Lesson 05: Function Overloading and Default Arguments

Suppose there is a function that calculates the average of an array of numbers of type int. The function might look like this:

float iAverage(int array[], int length)
{
    int     sum = 0;
    int     j;

    for (j = 0; j < length; j++)
        sum += array[j];

    return (float) sum / length ;
}
