Output a void function

I'm programming a word hunting and a problems in the void function is making it difficult. In the code I use functions to scan the array in all directions and returns me the start and end coordinates or exit the function and start reading in another direction, then my doubt is born, it is possible to exit the function, as I indicated with #### #, or do an int function with return 0? Help me with this code and if you notice another error in the code sign me.
