Write C++ program to Check if Matrix is Magic Matrix or Not

// CPP program to Check if Matrix is Magic Matrix or Not

//magic matrix is that matrix having sum of all the elements in the row and column as well as diagonal as same values

}

Output:

Matrix A :-->
2  1  6
9  5  1
4  3  8

Given Matrix is Magic Matrix
