Using Files—Population Bar Chart
Write a program that produces a bar chart showing the population growth of Prairieville, a small town in the Midwest, at 20-year intervals during the past 100 years. The program should read in the population figures (rounded to the nearest 1,000 people) for 1910, 1930, 1950, 1970, 1990, and 2010 from a file. For each year it should display the date and a bar consisting of one asterisk for each 1,000 people. The data can be found in the People.txt file located in the Chapter 5 programs folder on the book’s companion website.
Here is an example of how the chart might begin:
PRAIRIEVILLE POPULATION GROWTH
(each * represents 1000 people)
| 1910 | ** |
| 1930 | **** |
| 1950 | ***** |
