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

Challenge 3 of 3

For the 3 challenge Challenge task 3 of 3 Print the length of the array real_numbers using the sizeof() function. Your output should look like the following: Array real_numbers can store x items.

I am executing the below code and I am getting an error in executing it. Please help and tell me what is wrong in the code

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

You are not asked to specify the contents of the float array. You just need to write:

float real_numbers [5];

You are also missing the second challenge, which is:

printf ("Array real_numbers is %ld bytes.\n", sizeof(real_numbers));

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

The problem was with specifying the contents of float array. Thanks
