Print the length of the array real_numbers using the sizeof() function. Your output should look like the following: Arra

I got this for this question printf("Array real_number can store %ld items", size of(real_numbers));

would it this be correct? or something wrong in my code?

you are close. what you currently have prints the size in bytes of the entire array.

you need to print the number of items in the array, not the size in bytes. since we know the array is storing float types, dividing the size of the array by the size of a float gives you the number of items in the array

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

in your code above you also mispelled sizeof as size of and left the s of of real_numbers
