When we define an array, as in

int x[3];

the name x refers to a set of unnamed int elements that are contiguously stored in memory. We make references to each of these three unnamed int elements using the subscript or index or array operator []

C/C++ arrays are always "-origin". That is, the definition int x[3] defines the elements x[0], x[1], and x[2].

Given the following declaration statement:

float x[] = {1.1f, 2.2f, 3.3f};

write the exact value resulting from the evaluation of expression sizeof(x[1]).
