[M-12]Write a main() program that
prints an n by n square of characters. Make the square out of bands that are
4 characters wide. Use four different characters for the bands, and keep repeating
the bands until the square is finished. Here is the output when n==24:
************************ ************************ ************************ ************************ ........................ ........................ ........................ ........................ oooooooooooooooooooooooo oooooooooooooooooooooooo oooooooooooooooooooooooo oooooooooooooooooooooooo ++++++++++++++++++++++++ ++++++++++++++++++++++++ ++++++++++++++++++++++++ ++++++++++++++++++++++++ ************************ ************************ ************************ ************************ ........................ ........................ ........................ ........................
If n is not a multiple of four, the last band will have fewer than four rows.
