Reporting on Monthly Sales
I have been tasked with the following:
I am new to programming. I need to create a program that tracks sales. The store owner wants to keep track of monthly sales.
Ask the user for the monthly income of the store (one question per month) keep the numbers input 0-50. Store all the info in an array.
Calculate the statistics (average, standard deviation, minimum sales and maximum sales for the year.
Output to the screen a text based graph that shows monthly sales for the year.
Sample graph:
*
* *
* * *
* * *
Jan (4) Feb(2) Mar (3)
(the astricks should be above the month in the graph...for some reason it's not showing that way here)
This is what I have done so far. I am getting undeclared identifier errors and a few "{" errors. Can someone help get me in the right direction?
