Objective-C quiz question

Question: Using the printf function print the size in bytes of the variable real_numbers. Your output should look like the following: Array real_numbers is x bytes.

Here's my code of which the print statement is incorrect:

float real_numbers[] = {11.11, 22.22, 33.33, 44.44, 55.55};

printf("float %ld bytes\n", sizeof(real_numbers));

1 Answer

Hi Mark,

Your output is going to be "float x bytes" which doesn't match the expected output of "Array real_numbers is x bytes"

Try changing your output string to match what the challenge is expecting.
