An array as a function argument. 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. Passing data by pointer involves two variables: the original data and a pointer.
How do you define an array in a function?
To pass an entire array to a function, only the name of the array is passed as an argument. result = calculateSum(num); However, notice the use of [] in the function definition. This informs the compiler that you are passing a one-dimensional array to the function.

How does an array work?
An array is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation, its length is fixed. Each item in an array is called an element, and each element is accessed by its numerical index.
How an array is passed to the called function?
Passing array to function using call by reference When we pass the address of an array while calling a function then this is called function call by reference. When we pass an address as an argument, the function declaration should have a pointer as a parameter to receive the passed address.
