Create an NSMutableDictionary called 'carDict'. Allocate memory and initialize 'carDict' with the following key/value pairs: "Make":"Honda", "Model":"Accord". Do this all in one line of code.
my answer:
NSMutableDictionary *carDict = [[NSMutableDictionary alloc] carDict initWithObjectsAndKeys: @"Make", @"Honda", @"Model", @"Accord", nill];
doesnt anyone could tell me where I made a mistakes???
NSMutableDictionary *carDict = [[NSMutableDictionary alloc] carDict :initWithObjectsAndKeys: @"Make", @"Honda", @"Model", @"Accord", nill];

NSMutableDictionary *carDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys: @"Make", @"Honda", @"Model", @"Accord", nill];
