Need help for Challenge array_length 3of3

Challenge 3of3: 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.

Failed to pass this challenge as my code below. Any pointer?

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

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

Thank you

Hi Wilson,

What kind of error message are you getting?

Did you leave the previous printf statement in place? For task 3 you want to add to the code that you've already written.

It's possible too that it's not liking the \n Try replacing with a period or just taking it out.

sizeof(real_numbers) / sizeof(float) would be the correct way to get the number of items so I think the problem is elsewhere.

Hi Jason, Thank you for the hint! The problem was I didn't leave the printf statement from previous task. ;)
