C error “variable-sized object may not be initialized” [duplicate]

Your two arrays are variable lenght arrays. You cannot initialize a variable length array in C.

To set all the int elements of your arrays to 0 you can use the memset function:

memset(plansza, 0, sizeof plansza);

By the way to initialize an array which is not a variable length array, the valid form to initialize all the elements to 0 is:

int array[31][14] = {{0}};  // you need the {}
