Requirements:

Obtain a file name from the user, which will contain data pertaining to a 2D array

Create a file for each of the following:

averages.txt : contains the overall average of the entire array, then the average of each row

reverse.txt : contains the original values but each row is reversed

flipped.txt : contains the original values but is flipped top to bottom (first row is now the last row etc.)

If the dimensions of array are symmetric (NxN), create a diagonal.txt: contains the array mirrored on the diagonal

Example files

The input file will be formatted in the following way:

Sample file called "input.txt"

4 4 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 11.0 12.0 13.0 14.0 15.0 16.0 

Output to averages.txt

Total average: 8.5 Row 1 average: 2.5 Row 2 average: 6.5 Row 3 average: 10.5 Row 4 average: 14.5 

Output to reverse.txt

4.0 3.0 2.0 1.0 8.0 7.0 6.0 5.0 12.0 11.0 10.0 9.0 16.0 15.0 14.0 13.0 

Output to flipped.txt

13.0 14.0 15.0 16.0 9.0 10.0 11.0 12.0 5.0 6.0 7.0 8.0 1.0 2.0 3.0 4.0 

Since it's symmetric we also get diagonal.txt

1.0 5.0 9.0 13.0 2.0 6.0 10.0 14.0 3.0 7.0 11.0 15.0 4.0 8.0 12.0 16.0
