C++ Developer - Project - Return the Sum of Built-In Array Elements

The video tutorial guides viewers through creating a function called 'sum array' that takes an array of integers and its size as parameters, and returns the sum of the integers. The instructor explains the function's implementation, including setting up a project, writing the function, and testing it. The tutorial emphasizes using a regular for loop to iterate through the array and discusses alternative methods. The video concludes with a preview of the next project, which involves using an array object instead of a built-in array.

What should you do to test the 'sum' function after creating it?

How can you call the 'sum' function from the main function?

What alternative methods could be used to iterate through the array instead of a regular for loop?
