Dynamic Typing

Ex:

Use NSLog to print out the value of the variable 'thing'. The output should look like: "thing = 4".

Answer:

id thing = nil;

NSNumber *four = @4;

thing = four;

NSLog(@"thing = %d", thing);

There is a mistake about the output, but i can't find it. i need some help! thanks to everyone :)

Hey Fabrizio,

You simply have an issue with this line NSLog(@"thing = %d", thing);

See if you can find it :).
