Question

Write a program which will serve as a Magic Square Tester. In particular, your program is to:

1. Read data sets of the following form:

a. N, an integer representing the dimension of the array to be tested (maximum 5)

b. The N*N elements of the array, in row order (first row values, then second row values, etc.)

2. Print the N*N values of the array (matrix) in a two-dimensional format.

3. Print the result of performing the test for both criteria as follows:

a. If both criteria are met, print the message Magic Square! below the matrix values.

b. If either condition is not met (or both are not met), print the message Not a Magic Square! below the matrix and also print the criteria that were not met (Sequence criteria failed. and/or Sum criteria failed.).

4. Test your program on the following data entered into a text file (the first header line is just for informational use only and should not be included in the actual input file):

Any help on how to begin and set up the program correctly would be appreciated.
