In C++!

A real program would also need/want some other functions (checking diagonal fit, placing words vertically, etc...). We are just are focusing on an interesting subset of likely functions. void printKey(const char grid[ROWS][COLS]) Print out the current puzzle grid in a format like that shown below: A 1 E 1 RO GR AM D 12 void printPuzzle(const char grid[ROWS][COLS]) Print out the current puzzle grid, but where there are empty spaces, print random characters. This should NOT actually modify the puzzle grid - the random characters are just shown in the output.

To'fit' a word needs to not extend past the last column AND all the letters in the word need to not conflict with existing words in the grid. This should NOT actually change the grid. Example: given this starting grid
