Newbie syntax issue: error: expected ';' before ')' token

On both for loops (ie: for(len... and for(wid... ), I receive the same error message:

error: expected ';' before ')' token

void
init(void)
{
    //fills board up with numbers
    int tile = (d*d - 1);
    int len = 0;
    int wid = 0;

    for(len < d; len++)
        {
            for(wid < d; wid++)
                {
                    board[len][wid] = tile;
                    tile--;
                }
        }
}

Sorry to ask a similar question as before, but I'm a very confused Newbie!

Every for-loop needs to have its 3 parts (initialization, test, update) and if you don't have one or more of them, you still have to supply the two ;, so

for(len < d; len++)
    ^
    |

should really be

    |
    v
for(;len < d; len++)

and the same for the other for-loop in your function.

For instance, this is how you would set up an infinite loop using for:

for(;;)

where all parts are skipped, but the two semi-colons are still required.

Perhaps this is tutorial/reference on the for-loop is helpful as a review/reference.

In general, a for loop has three parts:

for (initialization; check; update) { ... }

In your code, you are missing the initialization section. You are missing a semi colon in your for loops to denote that you don't need an initialization clause (since you do it above):

void
init(void)
{
//fills board up with numbers
int tile = (d*d - 1);
int len = 0;
int wid = 0;

for(;len < d; len++)
    {
        for(;wid < d; wid++)
            {
                board[len][wid] = tile;
                tile--;
            }
    }

}
