Objective-C Implementing a class (Initialization of array) -

my initialization of array getting weird error. i'm missing? error @ gameboard array.

@implementation tictactoe - (id)init { self = [super init]; if (self) { gameboard [3][3] = {{0, 0, 0}, {0, 0, 0}, {0, 0, 0}}; // error saying: "expected expression" turn = 1; winner = 0; cellschosen = 0; } ...

you have gameboard declared in @interface tictactoe, right? cannot utilize c array initialization syntax, because array initialized. unfortunately c doesn't provide shortcut assign arrays, should create temporary array initialized values , utilize memcpy re-create elements array.

... if (self) { int tmpgameboard[3][3] = {{0, 0, 0}, {0, 0, 0}, {0, 0, 0}}; nsassert(sizeof(tmpgameboard) == sizeof(gameboard), @"gameboard not 3x3 array"); memcpy(gameboard, tmpgameboard, sizeof(tmpgameboard)); ...

nsassert used create sure haven't changed array size in interface , forgot update initialization (it improve utilize compile time assertion instead of nsassert, that's topic).

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
