IOS - Stage 3 Pointers and Memory - code: Array Length

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.

my input is this:

float real_numbers[5]; printf("Array real_numbers is %ld bytes.\n", sizeof(real_numbers)); printf("Array real_numbers can store %ld times\n", sizeof(real_numbers)/ sizeof(float));

the line I am having trouble with is:

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

the error code displays:

That was not the correct string. Do you have the correct format character? sizeof(real_numbers) returns a long. That format character is '%ld'.

I would appreciate if someone could tell be what I am missing in this code, I would of thought that you would have to divide the total number of bytes in the array by the number of bytes in a float as that was what was shown on the video tutorial.

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

you have times, not items. it should be

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

thanks, I can't believe I didn't see that! haha

no worries
