7,837 PointsYou should show your code. You may not in fact be using an array and that might be why it's not working.

16,009 PointsThis should be it:
Challenge 1 of 3:
float real_numbers [5];
Challenge 2 of 3:
float real_numbers [5];
printf ("Array real_numbers is %ld bytes.\n", sizeof(real_numbers));
Challenge 3 of 3:
float real_numbers [5];
printf ("Array real_numbers is %ld bytes.\n", sizeof(real_numbers));
printf("Array real_numbers can store %ld items.\n", sizeof(real_numbers)/sizeof(float));
