Pointers and memory...Using the printf function print the size in bytes of the variable real_numbers...

Can not figure this out.

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."

Line 1 is correct, line 2 is not. Answer I have: float real_numbers[] = {1, 2, 3, 4, 5 }; printf("real numbers %ld bytes\n", sizeof(real_numbers));

Hi Derek,

Your only issue is that you're not matching the exact output that it wants.

Output the challenge wants: "Array real_numbers is x bytes."

Your output: "real numbers x bytes\n"
