bookChallenge: Why Do We Need Array Size as an Argument?

Opgave

Swipe to start coding

You are creating a student analytics tool that calculates the average score from a list of grades stored in a dynamic array.

  1. The function calculateAverage takes a pointer to an integer array scores and an int n representing the number of elements.
  2. Initialize a variable sum to 0 before the loop.
  3. Use a loop to iterate over the array from 0 to n.
  4. In each iteration, add the current element to the variable sum.
  5. Return the average score by dividing sum by n.

Example

{80, 90, 75, 85, 100} => 86.0
{60, 70, 80} => 70.0
{100, 90, 95, 85} => 92.5
