Question

I have 2 2D arrays that represent a maze

const char maze1[10][11]
and
const char maze2[20][21]

I’m trying to create 1 function to handle both mazes like so:

void solveMaze(maze[][])
{
}

and just pass the maze like solveMaze(maze1);

How would I do this with function templates?

I recently asked this question already but explicitly asked not to use function templates because I wasn’t sure on how to use it, but I would like to see how it would work. (hope this isn’t “abusing” the system)

Answer 1

There is no real support for multidimensional Arrays. You should consider using a class with proper support for the dimensions. The following does the trick

template<int N, int M>
void solveMaze(const char (&maze)[N][M]) {
    size_t n = N;
    size_t m = M;
    int x = 0;
}

int main(int argc, char *argv[])
{
    const char maze[3][2] = { { 0, 1} , {2, 3}, {4, 5} };
    solveMaze(maze);
    return 0;
}
