stuck on challenge

I took notes for this lesson specifically so that I wouldn't get stuck on the challenge and here I am, stuck on this challenge. Can someone please tell me what I'm clearly doing wrong here?

your output string is incorrect and you need to print the size of the variable, not the data type. the task states: 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.

so you need to make sure you output string will say " Array real_numbers is x bytes" but replace x with a format specifier, then as the other argument pass in the sizeof the array variable

float real_numbers[5];
printf("Array real_numbers is %ld bytes", sizeof(real_numbers));
