COMP 1020
Exercise #5
There is a problem. We have not checked the diagonals to ensure they add up to the magic constant as well. For example, if we add this square to the text file:
5 23 6 19 2 15 11 24 7 20 3 4 12 25 8 16 17 5 13 21 9 10 18 1 14 22
the program would report it as a magic square, even though it is not. The magic constant is 65 but the sums of the diagonals 23+24+25+21+22=115 and 15+20+25+5+10=75 are both incorrect.
Download the complete magic squares program and add the following features to it:
- Write a method checkDiagonals that sums both diagonals and compares them to the magic constant. Like the other check methods, it should count and print the number of invalid diagonals (or zero if none) and return a boolean value of true on success. Hint: one loop counter can be used to move along both dimensions of the array, so you do not need nested loops.
- Modify the check method to check the diagonals.
Submit your checkDiagonals and check methods (and no other parts of the program) by the due date specified in the course schedule.
