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

Can someone help me of the 3rd challenge on the array-size-and-length on ios?

This is what I typed: float real_numbers[5]; printf("Array real_numbers is %ld bytes.", sizeof(real_numbers)); printf("Array real_numbers can store %ld items.", sizeof(float)/sizeof(real_numbers));

Hi Trent!

You are on the right track, you just need to change your last (third) line. The mistake is in the division, you need to divide sizeof(real_numbers) by sizeof(float), like so:

printf("Array real_numbers can store %ld items.", sizeof(real_numbers)/sizeof(float));

Rodrigo is correct

Thank you Rodrigo :D
