In this exercise, the main code passes to the CheckMatrix function a 2-dimensional array of integer numbers. First, the CheckMatrix function checks if the array represents a square matrix (i.e. number of rows equals number of columns). If the array is not square, the function prints "NONE" and exits. Second, if the array is square, the function checks if it is diagonal or not. A square matrix is diagonal when all elements other than the diagonal elements are zero. For example, the following matrix is a 3x3 diagonal matrix: 300 020 00-4 If the array is diagonal, the function prints 1, otherwise it prints 0. Third, the function checks if the array is scalar or not. A scalar matrix is a diagonal matrix with equivalent diagonal elements For example, the following matrix is a 3x3 scalar matrix: 200 020 002 If the array is scalar, the function prints 1, otherwise it prints 0.
