Printf help

float real_numbers[] = { 1, 12, 13, 123, 132}; printf("Array real_numbers is %ld bytes.\n", sizeof(float));

Above is what I am typing in and getting a wrong answer. I need to use the printf function to print the following: "Array real_numbers is x bytes." Any help is greatly appreciated thank you

Hey Ryan,

It wants you to find the size of the real_numbers variable specifically, not just the size of a float variable.

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