 In C, you use a for loop to iterate through an array. In fact, for loops and arrays were pretty much made for each other. Here's the array of scores, again. And we want to find the average score. We'll set a double sum to 0.0 and then run a for loop with an integer index starting at 0. The index will go up to but not including 5. And at the end of each loop iteration, we'll increment the index by 1. The body of the loop will set the sum to its previous value plus the element of the array at the given index. Create a double variable named Average and set it to sum divided by 5. And then print the result properly labeled. Let's build it and run it, and that's our average score. Other languages have shortcuts for iterating through an array, such as for each or list comprehensions. But in C, you use a standard for loop to iterate through an array.
