in c programming language, thanks

declare a data structure to represent a Sudoku puzzle, write some functions to read Sudoku puzzle from a file, - check if a proposed solution follows the Sudoku rules against duplicating values in a row, column, or outlined 3 x 3 square (if needed, we will discuss Sudoku rules in the class) also write a function that can list the possible values for each empty cell according to Sudoku rules. So instead of asking you to write a program that can solve a Sudoku puzzle, you are asked to write a program that can do some of the simple things mentioned above. Specifically, your rogram must do the followings: 1. Declare a minimum size data structure to store the values of a Sudoku puzzle (e.g., 9x9 array of char)
