Why is this wrong?

float real_numbers[5];

printf("Array real_numbers is %ld bytes.\n", sizeof(real_numbers)/sizeof(float) );

Welcome to Treehouse, Simon Friend !

It look's fine but the text has to be "Array real_numbers can store...", so the complete solution for Challenge task 3 of 3 of "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." should look like:

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