Missing-Number is a number-placement puzzle. The objective is to fill a 4x4 grid with digits so that each column and each row satisfies an equation such that the given result in the fifth row and column is correct. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution. 911411 44 27 Write a C program that displays the initial board and ask the user to choose the coordinates of a cell to insert or delete a digit. The initial board and the final solutions should be stored in files. Your program implements a function named load board to read from this file. You implement a function to display the board on the screen named drow board. Your program ask the player to input the coordinate of the cell to edit. The as the user if he would like to 1: insert a digit or to 2: remove the current value 3: restart the game to the initial board 4: check: to check the entered values satisfies the equations. The player should not be able to delete a cell filled by . hoard In case of insertion voushould check the inserted value don't Missing-Number is a number-placement puzzle.
