Average of a stream of numbers - GeeksforGeeks
Given a stream of numbers, print average (or mean) of the stream at every point. For example, let us consider the stream as 10, 20, 30, 40, 50, 60, …

float getAvg (int x)

{

    static int sum, n;

 

    sum += x;

    return (((float)sum)/++n);

}

 

// Prints average of a stream of numbers

void streamAvg(float arr[], int n)

{

   float avg = 0;

   for(int i = 0; i < n; i++)

   {

       avg  = getAvg(arr[i]);

       printf("Average of %d numbers is %f \n", i+1, avg);

   }

   return;

}
