What is the difference between function and array?
Arrays are always passed-by-pointer to functions, which means that array arguments can pass data into functions, out of functions, or both in and out of functions. Unlike Java, which stores the size or length of the array as an array attribute, C++ requires that we pass the size of the array as an explicit argument.
