iOS Objective-C Basics (Retired) Pointers and Memory Array Size and Length

Array Length Quiz help

Im a little confused here. Either I'm missing the Objective-C part in the Video or they just aren't there. Like in the previous video %s wasn't even explained? Anyways, here is what I have so far:

float real_numbers[5] = {1.1, 2.2, 3.3, 4.4, 5.5}; printf("Array real_numbers is %ld bytes\n", sizeof(real_numbers)); printf("real_numbers can store %ld items.\n", sizeof(real_numbers)/sizeof(float));

Hi Jeffrey,

Your output for the last one doesn't match the format of what the challenge requested.

Output should be "Array real_numbers can store x items." You're missing "Array " at the beginning.

Also, this is fine for task 1: float real_numbers[5];

You don't have to initialize the array with values. You simple need to declare space for 5 floats.

Over thinking and missing details! Thanks for answering that despite the obvious!
