Question

CPS 2231: Computer Organization and Programming Programming assignment #1 Concepts: Scanner, loops, input validation, array, methods Point value: 100 points Due date: as noted on blackboard Assignment: Write a program that asks the user to enter today’s sales for five stores. The program should then display a bar chart comparing each store’s sales. Create each bar in the bar chart by displaying a row or asterisks. Each asterisk should represent $100 of sales. You must use a loop to print the bar chart. If the user enters a negative value for the sales amount, the program will keep asking the user to enter the sales amount until a positive amount is entered

Answer 1

Answer:

import java.util.*;

public class BarChart

{

public static void main(String args[])

{

int arr[]=new int[5];

Scanner sc=new Scanner(System.in);

for(int i=0;i<5;i++)

{

while(true){

System.out.println("Enter today's sale for store "+(i+1)+" (negative value not allowed)");

arr[i]=sc.nextInt();  

if(arr[i]>0)

break;

}

}

System.out.println("SALES BAR CHART");

for(int i=0;i<5;i++)

{

System.out.println("Store "+(i+1)+": ");

for(int j=0;j<arr[i];j=j+100)

{  

System.out.print("*");

}

System.out.println("");

}

}

}
