Exercise 4.16 JHTP (Bar Chart Printing Program): One interesting application of computers is to display graphs and bar charts. Write an application that reads 5 numbers between 1 and 30. For each number that reads, your program will display the same number of adjacent asterisks. For example, if your program reads the number 7, it will display *******. Display the bars of asterisk after you read all 5 numbers.
