int num_elements = sizeof things / sizeof (short); this is a use of the function "sizeof", in use of this function we can stop of crossing the border of the array.
For a fixed-length array, use std::array, which does not degenerate to a pointer when passed to a function and does know its size. Also, like a built-in array, a stack-allocated std::array keeps its elements on the stack. For a variable-length array, use std::vector, which ...

With a std::array, both the element type and array length are part of the type information of the object. Therefore, when we use a std::array as a function parameter, we have to explicitly specify both the element type and array length: #include <array> #include <iostream> void passBy...
