Code Challenge 4.4 - Average Finder

---

Objective

Your task is to write a program that calculates the average value of a collection. You will implement a function to find the average value.

Skills to Practice

• Defining functions/methods.
• Passing arguments to functions.
• Returning values from functions.
• Iterating through collections.

Challenge Tasks

• Create a console project named Challenge 4-4.
• Define a function/method to calculate the average value of a collection.
  • If you’re using a statically typed language, such as C#, you may specify either an array or a list for the parameter type.
• Example signatures:

Python

def find_average(collection):
    # code here

C#

double FindAverage(int[] collection)
{
    // code here
}

// -or-

double FindAverage(List<int> collection)
{
    // code here
}
