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 is the primary task of the 'sum array' function?

• To multiply all elements in the array

• To sort the array in ascending order

• To find the maximum value in the array

• To sum the integers in the array

What is the recommended way to pass the array to the function?

• Use empty brackets and pass the size separately

• Use a pointer to the array

• Include the size in the square brackets

• Pass the array as a string

What type of loop is suggested for iterating through the array?

• While loop

• Do-while loop

• Regular for loop

• Recursive function

What is the first step in implementing the 'sum array' function?

• Sort the array

• Initialize the sum to zero

• Print the array elements

• Find the maximum element

How should the function be tested?

• By calling it from the main function with a test array

• By using a debugger

• By writing a separate test script

• By using a third-party testing tool

What is a potential alternative to passing the array size?

• Using a recursive function

• Using a different type of for loop

• Using a global variable

• Using a while loop

What is the output of the function when the array is [25, 210, 20, 15, 100, 25]?

• 395

• 400

• 395

• 420
