Courses Plus Student 405 PointsChallenge Task 2 of 3
I keep getting an error on Task 2 of 3 which asks to print the size of the array. It doesn't like my "%ld" and I have no idea what I can do to get the code working. Can anyone tell me what is wrong with my code:
float real_numbers [5]; printf ("Array real_numbers is %lb bytes\n", sizeof(real_numbers));

you used %lb instead of %ld

Try %ld.
Joyce Thomas
Courses Plus Student 405 PointsThank you kindly for your help. One clarification is it an "l" as in "length" and a "d" as in dog? This is what I'm using on my PC but the character looks like a number one "1" when it is written.
Stone Preston
42,016 Pointsyes thats correct. l as in length and d as in dog. %d is for ints, however putting the l in front (%ld) means its for a long int which can store larger numbers (such as sizes in bytes which could be fairly long)

Courses Plus Student 405 PointsThank you Stone and Jason for your help.
I am using the correct format. It is my PC and the homework work space that are at war.
I tried copying both of your "%ld" into the workspace and end up with an error. Completely frustrating!
Jason Anello
Courses Plus Student 94,610 PointsI'm on a pc myself and it is passing fine for me.
I copied Stone Preston 's code and change the 'b' as in boy, to a 'd' as in dog, and it passes.
Stone Preston
42,016 Pointshmm thats strange. just copied in your original answer but changed the format specifier and passed using
float real_numbers [5];
printf ("Array real_numbers is %ld bytes\n", sizeof(real_numbers));
Joyce Thomas
Courses Plus Student 405 PointsMy original code had "b" instead of a "d" and I looked at it 10 times and didn't see it.
Greatly appreciate the help Stone and Jason. I was tearing my hair out and I managed to write the code for three assignments once this was fixed. :)

Courses Plus Student 405 PointsThank you for your help Stone. I used percent, letter "l" as in letter and letter "d" as in dog. %ld. I am using a PC and I think it doesn't like my characters. I copied an pasted your code into the assignment and got the same error.
