Output of a void function

Question

I’m programming a word hunt and a problem in the void function is making it difficult. In the code I use functions to scan the matrix in all directions and returns me the initial and final coordinates or leave the function and start reading in another direction, there is my doubt, it is possible to leave the function, as I indicated with #######, or do an int function with Return 0? Help me with this code and if you see another error in the code signal me.

Answer 1

To abandon a function that returns void halfway through, uses return

        if (cacapalavra [i][j] != palavra[k]) return;
