Lab 11 - Is This Box a Magic Box?
Objectives:
Define a two dimensional array
Understand how to traverse a two dimensional array
Code and run a program that processes a two dimensional array
Instructions:
A magic square is a matrix (two dimensional arrays) in which the sum of each row, sum of each column, sum of the main diagonal, and sum of the reverse diagonal are all the same value.
You are to code a program to determine if a given two-dimensional array (that will be read in from a file) is a magic square or not. The functions you will need to code are as follows:
Code a function/method for each of the following:
Read data into the matrix
Print the matrix on the screen
Sum a row given the index for that row
Sum a column given the index for that column
Sum the main diagonal
Sum the reverse diagonal
Determine if the two dimensional array is a magic square
The main method will read the size of the array outside of the while loop.
Then inside the while loop it will call all the methods given above to read the data into the matrix, print the matrix, print all the row sums, print all the column sums, and print both diagonals.
Then the program will determine if the matrix is a magic square and print an appropriate message. The next size should be read in at the end of the while loop.
The main will continue with the next matrix in the data file, until a size of -1 is reached. See the Additional Notes on Two Dimension Arrays for more help with this assignment.
Sample Output:
The first part of the output should look similar to this:
=========
= Square 1=
=========
8 1 6
3 5 7
4 9 2
The sum of row 0 is 15
The sum of row 1 is 15
The sum of row 2 is 15
The sum of column 0 is 15
The sum of column 1 is 15
The sum of column 2 is 15
The main diagonal is 15
The other diagonal is 15
This matrix is a magic box!
