For my project, I am required to validate the file input based on specific criteria, and then sort and display results. Guidelines below.

The file containing the results of the census is structured as follows:

Field: Age Valid Values: Numeric greater than 0

Field: Gender Valid Values: M, m, F, f

Field: Marital Status Valid Values: M, m, S, s

Field: District Valid Values: Numeric 1 – 22

The fields in each record will be separated by a comma. For example: 21, M, S, 1

The city has 22 districts. The census department wants to see a listing of how many residents are in each district, and a count of residents in each of the following age groups (for all the districts combined): under 18, 18 through 30, 31 through 45, 46 through 64, and 65 or older.

I am currently just looking to get by District Results running correctly. However when I input the following file the results are 10 time more than they should.

File Input:

27, m, f, 4

8, m, f, 2

63, m, f, 4

31, m, f, 3

44, m, f, 3

39, m, f, 4

20, m, f, 1

17, m, f, 1

79, m, f, 1

84, m, f, 4

I think I’ve identified the for loop causing the issue(see comment), but I’m unsure of why or how to fix. Thank you.
