Why code is wrong?

float real_numbers[5]; real_numbers[0]=11.11; real_numbers[1]=22.22; real_numbers[2]=33.33; real_numbers[3]=44.44; real_numbers[4]=55.55; printf("Array real_numbers can store %ld items.",sizeof(real_numbers)/sizeof(float));

Why is this cod wrong for showing the length of real_numbers?

Here are the three challenges (one on each line):

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));
