Printing Array length challenge. stuck...

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.

float real_numbers [5] = {};

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

It wanted me to give the array a length of 5 and now it wants me to print the top statement and i am doing something wrong! appreciate some help.

you need to be sure you dont delete code from previous tasks. Your code works, you just need to put the code from task 2 back in

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));
