It's Magioc A friend tells you about a nifty type of square matrix called a "Magic Square" This friend bets you that you can'tcode up a C+ programthat can determine "Magic Squares" Matrixes A Matrixis a 2 dimensionalarray A squareMatrix has an equal amount of rows and columns An N Matrix is a squarematrix with N rows and N columns (N x N) Magic Square An N Magic Square is a N matrix (i.e... a square N x N matrix) with positive integer values for its elements (values in X's)) An N Magic Square has the following properties 1. 2. 3. It is an N Matrix The integer elements values range from 1 to N squared (N*N) i.e... 1.. N*N The rows, columns and diagonalsall have the same sum, called the Magic Square Sum: Magic Square Sum- [n (n2+1)]/2 4. All the integer elements in the magic squareare unique i.e... no two elements can have the same positiveinteger Example of a 5 Magic Square: 11 24 07 20 03 04 12 25 08 16 17 05 13 21 09 10 18 01 14 22 23 06 19 02 15 Criteria Check: It is a 5x 5 Matrix, so it's a 5 square. The integer elements values range from 1 to (5 x 5) .e... 1.. 25 All the integer element values aredistincti.e... different from each other, no two are equal The rows, columns anddiagonalsall have the same magic sum of 65, so the Magic Sum is 65 All the above criteria aretrue, so it's a 5 magic squarewith a magic sum of 65
