C++. Please fix this code. The code does not use matrices with fixed size at compile time. The code uses a matrix set to n x n, which is not static. Edit the code such that the matrices are fixed at compile time and are static. There should be no changes to the output of this original code and your modified code (for example, when you enter '5' in the original code, you should receive the same result when you enter '5' in your modified code).

/*description: A 7x7 static matrix is created and used to produce an nxn magic matrix.

In a magic matrix, numbers appear only once and sum of the columns, rows, and diagonals are equal.

The user is queried for an odd integer n, where n can be 3, 5, or 7.*/
