
   for(int i=0;i < store1/100;i++){//loop to print asterisk
       cout<<"*";
   }
   cout<<endl;
  
   cout<<"Store 2:";
   for(int i=0;i < store2/100;i++){
       cout<<"*";
   }
   cout<<endl;
  
   cout<<"Store 3:";
   for(int i=0;i < store3/100;i++){
       cout<<"*";
   }
   cout<<endl;
  
   cout<<"Store 4:";
   for(int i=0;i < store4/100;i++){
       cout<<"*";
   }
   cout<<endl;
  
   cout<<"Store 5:";
   for(int i=0;i < store5/100;i++){
       cout<<"*";
   }
   cout<<endl;
   return 0;
}

Sample Run: -

Enter today's sales for store 1:-2342
Enter valid value:1000
Enter today's sales for store 2:1200
Enter today's sales for store 3:1800
Enter today's sales for store 4:800
Enter today's sales for store 5:1900
SALES BAR CHART
(Each *= 100)
Store 1:**********
Store 2:************
Store 3:******************
Store 4:********
Store 5:*******************
